Software engineer / Cloud-native builder

5+ years making systems faster, cleaner & easier to scale.

I turn complex business requirements into reliable production systems—from system design and APIs to frontend experiences, cloud deployment, observability and production support.

01 / Expertise

I help teams build better software.

My strongest focus is Java backend engineering, supported by full-stack, cloud, DevOps, distributed systems, data and AI capabilities.

01

Backend & Microservices

My strongest lane

Java 8/17/21, Spring Boot, Spring, Hibernate/JPA, Kotlin, REST, SOAP, GraphQL, gRPC, WebSockets, concurrency, caching and resilient distributed-service design.

02

Cloud-Native Engineering

Build → deploy → monitor

AWS, Azure, Docker, Kubernetes, Jenkins, Maven, Gradle, GitHub, CI/CD, infrastructure-aware design and production observability.

03

Modern Full Stack

End-to-end delivery

Angular, React, TypeScript, JavaScript, RxJS, responsive UI, reusable components, frontend-backend integration and automated testing.

04

AI-Enabled Applications

Emerging differentiator

Python, retrieval-augmented generation, embeddings, vector databases, prompt engineering, AWS Bedrock and intelligent enterprise search experiences.

Good engineering

takes time

and the right systems

save it.
