What I'm looking for

I seek a role building scalable backend systems and integrations, with strong engineering ownership, cloud-native tooling, and opportunities to mentor and improve platform performance.

I am a software engineer with strong expertise in building and maintaining scalable REST APIs and microservices, with hands-on experience across AWS, GCP, Kubernetes, and Docker.

At Eastvantage (Solutions30) I refactored legacy features and reduced processing time by around 90% through adoption of message queues and ORM, provided full production support for owned features, and integrated systems for external clients.

Previously at Pez.AI I deployed services to cloud platforms, configured microservices on Kubernetes, implemented RESTful endpoints, automated manual processes with scripts and jobs, and contributed to data extraction and transformation projects while mentoring new hires.

Earlier experience as a data analyst included building VBA automation, generating medical and KPI reports for hospital quality management, and presenting analyses to executives. I bring a results-oriented approach, strong collaboration with product owners, and a focus on performance and reliability.
