Full Stack Software Engineer specializing in secure, high-performance microservices and data-driven AI.
United StatesWhat I'm looking for
I’m a Full Stack Software Engineer with 7+ years of hands on experience building mission critical systems at scale, delivering products that impacted millions of users across fintech, energy distribution, and education. I specialize in Java and Kotlin, architecting high performance backend systems with Spring Boot microservices, distributed systems, and secure API design for enterprise customers.
I’ve architected and developed Java backend microservices for mission critical, global-scale transaction processing using Spring Boot. I optimize database performance and query execution, lead CI/CD pipelines for reliable deployments, establish monitoring and alerting for rapid issue resolution, and mentor engineers through thorough code reviews and system design guidance.
I also accelerate customer onboarding and operational efficiency by improving authentication and system architecture—implementing modern authentication mechanisms and driving refactoring, reusable UI/component libraries, and complex database schema migrations. Guided by Agile practices, test driven development, and strong code quality standards, I’ve delivered secure OAuth/JWT-based access, production-safe migrations, and dependable delivery timelines while bringing my Master of Data Science (AI and Machine Learning) mindset to data-driven decision making.
