What I'm looking for

I seek roles building scalable SaaS/cloud systems where I can own architecture, improve performance, mentor engineers, and work in Agile teams with strong DevOps practices.

I am a full-stack software engineer with 3+ years of experience building SaaS, B2B, and B2C platforms using JavaScript/TypeScript, React, Next.js, Nest.js, Node.js, and AWS. I have delivered production systems with scalable architecture, large-file streaming, CI/CD pipelines, and optimized APIs while mentoring junior engineers and interns.

I have led end-to-end projects including a full-stack SaaS platform, a tutoring platform for 1,000+ users, and multiple contract projects, and I solved 500+ coding problems on leading platforms. I work well in Agile teams, prioritize maintainable code and performance, and seek roles where I can contribute to architecture, cloud infrastructure, and team growth.
