Hi, I'm Omkar Wagholikar a software engineer working on backend systems in C#, where I optimize application logic, debug distributed workflows, and build scalable document ingestion pipelines on cloud infrastructure.

My day-to-day toolbox includes Python, Java, JavaScript/TypeScript, and C#, with meaningful experience across Django/DRF, React, Node.js, Celery, and RabbitMQ, along with data tooling like Airflow, DBT, BigQuery, and Elasticsearch. I'm comfortable across both application and data engineering from building full-stack platforms and scalable ingestion systems to authoring BRAGS, a published Python package for customizable on-device RAG pipelines with a Go-based file watcher and an MCP server for Claude Code. I also enjoy exploring lower-level programming in C, Rust, and SIMD/AVX2 to better understand performance and concurrency.

Beyond engineering, I'm a passionate reader, astronomy enthusiast, and occasional graphic designer and photographer. I actively contribute to open source, compete in hackathons, and speak at developer communities most recently on Unix file descriptors and PTY internals at FOSS United Pune.

I'm always excited to connect, collaborate, create or just chat about exciting tech stuff
