Backend Developer | FastAPI, Python, AWS | AI & LLM Engineer

Backend Developer and AI & LLM Engineer with 4+ years of experience, working as an independent consultant under SA Technologies (Hyderabad, India) since 2024. VIT graduate.

I design and build production backends, AI products and automation for clients — from MVPs to hardened, deployed systems. My core skills: Python, FastAPI, React, TypeScript, PostgreSQL, AWS, Docker, REST APIs, and LLM/AI integration (OpenAI, Gemini), plus workflow automation.

Recent work includes a multilingual AI calling-agent platform (FastAPI services orchestrating speech recognition, LLM function-calling and live telephony), a script-first AI video-editing product (FastAPI backend turning scripts and raw clips into an edit decision list, with a React review interface), and an AI tuition platform with a Socratic AI teacher that adapts practice to each learner.

I work remotely with international teams and communicate in clear written English. Portfolio: https://sa-technologies-umber.vercel.app/
