What I'm looking for

I seek roles building scalable backend and microservices systems, with DevOps practices, collaborative agile teams, mentorship opportunities, and measurable performance impact.

I am a Senior Software Engineer with over 8 years of experience building scalable microservices-based solutions using Go and Java, with strong DevOps expertise in CI/CD, Docker, Kubernetes and AWS. I have a proven track record of resolving production issues, optimizing performance (including JVM tuning and memory profiling), and improving system reliability through testing, code reviews and secure authentication integrations.

My accomplishments include resolving hundreds of bugs, reducing latency dramatically through microservice enhancements, leading full-stack ERP development for hundreds of users, and managing donation platforms that processed over 10,000 contributions. I thrive in collaborative, agile teams where I can mentor engineers, drive best practices, and deliver measurable business impact.
