Hi! I'm a Python Developer from Bangladesh. I've completed my Diploma in Computer Technology. I've been working with Python for over 5 years, building useful software for others and expanding my knowledge. On the side, I code a bit in ASM and C. Here are a few key points about me: • I'm experienced in Python-Requests, Selenium, QT5, BS4, Flask, and SQL. • I can build GUI, multi-threaded, reliable and performant desktop/server applications. • Scalable and fault-proof backend application. • I've completed over 150 small to medium projects as a freelance developer since 2022.

Python and Django developer specializing in REST APIs, FastAPI backends, and ChatGPT and OpenAI integrations, building web applications that go from idea to production without cutting corners. Core stack: Django, FastAPI, DRF, PostgreSQL on the backend, React and Next.js on the frontend, OpenAI, LangChain, and Pinecone on the AI side. Python and Django developer with 10+ years building REST APIs, SaaS backends, and ChatGPT-powered applications using OpenAI, FastAPI, and LangChain. Most clients come to me for one of two things, they need a solid Django or FastAPI backend built properly, or they want to add AI features like ChatGPT, LLM pipelines, or automation into an existing product without it becoming a mess. I've done both enough times to know what works. I take projects from idea to deployment. Clean API design, solid database work, third-party integrations, and AI built into real products, not demos. Recent work: ✅Built a SaaS platform in Django + React serving 10K+ monthly users ✅Added a context-aware ChatGPT chatbot into an existing Django app using OpenAI and LangChain without rewriting the backend ✅Built a RAG pipeline with FastAPI + Pinecone that replaced a manual research workflow, saving the team hours every week ♦️Backend: Django, FastAPI, DRF, Celery, REST API, PostgreSQL, Redis, JWT/OAuth ♦️Frontend: React, Next.js, TypeScript, TailwindCSS ♦️AI & LLMs: OpenAI API, ChatGPT, LangChain, Pinecone, FAISS, RAG pipelines, Model Evaluation ♦️DevOps: Docker, GitHub Actions, AWS, DigitalOcean Clear communication, honest timelines, and code the next developer can actually read. If you need a Python developer who understands both backend engineering and AI send me a message. I'm just a text away.
