What I'm looking for

I want to architect high-performance, resilient, maintainable enterprise systems—building microservices on Java and AWS, modernizing platforms, and shipping secure products that support document automation and intelligent search.

I’ve been working as a Solutions Architect at Freelance since Jan 2018, building scalable, secure, cloud-native enterprise applications across FinTech, digital lending, document management, tax & compliance, smart metering, and AI-powered knowledge management.

I architect microservices-based solutions using Java, Spring Boot, and Spring Cloud on AWS, with hands-on work in Docker, Kubernetes, and CI/CD automation and DevOps practices.

I’ve helped deliver products like Click Loan (loan origination), SafeVault (secure document management), TaxFlow (tax processing & compliance), and AI-powered RAG platforms for intelligent search, workflow automation, and cloud-scale deployment—alongside API design, system integration, cloud migration, and performance optimization using PostgreSQL, Redis, and Elasticsearch/OpenSearch with Keycloak and React/React Native.
