Senior Frontend Engineer. I've helped startups go from pre-revenue to Series A.
I've been building web products for 14 years, usually as the first or lead frontend hire. Was onsite in SF and Berlin earlier in my career, been remote from Europe for the past six years.
- Glean AI - built international payments and the features that got the company to first revenue
- Credit Karma - worked on marketplace search for financial products
- Movieo.me (co-founded it) - got to the front page of Product Hunt and HN; 500K visits in the first month with no marketing spend
I do my best work with founders and product leaders, owning the frontend and thinking about what actually moves the business. I'm self-managed, communicative, and easy to work with (happy to share references).
Most interested in early-stage SaaS and FinTech, but I'm open if the team and product are right. Part-time, fractional, or full-time with flexible contracts.

Senior Frontend Engineer — 10+ years building web products from scratch, often with small teams and directly with founders.
Remote-first (previously onsite in SF & Berlin). I focus on UX, delivery, and working independently. Open to full-time or part-time contracts. If you need someone to own the frontend and move fast, I can help.
Hi! I’m Sinisa, a web developer with 10+ years of experience helping startups and companies turn ideas into real products. I’ve worked remotely for the past six years; before that, I was onsite in SF and Berlin, building with fast-moving teams.
Most of my work has been in SaaS and FinTech, where I’ve led front-end teams, built products from scratch, and worked closely with founders to decide what to build and how to get it to market quickly. I specialize in front-end, UX, and product development, but I’ve got enough full-stack experience to keep projects moving end-to-end when needed.
Always happy to hop on a call and chat about how I can help!

Hey! I’m a web developer with 12+ years of experience helping companies turn ideas into real products. For the past five years, I’ve worked remotely; before that, I was onsite in SF and Berlin, contributing to fast-growing companies (one acquired for $7.1B).
I focus on front-end, UX, and product development, but I’m also comfortable working with back-end code when needed. I’ve led front-end teams and built several products from scratch—always aiming for a great user experience.
Ready to jump on a call and chat about how I can help out!
I'm a seasoned web development expert with over a decade of experience helping companies take their products from concept to market delivery.
Over the past four years, I have been exclusively working remotely. Before that, I worked onsite in San Francisco and Berlin, collaborating with highly successful companies (one recently acquired for $7.1b).
My strengths are in front-end, UX, product development, but I also know my way around a back-end codebase. I have led multiple front-end teams and have also independently developed many products from scratch.
