I help teams build and improve Python backends for SaaS products and growing platform, whether that means starting an MVP from scratch or jumping into an existing codebase and making it better. Most of my work involves owning backend systems: reviewing code, fixing performance issues, migrating services, and making sure things stay stable as the product scales. I mainly work with Python, Django, FastAPI, and AWS, and I choose tools based on what actually fits the problem. Moreover, I have been working as a Python developer for 8+ years, supporting real production systems across different industries. I’m comfortable building new features, cleaning up legacy code, and handling the unglamorous but important work that keeps systems reliable. What I usually work on: Python backends using Django, FastAPI, and Flask SaaS platforms & MVPs (early builds → production) Microservice migrations and backend restructuring Code reviews, refactoring, and performance tuning APIs used by React and other frontends Databases like PostgreSQL, MySQL, and MongoDB Background jobs with Celery, Redis, and RabbitMQ Deployments and scaling on AWS Practical AI/ML features (NLP, chatbots, LLMs) when they make sense Key Projects: Touringery: Multilingual tour booking APIs → improved booking throughput by 50%. Moeving EV: Fleet tracking microservices → real-time data processing for 500+ vehicles. Kera Health: Backend for patient data, appointments, and AI diagnostics. Healthcare AI Diagnostics: Integrated ML models for automated patient reporting. Chatbot & NLP: Built intelligent NLP pipelines for customer support and internal knowledge management. I work well independently or with a team, communicate clearly, and take responsibility for the backend parts I touch. I’m available 40+ hours per week and can overlap with US and European time zones. If you’re looking for someone who can step into your backend and take ownership, "just click Invite", I usually reply within a few hours.
