What I'm looking for

I'm looking to build secure, scalable cloud-native systems and high-performance APIs, with opportunities to work on microservices, event-driven architectures, and reliable production platforms.

I've built production microservices at GlobalTech Institute and Lead Tech Institute, including data extraction and transactional email platforms. My work has delivered scalable ingestion, messaging, and real-time processing workflows using FastAPI, Celery, Redis, RabbitMQ, Kafka, and AWS.

I focus on secure, resilient systems: encrypted credentials, schema-drift detection, idempotency, retries, delivery tracking, authentication, rate limiting, and fault-tolerant execution. I bring over four years of full-stack engineering experience building high-performance APIs with cloud-native and event-driven architectures.
