My name is Ognjen Marceta. My friends call me Ogi.
Senior Software Engineer with 15+ years of experience building scalable web and mobile products across SaaS, fintech, smart access, device management, and game development.
My strongest value is turning complex product and technical requirements into reliable, maintainable systems. I work across frontend-heavy and full-stack environments, with deep experience in JavaScript, TypeScript, Vue, React, Node.js, software architecture, refactoring, and product delivery.
Over the years, I’ve contributed as both a hands-on engineer and technical lead — building core product areas, improving performance, shaping architecture, mentoring teammates, and helping teams ship with confidence.
I’m especially strong in:
- Scalable SaaS and product engineering
- Frontend/Backend architecture and system design
- JavaScript / TypeScript application development
- Refactoring and modernization of existing systems
- Reusable patterns, internal tooling, and maintainable codebases
- Translating ambiguous requirements into production-ready solutions
- Cross-team collaboration, mentoring, and technical leadership
I care about building software that is not only functional, but clear, scalable, and valuable for the people using it.
Always open to connecting with people who enjoy building great products, solving hard problems, and improving how teams deliver software.
