Job Success
Lucknow, India - 2:18 am local time
Top Rated Plus on Upwork — 100% Job Success across 60+ shipped projects
and 11,700+ billed hours.
I'm not an AI engineer who learned to code last year. I'm a senior
engineer who spent a decade shipping production SaaS — React, Node,
Python, Postgres, AWS — and evolved into AI because that's where the
hardest, most interesting problems are now. That foundation is why
my AI projects actually ship to production instead of dying as demos.
If you're building an AI product that needs to scale, handle real
users, integrate with real systems, and not bankrupt you on OpenAI
costs — that's the engineer you want.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
WHAT I BUILD
- Custom LLM applications — OpenAI, Anthropic Claude, open-source
models. Chatbots, copilots, document processors, classifiers,
summarization tools, content generation pipelines.
- RAG systems — retrieval-augmented generation over your private
documents, databases, or APIs. pgvector, Pinecone, Qdrant. Tuned
for accuracy, latency, and cost.
- AI agents — multi-step agents that use tools, call APIs, and
complete real work. LangChain, LangGraph, or custom orchestration
when frameworks get in the way.
- AI-powered SaaS — the full product, not just the AI piece. From
schema design to React frontend to OpenAI integration to
production deployment.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
RECENT PRODUCTION WORK
- AI Invoice Processor — automated financial data extraction at
scale. OCR + LLM pipeline. Processes thousands of invoices with
structured output and minimal human review.
- DatainsightAI — natural language interface over enterprise
analytics data. Users ask questions, AI returns charts and
insights.
- Insight AI — meeting intelligence platform. Transcription,
summarization, action item extraction, follow-up automation.
- HotSpotSEO — production SaaS with AI-generated content pipelines,
scheduled background jobs, and multi-tenant architecture.
- Visoshare — AI video summarization and transcription product.
OpenAI-powered, streaming responses, file upload pipelines.
- Healthcare research SaaS — RAG over HCP, patient, and care-
partner data. Multi-tenant on Auth0. Five product surfaces on a
shared schema.

THE EVOLUTION
2013–2020: Backend & full-stack engineer. Production SaaS in
fintech, healthcare, e-commerce. Learned what "scale"
actually means.
2020–2023: Senior full-stack on Upwork — Next.js, React, Node,
Python, AWS. 60+ projects, 100% JSS, Top Rated Plus.
2023–today: AI engineer. Custom LLM apps, RAG systems, AI agents,
AI-powered SaaS. Same engineering rigor, applied to the
most interesting problem space in software today.
The engineering didn't change. The interface did. Today the
function call goes to OpenAI or Claude instead of just a database.
The system around it still needs to be built right — and that's
what most "AI developers" can't do.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
TECH I SHIP WITH
AI: OpenAI, Anthropic Claude, LangChain, LangGraph, pgvector,
Pinecone, Hugging Face, prompt engineering, function
calling, structured outputs, evals, streaming.
Backend: Node.js, NestJS, Python, FastAPI, PostgreSQL, MongoDB,
Redis, REST, GraphQL.
Frontend: React, Next.js (App Router), TypeScript, Tailwind,
shadcn/ui.
Infra: AWS, Vercel, Docker, Cloudflare, CI/CD.

HOW I WORK
The first 30 minutes are free. I'll tell you honestly whether your
idea needs AI or just better software, what's actually buildable in
your budget, and where the real risks are. If we're a fit, we move
forward. If not, you've still got a clearer picture than when we
started.
I work as a senior engineer directly with you — not an account
manager handing off to a junior. You communicate with me, I write
the code, you ship the product.
Available 30+ hours/week. Comfortable working async across US, EU,
and APAC time zones.
Ready when you are.
