Project details
You will get a scalable, production-ready Python-based AI application or MVP built with clean, modular architecture, RESTful APIs (FastAPI or Flask), and a modern frontend. With 15+ years of software development experience and deep expertise in AI/ML, I specialize in building full-stack solutions that integrate state-of-the-art AI models such as OpenAI GPT, Hugging Face transformers, and custom ML pipelines.
My expertise includes:
Designing and optimizing Python backend systems for AI workloads
Developing efficient API endpoints with FastAPI or Flask for low-latency model inference
Integrating vector databases like Pinecone, Weaviate, or FAISS for semantic search
Implementing secure authentication and authorization with OAuth, JWT, or Auth0
Deploying applications using Docker, Kubernetes, and CI/CD pipelines on AWS, GCP, or Azure
Optimizing PostgreSQL and Redis for fast data access and caching in AI workflows
Building intuitive frontends
Whether you’re launching an AI-powered MVP or modernizing legacy Python codebases, I’ll ensure your app is scalable, maintainable, secure, and production-ready, designed to handle growing user demands and evolving AI capabilities.
