TUHIN ACHARJEE

I'm a Software Engineer with over 2 years of experience, currently serving as Tech Lead at Rosa Technology. My core expertise lies in backend development, real-time systems, and AI/ML integration. I’ve led the development of a computer vision-based rebar detection system that improved testing efficiency by 60%, and built high-performance microservices with response times under 0.01 ms. I developed a RAG-based AI chatbot integrated with a robot and Android app, and created a Python library for precise IMU sensor calibration. I also built an LLM evaluation and observability framework using LangChain, GPT-4, and vector databases, reducing hallucinations by 30% and boosting response quality by 23%. My skill set spans Python, FastAPI, HuggingFace, FAISS, Streamlit, NLP, and system design. I’ve also worked on a Quora-based NLP project achieving 80% accuracy in question similarity prediction. I'm passionate about building scalable, AI-driven solutions that deliver real-world impact, especially in domains like robotics, fintech, and intelligent automation. I thrive in fast-paced, collaborative environments and am eager to contribute to innovative teams solving meaningful problems with cutting-edge technology.
