I am a software engineer focused on backend systems, distributed architectures, APIs, and data-intensive applications. I enjoy building production-oriented software ranging from AI-powered search platforms and analytics systems to workflow automation tools and scalable backend services.

My work spans system design, database optimization, background job processing, caching strategies, API development, and fault-tolerant architectures. I primarily work with Python, TypeScript, PostgreSQL, Redis, FastAPI, Node.js, and modern cloud infrastructure.

I also actively contribute to open source, focusing on backend frameworks, API tooling, and developer productivity platforms.

• Patched an asynchronous lifecycle state leak by provisioning isolated session managers per runtime cycle, eliminating task-group failures in multi-run test suites. [PR]
• Hardened token validation pipelines using thread-safe model replication to prevent cross-request state pollution while propagating identity claims across service boundaries. [PR]
• Resolved OpenAPI-to-JSON Schema compatibility issues, protecting autogenerated client SDKs from runtime failures. [PR]

Tech Stack: FastAPI, Pydantic, OAuth2/JWT

• Architected a distributed retrieval platform coordinating 5 external services and queue-backed workers processing 14 concurrent jobs with retries and fault-tolerant recovery across search, retrieval, and LLM generation stages.
• Reduced redundant retrieval workloads through multi-layer Redis caching (1-hour query TTL, 24-hour content TTL), while implementing query rewriting, response streaming, citation validation, and multi-turn AI workflows.

Tech Stack: TypeScript, Node.js, Express.js, Redis, BullMQ, PostgreSQL, Supabase, React, Docker, Nginx

• Integrated 4 external service APIs while enforcing 5-second timeout boundaries and graceful fallback handling for external failures.
• Built a server-side rendered application with layered validation and structured logging to improve reliability and maintainability.

Tech Stack: Django, Python, Requests

• Developed secure session-based authentication and request validation layers to protect application data integrity.
• Optimized feed retrieval from O(N) relational round-trips to O(1) query execution using relationship prefetching and database annotations.

Tech Stack: Django, PostgreSQL, REST APIs
