Avinashbhai O.

I’m a Senior Python Backend & AI Engineer with 10+ years of experience building scalable backend systems, SaaS platforms, APIs, cloud applications, and AI-powered solutions. I help businesses turn complex requirements into reliable, scalable, production-ready software. My strongest areas are Python backend development, system architecture, API development, AI integrations, Computer Vision, and cloud deployment. What I can help you build • Scalable backend applications using Python, Django, DRF, FastAPI, and Flask • REST APIs and third-party API integrations • SaaS and multi-tenant platforms • Backend architecture for new or existing products • AI-powered applications and intelligent automation • Computer Vision and real-time video analytics systems • Object detection using YOLO and OpenCV • Face recognition and smart monitoring solutions • LLM and RAG-based applications • AI voice and conversational systems • Background processing using Celery, Redis, and RabbitMQ • PostgreSQL/MySQL database design and optimization • Dockerized applications and CI/CD pipelines • AWS deployment and production infrastructure • On-premise and edge AI deployments • Performance optimization, debugging, and backend modernization Core Technologies Backend: Python, Django, Django REST Framework, FastAPI, Flask Databases & Processing: PostgreSQL, MySQL, Redis, Celery, RabbitMQ AI & Computer Vision: OpenCV, YOLO, Face Recognition, Video Analytics, LLMs, RAG, AI Automation Cloud & DevOps: AWS, Docker, Linux, Nginx, GitHub Actions, CI/CD How I work I focus on understanding the business problem first, not just writing code. Before implementing a solution, I consider: • Architecture and scalability • Performance and reliability • Security and maintainability • Database and API design • Deployment strategy • Long-term development requirements I’m comfortable working on both new products from scratch and existing production systems that need improvement, optimization, new features, or AI capabilities. My goal is simple: Build software that works reliably in production, scales with the business, and solves the actual problem.
