What I'm looking for

I’m looking to build production-grade backend and AI/RAG services where reliability, performance, and observability matter—using agentic systems, APIs, and automation to deliver measurable business impact.

I’m a Software Engineer focused on shipping production backend services powered by AI, RAG, and agentic workflows. At Reewild, I migrated Cosmos DB from provisioned throughput to serverless billing, cutting database infrastructure cost by 98% with zero downtime, and I architected a campaign analytics service with an integrated vector database layer for semantic product matching that helped unlock enterprise deals.

I’ve also built pragmatic AI tools and systems through internships and project work: an autonomous, LLM-powered marketing AI agent that accelerates ideation turnaround, an AI-powered data management tool using Bing Image Search API, and backend APIs for automated raffle winner selection while reducing stale entries. On the engineering side, I integrated Redis caching into Django ORM paths to boost data retrieval by 15%, and I built a ChatGPT-powered Flask Slack bot to automate team workflows. In my portfolio projects, I delivered a production-grade RAG backend (OmniDoc) with hybrid retrieval and agentic reasoning, and a webhook-driven GitHub intelligence API (PulseBoard) that combines deterministic scoring with LLM-based evidence-backed improvement plans.
