Building the Future with Intelligent Software Solutions

CodeChoicez delivered this full-stack SaaS platform end-to-end — from database schema and business logic to UI design and third-party integrations — on the latest .NET 10 and Blazor Server stack.The platform connects Belgian homeowners with verified construction companies through a credit-based lead marketplace. It serves three distinct user types, each with their own isolated portal and tailored experience.The Three PortalsHomeowner PortalHomeowners register, describe their renovation project (roofing, solar panels, kitchen, bathroom, electrical, plumbing, etc.), upload photos, and specify their address. The system automatically validates Belgian postal addresses via the bpost Address Proofing API. Once submitted, the project enters the marketplace where matching companies can unlock contact details.Company (Contractor) PortalVerified Belgian construction companies register through a multi-step onboarding wizard that validates their VAT number in real time against the European VIES (VAT Information Exchange System) API. After email confirmation, they access a dashboard where they can:View new leads matched to their service categories and regionPurchase credit packs via Stripe (fully automated online payments)Spend credits to unlock homeowner contact detailsTrack accepted, unlocked, and skipped leadsMonitor their credit balance and full transaction historyEarn referral rewards when companies they referred make purchasesManage their company profile, team members, and account settingsSet up Two-Factor Authentication (TOTP) or passwordless PasskeysSwitch the interface language (English, French, Dutch)The company sidebar stays consistent across all pages — including account-management pages like Change Password, 2FA settings, and Passkey management — ensuring a professional, unbroken experience.Admin

OverviewBeanFlow is a production-grade SaaS platform that gives specialty coffee roasters and cafés one precise dashboard for everything between green coffee and the cup — green inventory, roast logs, drink COGS, wholesale invoicing, retail bag sales, and multi-location stock transfers.Built ground-up over multiple beta-feedback rounds with real roasters (Tony N., Micah, David at Zaca Coffee), every feature ships only after the user requesting it has signed off on it live.🔗 Live: beanflow.ioThe ProblemMost roasters track inventory in spreadsheets and COGS in their head. They lose money to invisible shrink, mispriced wholesale bags, and packaging cost mistakes. Existing tools are either too generic (QuickBooks) or too narrow (Roastime).The SolutionA two-mode SaaS — Roaster and Cafe — that automates the inventory-to-COGS pipeline:Roaster ModeGreen Profiles with auto-calculated landed cost (base + freight + customs per lb)Roast Log — Single Batch OR Blend Batch (up to 3 green coffees with % sliders), auto-deducts green inventory, computes per-lb costRoast Groups — combine multiple separate roasts under one shared packaging costPackaging-aware roasted inventory — tracks loose vs bagged stock per bag size for accurate salesWholesale Sales Orders with QuickBooks sync + auto-email invoicingMulti-location transfers — move roasted stock to specific cafe locationsCafe ModeRecipes with multi-size pricing (3oz → 30oz variants)Daily Sales Log with Square POS CSV importModifier-aware deduction — oat milk swaps re-route from oat inventory, extra shots add bean usageSales Summary with week/month / all-time rollups, latest-day fallbackLive drink COGS with retail bag sales trackingSharedPer-card "Manage" pills route directly to edit modals — one click to full detailsReal-time Firestore sync across devicesCustom QuickBooks + Shopify integrationsStripe-ready payment plan toggle (Roaster Pro / Cafe Pro / Multi-Location)WebAuthn passkey login for password-less accessAdmin panel for user management + chat oversightEngineering Highlights17+ pages, deeply mode-aware (Roaster vs Cafe surfaces different navigation, recipes, and stats)34/34 unit tests passing — pure calculation logic for COGS, roast loss, blend cost math, bag-size parsingTypeScript-strict end-to-end — zero any leakage in business logicFirestore security rules for multi-tenant data isolation with location-scoped accessCloud Functions for OAuth callbacks (QuickBooks, Shopify, Square), invoice email delivery, and scheduled reorder PO senderCI/CD via Firebase Hosting with named Firestore databaseMy RoleEnd-to-end ownership — product discovery, architecture, full-stack implementation, integration wiring, deployment, and iterative shipping against real-user beta feedback rounds.

A one-stop property care company in Singapore needed more than a brochure site. ProCare.SG handles moving, cleaning, painting, repairs and maintenance. They had a designed frontend but no backend — every content change meant calling a developer, and enquiries had nowhere to go.We completed it into a production website with a custom admin dashboard the owner runs entirely themselves.What we builtPublic website — 24 pages across services, portfolio, blog, testimonials and contact, fully responsive across mobile, tablet and desktopCustom admin dashboard — seven modules: portfolio projects, blog articles, testimonials, contact enquiries, per-page SEO, tracking-script injection and administrator accountsRich-text article editor — headings, formatting, lists, links and image uploads, with no third-party editor dependencyEnquiry management — form submissions captured with status tracking, private internal notes, CSV export and email notificationsServer-rendered SEO — metadata rendered before the page is sent, so search engines and WhatsApp, Facebook and LinkedIn link previews read it correctly on every pageAuto-generating sitemap — new projects and articles appear for search engines the moment they're publishedBuilt for the long runSecurity is enforced at the database, not just the interface: administrator access is a server-issued token claim checked on every read and write. The contact form is validated, rate-limited and honeypot-protected, and customer photos stay private to the dashboard.We also cut the page weight hard — imagery from 14.7 MB to 2.25 MB, JavaScript from 444 KB to 282 KB. The result scores 100 for SEO and 100 for Best Practices on Google Lighthouse.Stack: React 19 · Firebase (Firestore, Auth, Storage, Cloud Functions) · Tailwind CSS · Firebase Hosting, Singapore region

OverviewDMS (Distribution Management System) is a production-grade Windows desktop built for wholesale distributors and FMCG suppliers. It runs an entire distribution business from one app point-of-sale billing, customer and company ledgers, field-salesman tracking, inventory, routes and reporting and it works fully offline, so the shop floor never stops when the internet does.Built around a fast, image-rich POS and a rock-solid double-checked ledger, DMS replaces the stack of registers, spreadsheets and WhatsApp messages most distributors juggle today.The ProblemMost distributors run on paper or Excel. The result is predictable: bills take minutes to cut at the counter, customer balances are guesses, salesman returns vanish into the margins, and "how much does this shop owe us?" takes an hour to answer. Generic accounting tools (QuickBooks) are too broad and online; POS apps are too narrow and need constant connectivity.They needed something specific to distribution, fast, offline, and trustworthy with money.🔐 Secure Login & Access ControlDMS opens on a clean, branded sign-in screen that sets the tone for the whole app. Users log in with a username and password, with a "Remember me" option for trusted machines and a Forgot Password recovery flow for quick resets. New team members can be brought on through the built-in Register tab.Behind the login sits role-based access control (Admin / User) and online license activation so the software only runs on authorized machines, and each user sees exactly what their role allows. It keeps the business's data both secure and always available.📊 Dashboard & Sales AnalyticsThe moment a user logs in, the dashboard gives a live pulse of the whole business. Colour-coded KPI cards surface the numbers that matter most total products, active shops, delivery routes, low-stock alerts and pending payments so nothing slips through the cracks. A built-in Sales Analytics chart breaks revenue down month-by-month with a quick year filter, turning raw bills into trends at a glance. It's the daily command center: know exactly where the business stands before making a single call.⚡ Lightning-Fast Point of SaleA touch-friendly POS with a searchable, image-based product grid and a live bill panel. Add items, apply discounts and create a bill in seconds even with thousands of products loaded. Each bill is automatically posted to the right customer's ledger and the selling salesman's record.📦 Inventory & Stock ControlEvery product the business sells lives in one central catalog organized by category, with separate trade and sale pricing and live on-hand quantities. DMS watches stock levels automatically and flags items as Low or Out of Stock, so reorders happen before a shelf goes empty. Search any product in an instant, add new ones in seconds, and trust the numbers: sales draw stock down and returns put it back the moment they're booked keeping on-hand quantities always in sync with reality.➕ Adding a ProductBuilding the catalog is quick and thorough. Each product captures everything the counter and the accounts need name, category, company/brand, size, and a product photo plus a full three-tier pricing setup: company, trade and retail price, so margins are baked in from day one. Set the opening stock quantity and the item is instantly ready to sell in the POS and tracked in inventory. The image-based catalog means staff recognize products at a glance instead of hunting through codes.🧾 Bills History & ReportingEvery bill ever made, searchable and filterable (including a Paid-only filter), synced straight from the POS. Export any view to Excel for accounts, audits or owner reviews.🚚 Routes & Distribution CoverageDistribution runs on beats, so DMS lets you organize the whole territory into delivery routes. Each route has a name and description and shows the number of shops assigned to it at a glance. Open any route to view and edit its details, then drill straight into the shops on that route turning a plain list into a real map of where sales happen. Routes tie directly into customer ledgers and salesman activity, and the whole view exports to Excel or CSV for planning and reporting.📒 Customer Ledger & Receiving'sEvery customer gets a clean, paginated ledger with Total Bills, Total Received, Outstanding and Excess computed live in SQL accurate over tens of thousands of records. Payments are recorded as customer-level receiving's, returns reduce the balance automatically, and cleared bills are flagged so collections are obvious at a glance. One-click Excel export produces a fully reconciling statement.🏢 Company Ledger (Supplier Accounts)Where the customer ledger tracks money coming in, the Company Ledger tracks money going out to suppliers. Each company keeps its full profile name, address, contact, email and saved bank/payment details alongside a complete purchase ledger. Every entry captures the real accounting picture: invoice number and amount, fare, claim, net payment, paid and remaining amount, and any excess/advance, plus the payment mode, account number and transaction ID for a clean audit trail. Scanned invoices and receipts can be attached right to the entry, and balances roll up automatically, so you always know exactly what's owed to whom.👥 Employee & Salesman ManagementEvery field salesman lives on one screen, with their full profile name, phone, CNIC, monthly salary and incentive (fixed or percentage). But it's more than a contact list: each row is a control panel. In one click you can open that salesman's Bills, Returns, Sales report or Daily Sales Report (DSR) and edit or remove them with the right permissions. It ties the whole field team back to real numbers, so you can see exactly who sold what, who's carrying returns, and how each person is performing.Here's the Settings section, matching your real Settings screen (profile, company info, logo, security questions, password, tax & stock config):⚙️ Settings & System ConfigurationOne place to tailor the whole application to the business. Under Profile & Account, users manage their username, email, phone and profile picture/logo, change their password, and set security questions that power the Forgot-Password recovery. Company Information and a custom logo flow through onto invoices and across the app. And System Settings put the business rules in the owner's hands the currency symbol, a low-stock alert threshold, and configurable GST, Sales, Advance and Other tax percentages applied automatically to bills. Admins get full privileges; everything stays consistent everywhere it's used.The ResultDMS turns a paper-and-spreadsheet distribution business into one fast, offline-first desktop platform where a bill takes seconds, every rupee is accounted for, and the owner can answer "how are we doing?" in a single glance. Built for the real shop floor: fast, reliable, and secure.Have a business that runs on registers and guesswork? CodeChoicez builds custom desktop and full-stack software that fits exactly how you work let's build yours.

Talent Acquisition is a full-stack, AI-powered recruitment platform that automates the entire hiring funnel — from job posting and candidate application through CV screening, multi-phase technical and voice assessment, interview scheduling, and final recruiter decision support. It brings recruiters, candidates, and interviewers into one integrated flow across web and email, replacing manual CV triage and scattered tooling with a single intelligent pipeline.The Problem It SolvesTraditional hiring is slow and inconsistent: recruiters manually screen hundreds of CVs, interview quality varies, scheduling drags across email chains, and assessment integrity is hard to guarantee.
