Senior Full-Stack Developer & AI Engineer

The Engineer Behind the Architecture, the Code, and the Decisions

Technical Decision Maker

Architecture decisions. Stack selection. AI integration strategy. Database design. Scalability planning. These are the calls that make or break a product — and I've made them across 62+ real-world projects, from real-time gaming platforms with WebRTC to AI-powered SaaS tools with LLM pipelines and RAG systems. When the hard technical questions arrive, I don't guess. I decide — and I've been right.

Always On, Always Shipping

My response time is minutes — not hours, not "I'll get back to you." Clients across the US, Europe, and Asia rely on me because when they need an answer or a fix, they get it immediately. A 100% Job Success Score on Upwork is the result of fast decisions, clear communication, and code that ships without drama. I don't just deliver features — I own the outcome.

Answers to the Questions I Get Most

Everything you need to know before we start working together — from my process and stack to timelines and how to reach me.

Get in Touch

What kind of projects do you take on?

I specialize in full-stack web apps, AI-powered applications, SaaS platforms, MVPs, API integrations, and React Native mobile apps. I work best with startups and growing businesses that need a reliable developer who can own the full product — from architecture to deployment.

How long does a project typically take?

It depends on scope and complexity. A focused MVP or feature build can ship in 2–4 weeks. A full SaaS platform or AI-powered system typically takes 2–4 months. I always provide a clear milestone roadmap after an initial discovery call so there are no surprises.

Can you integrate AI into an existing product?

Yes — this is one of my core strengths. I integrate OpenAI APIs, build LLM-powered features, create RAG (Retrieval-Augmented Generation) systems, and wire up AI agents into existing platforms. I've done this across SaaS tools, customer support systems, and internal automation workflows.

Do you provide post-launch support and maintenance?

Absolutely. Many of my clients on Upwork have worked with me for 1–2+ years across multiple contracts. I offer ongoing bug fixes, feature additions, performance improvements, and infrastructure scaling as your product grows.

What is your tech stack?

Frontend: Next.js, React, TypeScript, Tailwind CSS, Material UI. Backend: Node.js, Express, NestJS, Python. Databases: PostgreSQL, MongoDB, Supabase, Redis. Mobile: React Native. AI/ML: OpenAI, LangChain, vector DBs. Payments: Stripe. Comms: Twilio. DevOps: Vercel, Docker, GitHub Actions.

How do we get started?

The easiest way is to reach out via Upwork or the contact page here. I respond within minutes. We'll have a quick call to understand your requirements, and I'll send a clear project plan with timeline and budget. No fluff — just straight to building.

Why should I hire you over an agency?

You get direct access to the person actually building your product — no account managers, no handoffs, no markup. I bring senior-level expertise (4+ years, 62+ projects, 100% Job Success on Upwork) with the speed and communication of a dedicated partner. You always know the status and can reach me directly.
