🔧 12+ Years Building Scalable Web Apps | SaaS Platforms & AI Systems | 100% Job Success | Global Clients When your product needs someone who can contribute across the full stack, from architecture and backend systems to frontend, cloud, and AI integrations, I can help bring that together reliably. I’m a Full-Stack Developer and Solution Architect with 12+ years of experience building production systems for startups, SaaS companies, and enterprise clients across the US, UK, Canada, and Europe. I’ve also led engineering teams and delivered complex projects across different domains. ⚙️ WHAT I BUILD ───────────────────────────────────────── ✅ SaaS platforms — multi-tenant, role-based, scalable from day one ✅ REST APIs & microservices — clean, documented, and production-hardened ✅ AI-powered applications — LLM workflows, AI agents, Azure AI Foundry pipelines ✅ Cloud-native systems — Azure & AWS architecture ✅ Full-stack web apps — .NET / Node / React / Next.js, end to end ✅ Auth & RBAC — Clerk, Azure B2C, JWT, multi-tier permission systems 🛠️ CORE STACK ───────────────────────────────────────── Backend: .NET Core / C#, Node.js, NestJS, ASP.NET MVC Frontend: React, Angular, Next.js, TypeScript AI: Azure AI Foundry, OpenAI API, Claude API, LLM Agent Systems Cloud: Azure (App Service, Foundry, Container App), AWS (EC2, S3, SQS, SNS, Lambda) Databases: PostgreSQL, MSSQL, Supabase Auth: Clerk, Azure B2C, JWT 🚀 RECENT WORK HIGHLIGHTS ───────────────────────────────────────── → Fundraising SaaS (TzFund): Architected a modular REST API with 4-tier RBAC and Clerk webhook-based auth sync on Azure — real-time donor management at production scale. → Pharmacy Management System: Led full delivery — architecture to Azure deployment — with real-time stock dashboards and multi-view reporting. → Sports Booking Platform: Multi-venue, real-time slot availability with row-level database security and zero-downtime CI/CD on Vercel. → Virtual Exhibition Platform: Built and delivered a real-time attendee management system across Azure and DigitalOcean as solo technical lead. → Liberty CRM (Canada): Role-based CRM with automated invoicing and structured lead pipeline in Angular + .NET Core. → CARE-NG (UK Charity): Unified CRM, fundraising, donor management, and membership platform. 🤖 AI INTEGRATION — NOT A BUZZWORD, A PRACTICE ───────────────────────────────────────── I've built AI agent systems using Azure AI Foundry for automated emails, reports and tasks, created LLM pipelines with OpenAI and Claude that produce structured outputs from API data, and use AI-assisted development tools (Cursor, Claude Code) to ship faster without sacrificing code quality. I design systems where AI is a core feature — not an afterthought bolted on at the end. 💡 WHY CLIENTS CHOOSE ME ───────────────────────────────────────── Most developers can write code. Fewer can make the right architectural calls when it matters — under deadline pressure, with incomplete requirements, or when a technical decision made today will cost you six months of refactoring tomorrow. My 12 years of shipping real systems in real-world conditions means I bring that judgment to every project. Clear communication and working in chaos in my forte 📩 READY TO START ───────────────────────────────────────── Send me an invite or message me with your project details. I'll respond with a clear plan of how I'd approach it — no fluff, no overselling. Let's build something that lasts.
