What I'm looking for

I’m looking for a high-velocity team where I can prototype fast, deliver pixel-perfect features, and tackle complex architecture and performance challenges—while maintaining stable, production-ready releases through pragmatic, autonomous engineering.

I’m a Senior Software Engineer with a versatile background in building and scaling products from seed-stage to global platforms. I’m hands-on across modern Frontend (Vue, React) and robust Backend (Java, Kotlin), and I thrive in high-velocity startup environments where speed and quality have to coexist.

At Lightspeed, I architected and executed a strategic performance overhaul for the site builder—reducing asset overhead and optimizing initial rendering speeds. I led large-scale refactoring to decouple architectural dependencies, implement advanced code-splitting strategies, and improve stability and developer experience, while also establishing high-integrity Design–Engineering delivery workflows.

Previously at Instaloper, I engineered full-stack solutions for a medical SaaS startup, taking a lead role in frontend development and UI/UX design with Kotlin, React.js, custom REST APIs, and Spring Security authentication. Earlier at ELG LLC, I headed the technical division as Principal Engineer and later led a team of four Java developers, boosting productivity by 30% through coaching, streamlined workflows, and rigorous code reviews.
