What I'm looking for

I'm looking to build reliable backend systems and integration-heavy services, while continuing to grow through hands-on software, hardware-software co-design, and debugging work.

I build Python backend services for API design, data intake, event-driven processing, and integration-heavy workflows. In freelance projects, I created lead-matching and Telegram delivery systems and a FastAPI PDF ingestion API that returns normalized JSON.

At Instigate Design, I contribute as a Junior Software Engineer and have worked across backend software, FPGA design and verification, and ML offloading for AIE devices. I added execution providers and operators in ONNX Runtime and supported end-to-end model flows for Text-to-Image on Strix machines.

I also developed an interpreter and tests for an open-source security-system research project, and implemented and tested C++ STL algorithms during my Instigate internship.

I work with Python, FastAPI, PostgreSQL, SQLAlchemy, REST APIs, webhooks, Docker, and Linux. I focus on clean architecture, debugging, maintainability, and reliable services.
