I've built production-ready Python services for Parallel Solutions, including a Django document-generation platform that creates Word reports and Excel exports from Markdown templates. I integrated OpenAI, DeepSeek, and Qwen APIs to automate document analysis, classification, data extraction, and analytical reporting.

I built a RAG assistant using DeepSeek and FAISS, with document loading, chunking, all-MiniLM-L6-v2 embeddings, contextual generation, MD5-based caching, and strict prompting. I also designed PostgreSQL schemas and complex SQL queries that improved service performance by 10%.

At Akatosphere, I maintained a Django backend connected to a React frontend through REST APIs and WebSockets, extended Django REST Framework endpoints, maintained Swagger/OpenAPI documentation, and wrote pytest unit and integration tests. At SMAIPL, I developed and debugged AI chatbots using multiple LLMs, improving response logic, integrations, scalability, and reliability.

I've delivered end-to-end projects ranging from recipe and review platforms to a FastAPI charity-donation API and a Telegram status-notification bot. I enjoy turning ambiguous requirements into scalable, well-tested APIs, improving legacy systems, automating workflows, and supporting junior developers through code reviews and pair programming.
