What I'm looking for

I’m looking to build scalable backend systems and ship LLM/RAG features in production—owning architecture, performance, and CI/CD. I want a collaborative team (Agile/Scrum) where I can translate ambiguous requirements into reliable, user-ready products.

I’m a Senior Software Engineer with 5+ years of experience building scalable backend systems in Python. I focus on high-performance APIs, multi-tenant SaaS platforms, and production-grade systems that stay reliable under load.

At InvoZone, I architected and scaled services using Python, Django, DRF, FastAPI, and Flask—supporting thousands of concurrent requests with low latency. I also designed and deployed RAG pipelines with FastAPI, FAISS/Chroma, and OpenAI embeddings to enable intelligent document search, clinical data analysis, and automated Q&A.

I build products that reduce operational burden: I developed a Twilio-based WhatsApp AI Support Bot integrating retrieval models with GPT-4, automating >60% of support queries and cutting team workload by 35%. I improve maintainability through Onion/Clean Architecture and strengthen performance by optimizing PostgreSQL/MySQL schemas, indexing, and Redis caching—reducing slow queries by ~30–40%.

My work spans AI-driven applications and learning platforms, including OpenAI GPT-based lesson generation and adaptive assessment engines at AILA. I enjoy collaborating across AI/ML, frontend, QA, and DevOps teams in Agile/Scrum, turning ambiguous requirements into architecture plans, estimates, and backlog-ready user stories.
