AI Engineer · Doha, Qatar M.Sc. Artificial Intelligence · 10 years building production data systems
I build AI systems that reach real users — LLM applications, RAG assistants, computer vision pipelines and the automation that holds them together. My background is a decade of production data engineering and applied ML on large operational datasets, which is where I learned that the model is the easy part and the pipeline around it is the job.
CalTrack — nutrition tracking on Google Play Photograph a meal, get it itemised with calories and macros; get a meal plan built from your goals and body metrics. Two n8n workflows behind it: Gemini 2.5 Pro for the vision work, a gpt-5.1 agent for plan generation. No model call happens inside the app, so a prompt change doesn't need a store release.

AudioBooks — long-form text to AI-narrated audio summaries Map-reduce summarisation over a whole book, per-segment speech synthesis, then async concatenation into one track. Consumable credits with server-verified billing. React Native · Supabase · n8n · gpt-4o · ElevenLabs · Transloadit
E-commerce shipping automation — running in my own business Order event to courier booking: a model normalises free-text cities to courier codes, then routing by payment method and order value books the shipment, writes back tracking, and files the label. Make · Supabase · gpt-4o · TCS courier API
Voice appointment agent — appointment calls for a dental clinic Speech in, calendar out. Intent routing, natural-language date parsing, live slot lookup and calendar CRUD. Availability always comes from the calendar, never from the model. Make · VAPI · gpt-4o · Cal.com · Google Calendar
AI social publishing platform Generates copy and imagery, then publishes scheduled posts across Instagram, Facebook, LinkedIn and X with per-destination handling. Make · gpt-4o · DALL·E 3 · Supabase Storage
Lead generation pipeline Filters prospects, parses names, finds and verifies emails, writes a personalised icebreaker per lead. Unverifiable addresses are dropped rather than sent. n8n · LLM agents · AnyMailFinder · Instantly
Over 150 workflows built in n8n, plus Make scenarios. Eleven are documented in depth — sanitised exports, canvas diagrams and the reasoning behind each design — in ai-automation-workflows.
lego-backend — text or image to a buildable LEGO set Takes a prompt or an ordinary photo and produces a complete mosaic kit: quantises the image to the closest real brick colours, matches them to actual parts against a bundled Rebrickable catalogue, and emits a parts list, colour map, height map, section maps and step-by-step PDF instructions. The constraint that makes it interesting is that the palette is not free — it is whatever LEGO actually manufactures. 2D input yields a mosaic; a 3D mesh yields a 3D build.

Ten years as a senior data analyst across telecom and government network operations — Ministry of Interior Qatar, Nokia, Telenor, Ufone. Built and owned the pipelines behind national network performance data: ingesting and cleaning large multi-source telemetry, then applying Python, SQL and machine learning to detect degradation and surface anomalies. Supported network readiness for the FIFA World Cup 2022 and AFC Asian Cup 2023.
