Hesam Jaferi
I’m a Senior Full-Stack & AI Engineer with 10+ years of hands-on experience building and shipping production software, with a strong focus on Python, AI/LLM applications, backend systems, and modern web products.
I specialize in turning AI ideas and complex product requirements into working, production-ready applications—from LLM-powered agents and automation workflows to API platforms, data-intensive systems, and full-stack applications.
My core stack is Python, FastAPI, Django, React, TypeScript, PostgreSQL, Docker, and Kubernetes. I work across the entire product stack: backend architecture, REST APIs, AI/LLM integration, data processing, databases, frontend development, third-party integrations, testing, deployment, and production troubleshooting.
I’ve built and shipped serverless AI platforms, agentic applications, payment systems, digital identity platforms, real-time data pipelines, operational dashboards, and cloud-native services. I’m comfortable joining an existing codebase, understanding unfamiliar systems quickly, implementing features without unnecessary rewrites, and fixing difficult production problems.
I bring strong systems and infrastructure experience as well, including distributed systems, asynchronous processing, cloud deployment, CI/CD, Kubernetes, and Rust. This allows me to solve problems beyond the application layer when reliability, performance, or scalability becomes important.
I’m a hands-on senior engineer rather than a management-only architect. I can take a feature from requirements → architecture → implementation → frontend → deployment → production, while keeping the codebase maintainable and the solution focused on the actual product goal.
I’m available for remote contract and long-term engagements, particularly with teams building AI products, SaaS platforms, developer tools, and data-driven applications.
