Projects
Things I've built.
Offline-First AI System
Field and emergency use AI system designed for zero-connectivity environments. Features Arabic language support, offline RAG, speech-to-text, and vector search. Runs local LLMs via Ollama — Qwen (1.8B, 7B) and DeepSeek (1.3B, 7B) — with custom parameters for context length, temperature, and memory constraints optimized for edge hardware.

- Ollama
- Qdrant
- FastAPI
- Whisper
- Node.js
Handwritten prescription OCR API — upload an image, get back drug name, dosage, frequency, and prescriber as structured JSON. Pipeline runs TrOCR for handwriting recognition, fuzzy-matches drug names against the FDA NDC dictionary, and uses Flan-T5 for field extraction. Includes a LoRA fine-tuning pipeline via PEFT that trains only ~0.47% of parameters.

AreWeOkay 💔
In ProgressAI powered relationship text analyzer. Paste any message from your partner and find out if you are actually okay — or if you should start preparing yourself. Powered by BERT fine tuned on real relationship data sourced from Reddit and HuggingFace emotion datasets. Built with PyTorch, HuggingFace Transformers, FastAPI, and Streamlit to detect four danger levels: Safe, Suspicious, Danger, and It's Over.

Freelance & Consulting
Buy me a coffee ☕
Or better yet — hire me for a project. I take on a small number of freelance engagements at a time. If the problem is interesting, I'm probably in.
Fractional Tech Lead
Need a senior engineer to own architecture decisions, mentor the team, and ship — without a full-time hire? I slot in, raise the bar, and leave the codebase better than I found it.
Let's talk architecture →Backend & API Engineering
From zero to production-grade. REST APIs, background queues, database design, caching layers — I build backends that don't fall over at 3am.
Get a solid backend →AI Integration & Pipelines
RAG pipelines, LLM integration, local models, prediction systems — I turn AI from a buzzword into a working feature inside your product.
Add AI to your stack →SaaS Product Build
Got an idea and need someone to build the whole thing? Full stack, infrastructure, auth, billing — end to end. From zero to launched.
Build my SaaS →Not sure what you need?
Just email me. We'll figure it out over a (virtual) coffee.
