01 · Experience

Where I've worked

Sep 2026 – Present

Software Engineer · Technosoft Inc.

Part-time · Beirut

Automating repetitive engineering design and modeling work with the Adaptive Modeling Language (AML). I apply object-oriented design and computational geometry to engineering problems, working directly with engineers to turn their workflows into software.

Software Engineering Intern · Technosoft Inc.

Beirut

Built parametric, geometry-driven models for engineering workflows in AML. Converted to a part-time engineering role at the end of the internship.

Aug – Sep 2025

Software Developer Intern · Fusion Compliance Technologies

Backend · .NET

Built layered C# applications following Clean Architecture with EF Core, LINQ and SQL Server, and maintained RESTful ASP.NET Web APIs with strict validation for reliable, consistent data.

Full-Stack & Optimization Intern · The UCTP Project

University course timetabling

Designed a 14+ table PostgreSQL schema for faculty workload and scheduling, wrote a MiniZinc engine that generates conflict-free timetables, and shipped the full-stack platform around it in Node.js and Express.

Things I've built

Featured · Senior project In progress

Yalla

A mobile app that maps nearby places and helps friend groups agree on when and where to meet.

  • Built the Friends system end to end: requests, people search, groups and "who's free" views, on FastAPI with Postgres Row Level Security.
  • Map search as you type, place details, user-submitted places and a time-voting screen for plans.
  • Protected branches with CI running analysis, unit tests and database security-policy tests on every PR.
  • Next: a fine-tuned Qwen3-0.6B intent parser, a LightGBM activity ranker and a calibrated attendance model.

Optimization · 2025

UCTP Scheduler

Course timetabling for a whole university. The solver turns hard constraints into a week with zero clashes.

  • MiniZinc model covering faculty workloads, room availability and course assignments.
  • 14+ table PostgreSQL schema for faculty workload and scheduling data.
  • Full-stack platform in Node.js, Express and EJS, with course and room views per department.
