Python Developer with 6+ years of experience building scalable backend systems, SaaS platforms, automation workflows, and AI-powered applications using python Django and modern Python development practices. ⬩ Why clients work with me: - 6+ years of Python development experience - Strong scalable backend architecture expertise - SaaS, marketplace and MVP platform experience - Clear communication and structured collaboration - Accountable for outcomes, not just code delivery - Production-ready AI + backend integrations - Long-term technical partnership mindset - Detail-oriented and committed to quality I help startups and growing businesses transform complex backend logic into fast, secure, and maintainable systems tailored for real-world products like marketplaces, CRMs, client portals, job boards, analytics platforms, and AI-driven tools. As a Fullstack Python developer, I contributed to marketplace platforms, AI-powered semantic search systems, real estate and EV comparison MVPs, loan management applications, and B2B SaaS products, focusing on clean architecture and long-term scalability. ⬩ Python backend expertise I specialize in Python Django and FastAPI backend development with PostgreSQL, Redis, and Celery, delivering production-grade solutions as a Python developer focused on scalable python development. From REST APIs and OAuth authentication flows to background workers and multi-user permission systems, I design robust backend architectures that support real growth. Whether building a B2B marketplace, SaaS MVP, or internal business platform, I approach development in a collaborative and solution-oriented way, focusing on clarity, scalability, and maintainability. ⬩ Automation and data workflows Need a system to parse thousands of PDFs, scrape e-commerce products, or monitor websites in real time? As a Python developer, I build custom scraping scripts using BeautifulSoup, Scrapy, and Selenium, paired with automation logic and APIs to feed your business engine. ⬩ AI-powered systems (LangChain + OpenAI) As a backend-focused LLM developer, I build intelligent assistants and AI-powered features using LangChain, FAISS, OpenAI, and RAG pipelines. I worked on AI-powered product catalog processing and semantic search systems, integrating LLM workflows into structured backend APIs with production stability in mind. ⬩ Architecture and deployment From scalable SaaS platforms to marketplace infrastructure, I design systems using Docker, CI/CD, and cloud deployments (AWS, Railway, Render). My work follows backend best practices, including clean architecture, modular design, security-first implementation, database optimization, and performance tuning. I prioritize reliability, clarity, and professional execution throughout every phase of a project. ⬩ What I can do for you: - Custom Django/FastAPI backends with clean architecture - REST API design and 3rd-party API integrations (Stripe, OpenAI, Twilio) - Automated scrapers, parsers, and ETL pipelines - AI and LLM integration (LangChain, Pinecone, OpenAI API, Vector DBs) - PostgreSQL schema design and query optimization - Backend architecture for CRMs, marketplaces, analytics platforms - Infrastructure setup with Docker, GitHub Actions, AWS, Railway - Post-delivery support and long-term collaboration ⬩ Technologies I work with: Python, Django, FastAPI, Flask, PostgreSQL, Redis, Docker, LLMs, LangChain, OpenAI, API, Web Scraping, BeautifulSoup, Celery, PDF/DOCX Parsing, Vector Search, CI/CD, AWS, ETL Pipelines, RAG Let’s build something that makes decisions, not noise. ⚙️ A Python developer building backend systems in production environments.
