AI & LLM Engineer · Agents, RAG, Observability, MCP, Multimodal AI, Efficient Language Models

Portfolio · LinkedIn · Email

I build AI systems end to end — from retrieval and agent orchestration to evaluation, observability, tool interfaces, and developer workflows. My recent work focuses on production-minded LLM applications, multimodal agents, MCP infrastructure, and resource-efficient language models.

I like taking ambiguous problems, turning them into working systems, and then making the systems easier to inspect, evaluate, and improve. The interesting problems aren't the ones with clean benchmarks; they are the ones where latency, evaluation, and reliability decide whether a model actually ships or just demos well.


Open Source Contributions

Repository Stars Pull Request Description
The-PR-Agent/pr-agent ⭐ 13.2k #3736 Prepared and normalized outgoing comment bodies in AWS CodeCommit provider before calling publish_code_suggestions to prevent AWS API payload rejection.
huggingface/accelerate ⭐ 9.9k #4296 Fixed a critical checkpoint resumption regression where skip_first_batches dropped drop_last, non_blocking, slice_fn, and mesh parameters during distributed DataLoader reconstitution.
Agenta-AI/agenta ⭐ 4.8k #5377 Fixed logging keyword argument typo (exc_infp → exc_info) in authentication service that swallowed exception stack traces during auto-join failures.
taylorwilsdon/google_workspace_mcp ⭐ 3.3k #1190 Allowed Google Chat send_message MCP tool to send plain text messages without triggering strict union schema validation errors on unused optional fields.
taylorwilsdon/google_workspace_mcp ⭐ 3.3k #1189 Fixed Google Forms tool creation by mapping title to documentTitle and applying form descriptions through subsequent batchUpdate calls.
taylorwilsdon/google_workspace_mcp ⭐ 3.3k #1155 Normalized input attendee dictionaries into valid Google Calendar API v3 structures, preventing 400 Bad Request exceptions on event creation.
pydantic/pydantic-settings ⭐ 1.5k #982 Resolved platform-specific static type checking error on Windows (mypy --platform win32) by safely guarding Path.is_mount attribute resolution.
qdrant/qdrant-client ⭐ 1.4k #1493 Enforced UpdateMode semantics in Qdrant Local client batch updates and prevented operations on deleted points from reviving ghost points.
Lightning-AI/litData ⭐ 615 #928 Fixed streaming dataset checkpoint state synchronization by resetting wrapper sample and cycle counters upon reset_state_dict.
