• 10+ years of Software Engineering experience, with a proven history of leading technical squads, architecting, and building complex transactional backend systems.
• Expert mastery of Python (FastAPI, Django) and proficiency in modern Front-end frameworks (Angular/Typescript).
• Deep mastery of RESTful API design, specialized in Tool-Calling patterns and structured data exchange for LLMs.
• Strong SQL skills (PostgreSQL/MS SQL) and production experience with OAuth2/JWT for secure service-to-service communication.
• Experienced in working with cloud platforms (GCP, AWS) and deploying containerized services that are secure and scalable.
