BUILDER · BEIRUT · 2026
I am Hadi Diab, a full-stack developer. I build the backends, the interfaces, and the operational pieces that have to keep working on a Monday morning.
Personal work, mostly developer tools. Three featured below have their own write-ups; the rest link out to the source.
DEVELOPER TOOL · 2026
A read-only MCP server giving AI agents safe schema discovery and query access across SQL Server and Postgres, with profile isolation that prevents cross-environment leaks.
TypeScript · Node.js · MCP · PostgreSQL · SQL Server
AI TOOLING · 2026
An open-source MCP server that lets AI agents drive real Figma work, frames, auto layout, components, through a validated bridge into the plugin sandbox.
TypeScript · Node.js · MCP · WebSockets · Figma Plugin API
REAL-TIME · 2024
A scalable chat backend on Fastify and WebSockets, using Upstash Redis Pub/Sub to broadcast across instances, with Docker multi-stage builds and graceful shutdown handling.

Work shipped under contract. Client names stay private; the architectural decisions do not.
CLIENT WORK · REGULATED FINANCE · 2026
An exam platform for a regulated-finance compliance advisory: outbox events and a Postgres-only job queue, pgvector and OpenAI for author-time question similarity, and a five-state compliance model that drives the right escalations.
TypeScript · React · Express · PostgreSQL · Prisma · pgvector · OpenAI · Authentik
Two roles, both since 2024. The thread is ownership: writing software end-to-end and being on the call when something breaks.

JUL 2024 – PRESENT
Beirut, Lebanon
Carrying a multi-tenant shipment platform end-to-end, with side work spanning a real-time food-delivery backend, a queue-based ERP invoice integration, a Dahua DSS camera bridge, and a multi-tenant agentic customer-support platform on LangChain and LangGraph.

APR 2024 – JUL 2024
Remote
A three-month stint building queue-based, Pulumi-driven EC2 provisioning so LLM workloads could spin up on demand without breaking the running fleet.
About
Beirut, late nights, a laptop, and a habit of reading the documentation before I touch the keyboard. I am a full-stack developer at Pixel38, where I own a shipment platform end-to-end and spend a fair amount of my week on the phone with clients explaining what is and is not worth building. I care about software that keeps working after the launch event, the kind that does not need a postmortem when the marketing team finally tweets about it.
Contact
If you have a system that needs to be built well, or you are looking for a full-stack developer who finishes what he starts, send me a note. I read every email and reply to most within a day.
