Senior AI Engineer with 12 years of full-stack engineering behind me.
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.

Why clients keep coming back:
✔️ 100% Job Success Score across 99 projects
✔️ Clear communication and fast response time (0-4 hours)
✔️ End-to-end delivery — strategy, build, deployment, and support
✔️ Long-term partnerships, not one-off gigs — many clients rehire me for follow-on work
Let's talk about what you're building. Message me and I'll give you a clear, honest read on scope, timeline, and approach before we start.

AI Agent Developer | AI Automation Expert | Forward Deployed Engineer ( FDE ) | Voice AI Agents & Automation | AI Chatbot Development | OpenAI, Claude, RAG, LangChain, MCP, OCR
✅ 10+ Years of Experience in AI, AI Automation & Software Development
✅ AI Agents, Voice Agents & Multi-Agent Systems
✅ OpenAI, Claude, Gemini & Custom LLM Integrations
✅ RAG Systems, Knowledge Bases & AI Search
✅ Workflow Automation & Business Process Automation
✅ Long-Term & Enterprise Project Experience
Greetings, I am Usman, a certified AI agent developer and forward deployed engineer. I build production-ready AI agents and automation systems that cut overhead by 40–70%, deployed inside your real stack through system integration and legacy system integration.
Every project runs on spec-driven development — a full architecture, data flow, tool design, and acceptance criteria, before a single line of code is written. I've delivered AI agents, AI chatbots, voice AI agents, workflow automation, and business process automation across Healthcare, FinTech, SaaS, Real Estate, and Sales, working directly with your team through client-facing technical delivery.
——— 𝐏𝐫𝐨𝐯𝐞𝐧 𝐀𝐈 𝐀𝐠𝐞𝐧𝐭 𝐑𝐞𝐬𝐮𝐥𝐭𝐬 ———
𝐇𝐞𝐚𝐥𝐭𝐡𝐜𝐚𝐫𝐞 𝐀𝐈 𝐀𝐠𝐞𝐧𝐭: Automated patient onboarding, EMR management, and appointment scheduling. Cut admin errors across the workflow.
𝐅𝐢𝐧𝐓𝐞𝐜𝐡 𝐀𝐈 𝐀𝐠𝐞𝐧𝐭: Built a QuickBooks automation layer that detects invoices, syncs data, and sends AR follow-ups without manual tracking.
𝐅𝐢𝐧𝐚𝐧𝐜𝐞 𝐒𝐚𝐚𝐬 𝐌𝐮𝐥𝐭𝐢-𝐀𝐠𝐞𝐧𝐭 𝐒𝐲𝐬𝐭𝐞𝐦: Built an agent network automating finance, HR, and marketing workflows in parallel for an enterprise client — one system instead of three separate tools.
𝐒𝐚𝐥𝐞𝐬 𝐀𝐈 𝐀𝐠𝐞𝐧𝐭: Real-time coaching system that analyzes live calls, tracks KPIs, and gives feedback right after each call instead of during a weekly review.
𝐑𝐞𝐚𝐥 𝐄𝐬𝐭𝐚𝐭𝐞 𝐀𝐈 𝐀𝐠𝐞𝐧𝐭: Built a home valuation platform that generates multi-tier pricing reports, renovation recommendations, and market comparisons automatically.
𝐖𝐡𝐚𝐭 𝐈 𝐜𝐚𝐧 𝐝𝐞𝐥𝐢𝐯𝐞𝐫 𝐭𝐨 𝐲𝐨𝐮:
——— 𝐀𝐈 𝐀𝐠𝐞𝐧𝐭 𝐃𝐞𝐯𝐞𝐥𝐨𝐩𝐦𝐞𝐧𝐭 ———
I design custom AI agents and multi-agent systems with LangChain, LangGraph, CrewAI, AutoGen, the Claude SDK, and the OpenAI Agent SDK. Each system includes memory management, tool orchestration, error handling, and observability built for production traffic, not a prototype. I also build MCP (Model Context Protocol) servers so an agent connects to any external tool, API, or data source through one standard interface.
——— 𝐅𝐨𝐫𝐰𝐚𝐫𝐝 𝐃𝐞𝐩𝐥𝐨𝐲𝐞𝐝 𝐄𝐧𝐠𝐢𝐧𝐞𝐞𝐫 ———
As a Forward Deployed Engineer, I handle production deployment and system integration directly inside your real stack through client-facing technical delivery. Every build follows spec-driven development, connects through API integration and legacy system integration, and supports the same business process automation running across your operations.
——— 𝐑𝐀𝐆 𝐏𝐢𝐩𝐞𝐥𝐢𝐧𝐞𝐬 & 𝐀𝐈 𝐊𝐧𝐨𝐰𝐥𝐞𝐝𝐠𝐞 𝐀𝐠𝐞𝐧𝐭𝐬 ———
I build retrieval-augmented generation pipelines using LlamaIndex, LangChain, Flowise, and vector databases like Pinecone, Qdrant, Weaviate, ChromaDB. Whether your data lives in PDFs, databases, or internal systems, the agent retrieves and reasons over it directly.
——— 𝐒𝐜𝐚𝐥𝐚𝐛𝐥𝐞 𝐀𝐈 𝐀𝐮𝐭𝐨𝐦𝐚𝐭𝐢𝐨𝐧 𝐈𝐧𝐟𝐫𝐚𝐬𝐭𝐫𝐮𝐜𝐭𝐮𝐫𝐞 ———
For teams scaling AI automation beyond a single agent, I deploy distributed multi-agent systems on Ray enabling parallel agent execution, load balancing, and fault-tolerant AI workflow automation across large data volumes. This is enterprise-grade agentic AI, not a weekend prototype.
——— 𝐀𝐈 𝐂𝐡𝐚𝐭𝐛𝐨𝐭 & 𝐕𝐨𝐢𝐜𝐞 𝐀𝐈 𝐀𝐠𝐞𝐧𝐭 𝐃𝐞𝐯𝐞𝐥𝐨𝐩𝐦𝐞𝐧𝐭 ———
I build AI chatbots and conversational voice agents with the OpenAI API, Claude, Gemini, Vapi, Deepgram, and ElevenLabs, using natural language processing and machine learning for intent handling. These agents run lead qualification, patient intake, appointment scheduling, and customer support, connected into your CRM or helpdesk through API integration and AI model integration.
