🕒 5,000+ hours on Upwork
✅ 8+ years of experience
✅ 50+ projects delivered
✅ Excelling in delivering Fortune 100-scale projects
8+ years of experience as a software engineer, and have worked at both small startups and large organizations. While I'm a proficient full-stack developer, my expertise is in building scalable Applications in (.NET Core, CQRS, Azure, API Services, ASP.NET MVC C#, MS SQL Server, VB.NET, EFCore, MongoDb, JIRA, Git, RabbitMQ, QuickBooks Integration, Micro Services, BitBucket, Unit Testing and DevOps).
One recent project involved migrating a large legacy ASP MVC app to ASP.NET Core SaaS app. Responsible for implementing:
- ASP.NET Core app with Core Identity for authentication and authorization
- I also implemented JWT Token based claims and authentication.
- REST API for WordPress clients
- EF Core code first with SQL server
- Background service for implementing long running tasks from API requests
- SignalR for notifying clients of the status of the long running tasks
- Stripe integration for one off card charging, and monthly subscriptions
Another large project for a financial services firm involves:
- working with a UI designer to redesign the UI (Bootstrap, jQuery, CSS, JS)
- next phase to redesign back end with new REST API for a new Angular client
Professionally, I have B.S (Software Engineering)

I build production React, Next.js & Laravel SaaS platforms with AI, LLM, and automation systems engineered in from day one, not bolted on after launch.
🏆 𝐓𝐨𝐩 𝐑𝐚𝐭𝐞𝐝 𝐏𝐥𝐮𝐬 | 💯 𝟏𝟎𝟎% 𝐉𝐨𝐛 𝐒𝐮𝐜𝐜𝐞𝐬𝐬 𝐒𝐜𝐨𝐫𝐞 | 🤖 𝐂𝐞𝐫𝐭𝐢𝐟𝐢𝐞𝐝 𝐂𝐥𝐚𝐮𝐝𝐞 𝐂𝐨𝐝𝐞 𝐄𝐱𝐩𝐞𝐫𝐭
Over 10 years I've delivered React/Next.js frontends, Node.js and Laravel backends, and Python AI backends for SaaS founders, healthcare platforms, and workflow-automation startups, from fixed-price MVP builds with hard 3-week deadlines to long-term ownership of production codebases with active, paying users.
⚙️ 𝐅𝐔𝐋𝐋-𝐒𝐓𝐀𝐂𝐊 𝐄𝐗𝐏𝐄𝐑𝐓𝐈𝐒𝐄
Frontend: React, Next.js (App Router), TypeScript, JavaScript, Tailwind CSS, shadcn/ui, Sanity CMS integration, complex state-heavy interactive UIs (scheduling/calendar systems), Core Web Vitals and SEO optimization, pixel-perfect Figma-to-code.
Backend & SaaS: Node.js, NestJS, Laravel, PHP, Python (FastAPI, Django, Flask), Prisma ORM, REST and GraphQL APIs, JWT/OAuth/Supabase Auth, multi-tenant SaaS architecture, Stripe subscription billing, PostgreSQL, MongoDB, MariaDB.
Cloud & DevOps: AWS, Docker, Vercel, Supabase, Firebase, Redis, CI/CD pipelines, Nginx, WebSockets and real-time systems.
🤖 𝐀𝐈 & 𝐀𝐔𝐓𝐎𝐌𝐀𝐓𝐈𝐎𝐍 𝐄𝐍𝐆𝐈𝐍𝐄𝐄𝐑𝐈𝐍𝐆
🏅Certified Claude Code Expert, verified credential, not a self-claimed skill tag.
I've built LLM orchestration layers with retry logic, streaming responses, and guardrail systems, input classifiers, output filters, and rate limiting, for conversational AI modules that handle real user sessions, not demo scripts.
⚡Async AI processing pipelines using BullMQ & Redis job queues, turning raw input (call transcripts, uploaded documents) into structured, validated output on a queue architecture built to survive production load.
🌐Browser automation & AI document processing: Python and Playwright engines that navigate dynamic third-party websites, paired with GPT-4o Vision to extract structured data from scanned PDFs and images for downstream automation.
💡Daily AI-native development workflow: Claude Code, Cursor, Lovable, and Windsurf, used inside real client codebases to accelerate delivery, not just referenced as buzzwords.
🧠RAG pipelines, vector search (Pinecone), n8n, Automation, LLM Integration, and LangChain-based AI agents for document-grounded chat, retrieval, and knowledge assistants.
🤖AI agents & workflow automation | LangChain/LangGraph agents, RAG pipelines, n8n automations that replace manual processes
🏗️ 𝐈𝐍𝐃𝐔𝐒𝐓𝐑𝐈𝐄𝐒 𝐈'𝐕𝐄 𝐁𝐔𝐈𝐋𝐓 𝐅𝐎𝐑
SaaS and workflow-automation platforms, Healthcare and HealthTech (patient/provider data platforms), iGaming and affiliate MarTech (GPT-driven, SEO-heavy platforms), FinTech, EdTech, and enterprise internal tools including CRM/WMS systems.
🎯 𝐖𝐇𝐘 𝐂𝐋𝐈𝐄𝐍𝐓𝐒 𝐊𝐄𝐄𝐏 𝐌𝐄 𝐎𝐍 𝐑𝐄𝐓𝐀𝐈𝐍𝐄𝐑
→ I own backend, frontend, AI integration, and deployment under one contract. No handoff gaps between a frontend developer, a backend developer, and an "AI person" one accountable owner, start to finish.
→ I've delivered inside hard fixed-price sprints, a 3-week, 5-milestone backend-plus-AI build with zero missed deliverables, and inside open-ended, long-term maintenance contracts on live production codebases still generating revenue today.
→ I use Claude Code, Cursor, and Lovable inside real client codebases to move faster, without leaving behind code that can't be handed to another developer six months later.
→ I ask what the business outcome is before I choose the stack. The right architecture is the one that ships and holds up under real usage, not the most technically interesting option on the table.
𝐒𝐞𝐧𝐝 𝐦𝐞 𝐢𝐧𝐯𝐢𝐭𝐞, 𝐭𝐡𝐞 𝐣𝐨𝐛 𝐩𝐨𝐬𝐭 𝐨𝐫 𝐚 𝐬𝐡𝐨𝐫𝐭 𝐝𝐞𝐬𝐜𝐫𝐢𝐩𝐭𝐢𝐨𝐧, of what you're building. I'll tell you directly whether it's a fit, flag any risk in the scope before you commit, and give you a realistic timeline.

If your ASP.NET or .NET Core application is unstable, hard to maintain, or stuck on legacy code, I can help.
I work on production systems where changes have real impact. Most of my projects involve stepping into existing codebases, understanding how they evolved, and improving them without breaking what already works.
Typical situations I handle:
- Recurring production bugs
- Legacy .NET Framework upgrades
- Tight coupling and accumulated technical debt
- Slow APIs and inefficient database queries
- Fragile deployment processes
In some cases a rewrite makes sense. In many others, targeted improvements deliver faster and safer results. I focus on choosing the approach that fits the system and the business constraints.
My core stack includes C#, ASP.NET Core, Web API, SQL Server, and Azure-based deployments.
If this matches your situation, send a short summary of the issue. I will review it and suggest a practical next step before any commitment.
Tell us what you need. Create your own job post or generate one with AI then filter talent matches.
