Software Engineer at Martian
Apr 2024 - Jul 2024 (4 mos)

The main Martian feature is an LLM router: a user can send a prompt, and the Martian’s model will decide on the best LLM for it. I contributed to Martian’s adapters (github.com/withmartian/adapters). It interfaces with a large set of open and proprietary Large Language Models (LLMs). I developed a Sales Dashboard (front and backend) to give the Sales Team insights into our customers. This dashboard used HTMX/Jinja for frontend and Litestar, Pydantic, MongoDB for the backend.

We assembled an entire smart traffic light (STL) that can sense streets using cameras and act (open/close) autonomously. When I led software engineers, we created a STL hardware and software controllers, traffic simulators for traffic optimization, and dashboards.
-
We created a traffic simulator using SUMO (Simulation of Urban MObility) Our main algorithm on this simulator had 200% to 400% waiting time optimization on light to medium vehicle traffic. We also deployed our STL in four real crossing roads. To achieve this, we had to do researches in traffic optimization area by using smart traffic lights, design and develop optimization algorithms for smart traffic lights, design and create an embedded distributed real-time systems for the STL with a microservice architecture.
