At Balboa IM, I built a Rust hybrid search engine as personal work, demonstrated it, and had it integrated into the product. It combines BM25 and fuzzy lexical retrieval with ONNX embedding search, runs fully offline, and is called by the Deno backend through a C-ABI FFI boundary.

For codeforces-mcp, I published an MCP server that gives coding agents access to Codeforces practice data through six read-only tools. I built a testing harness with fixture-backed contract tests, opt-in live tests for API drift, and agent-behaviour evaluations, all gated in CI.

My projects also include ZenLearn, where I gated generated code with sandboxed syntax checks and unit tests, and my KUET undergraduate thesis, LiteHand3D. For the thesis, I distilled a ViT-H teacher into a ViT-S student and shipped a real-time streaming service; ONNX int8 quantization reached 24.5 FPS on CPU while retaining accuracy.
