At CodeHaste, I own the booking domain from system design through production monitoring for a B2C platform processing 10,000+ daily transactions. I build TypeScript and Node.js services with NestJS and PostgreSQL, including scheduling workflows where data integrity and correctness matter.
I rebuilt authentication with AWS Cognito and OIDC-compatible flows, reducing redundant authentication calls by 60%. I also added RBAC and multi-tenant authorization, and used Redis caching and query optimization to keep API latency stable under load.
At CodeHaste, I migrated a monolithic workflow to event-driven services using Kafka and AWS SQS, with Docker-based deployment and CI/CD. I also built a multi-job booking engine that supports overlapping and standalone appointments, eliminating manual job entry.
At KingpiN Vision Forge, I own engineering and ship customer-facing products across the stack. One live multi-tenant School Management Platform serves 100+ daily users; I also built production integrations at Zluri Technologies and REST APIs and database schemas at BTrees Technologies.
