I help teams build and improve Python backends for SaaS products and growing platforms, whether that means starting an MVP from scratch, integrating AI capabilities, or improving an existing production system. Most of my work involves owning backend systems: reviewing code, fixing performance issues, migrating services, designing scalable APIs, and making sure applications stay stable as they grow. I mainly work with Python, Django, FastAPI, Flask, and AWS, while selecting the right architecture and tools based on the actual business problem and computer vision solutions for image processing, detection, and AI-based analysis and AI/ML integrations including LLM applications, RAG pipelines, NLP systems, and intelligent automation. 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, integrating AI/ML solutions, and handling the important engineering 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 REST API development and third-party integrations Code reviews, refactoring, and performance optimization Databases like PostgreSQL, MySQL, and MongoDB Background jobs with Celery, Redis, and RabbitMQ Deployments and scaling on AWS AI/ML integrations including LLM applications, RAG pipelines, NLP systems, and intelligent automation Computer Vision solutions for image processing, detection, and AI-based analysis 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: Healthcare backend handling patient data, appointments, and AI-powered diagnostics.

I build backend APIs in Python — clean, working endpoints your app or frontend can rely on. Most of my work is REST APIs with Django and FastAPI, and I'm comfortable taking a feature from the idea to a working endpoint. What I can help with: REST APIs — building and extending APIs with Django REST Framework or FastAPI: clear endpoints, validation, error handling, and documentation. Database work — PostgreSQL and MySQL: designing tables, writing queries, indexing, and migrations. Practical data work that fits what you're building. Integrations — connecting third-party APIs and services into your backend: payments, external APIs, webhooks. Background tasks — Celery and Redis for jobs that run in the background, like emails, exports, or scheduled work. Fixing and extending — picking up an existing Django or FastAPI project, adding features, or cleaning up messy code without breaking what already works. I'm a good fit for: - New APIs, or adding endpoints to an existing backend - Smaller or well-defined backend tasks you want done properly - Extending or fixing a Django/FastAPI project - Clean code you or your team can build on later I keep things simple and do the task properly. Tell me what you need and I'll help you get it working. Tech: Python, Django, FastAPI, PostgreSQL, MySQL, Redis, Celery, Docker
