Hi. I’m a backend engineer focused on production APIs, data/security, and AWS deployments, with a strong Python backend + AI/ML background and experience integrating systems end-to-end (API design, auth, DB, monitoring, and reliability). For Inboxlogy, I can help you ship new backend modules by: - Designing clean REST endpoints + service-layer business logic - Working with MongoDB (schema design, indexing, performance tuning) - Implementing auth/authorization and secure data handling - Deploying/operating services on AWS (logs, alarms, rollbacks, cost-aware setups) - Coordinating closely with React front-end for smooth API contracts While my primary stack is Python, I’m comfortable working in an existing Java/Spring Boot codebase and can ramp quickly. If helpful, I can start with a small paid trial feature (1 endpoint + tests + docs) to prove fit, then proceed milestone-by-milestone. Best regards, Viglundur
