Hire a senior full-stack AI engineer
I'm Yaseen Nurmahammad Khatib — five years building for the web end to end, the last few wiring that into production AI. I ship complete systems solo: five products in the last twelve months, from a Rust desktop app to autonomous pipelines. Everything on this site actually runs.
What I build
Agentic RAG systems
Retrieval that grounds and cites — hybrid search, reranking, guardrails, and the eval loop that proves it works.
LLM orchestration & agents
Reason → act → observe loops, tool use, memory, and the safety boundaries that make a probabilistic model production-safe.
Full-stack MERN apps
React, Node, TypeScript, MongoDB — from schema to deployment, built to hold up under real users, not a demo.
Real-time & edge
WebSockets, streaming, and serverless on Cloudflare Workers + Hono — low-latency systems that scale past one process.
On-device & local-first AI
Private, offline-capable AI where the data never leaves the device — SQLite, function calling, local retrieval.
FinOps & performance
Token-cost governance, caching, and serialization work — including a 94% payload cut on a real workflow engine.
Proof, not promises
This site's whole thesis is real artifacts over claims. Read the engineering decisions behind Sable (a local-first AI finance agent that keeps 100% of data on-device), streamerOS (a Rust desktop cockpit plus a serverless RAG support agent on the edge), and the 94% payload cut on IntegrateX. Or browse every product and the writing behind the decisions.
How I work
Solo, end to end
Schema to deployment — no hand-offs, no coordination tax. You get one person who owns the whole system.
Production-first
Built for real users and real failure modes, not a happy-path demo. Guardrails, tests, and honest limits.
Fast, AI-native
An AI-augmented workflow that ships in days what used to take weeks — without cutting the corners that matter.
Honest by default
No fabricated metrics or vanity claims. If a number is here, it's real — that's the whole point of this site.
Ways to work together
Full-time
Senior or lead engineer, remote / hybrid / on-site. Open now.
Contract / freelance
A defined build or an ongoing engagement — I own it end to end.
Consulting
Architecture reviews, RAG/agent design, or unblocking a stuck AI feature.
Based in Hyderabad, India (IST) — comfortable remote, hybrid, or on-site, and effective across global time zones.
