Message

At Joincube, Inc., I developed FastAPI and Node.js services for transactional business workflows, separating routing, business logic, and persistence into testable modules.

I implemented idempotent requests and moved long-running work into background jobs with bounded retries and explicit task states. I also investigated PostgreSQL queries and Redis caching to address slow endpoints and stale data.

At Nectilus, I built Python services and Node.js integrations for record processing and external system synchronization. Earlier, at Syberry Corporation, I implemented REST endpoints and backend modules for business applications.
