My name is Sinisa. After my degree in IT, I began developing web applications for local businesses. In 2012, I started a Boutique Web Development shop with my two friends and I was happy to work long into the night learning more about what I loved. My years of dedication and experience coupled with my passion for technology and business allow me to truly enjoy the work that I do.


Various experience throughout Berlin startups has brought me to one of the highly successfull companies in San Francisco where I strived as a software engineer.

My personal preference for remote work has prevailed and had brough me back home mid 2019 where I quickly launched a small Web Consultancy business - Code Well Studio - and now looking forward to provide my extensive experience to you!

You can learn more about me and my work through my Online CV, Github portfolio, Medium articles or just check out my Case Studies directly.

CK Case Study


My friends and I love movies, but finding great ones to watch is usually a hassle. We had been searching for a simple and well-designed movie-browsing interface, yet we couldn't find one. Therefore, we decided to create one ourselves.

“I worked with Siniša in the beginning of my career and have followed his growth as a professional ever since. He’s a great, reliable developer who isn’t afraid to step out of his role when necessary. He pushed himself relentlessly to improve his skills on a daily basis.

After a couple of successful projects he moved to Berlin and then finally to Bay Area.

Siniša is down to earth hardworking professional and the person because of whom I started coding in the first place.

Can’t recommend him enough!”


“Sinisa possesses extensive and varied specialist knowledge, which he always deployed confidently and skillfully in practice. He demonstrated high personal initiative and identified fully with our company, impressing us in the process as well with his great enthusiasm.

Even in situations where his workload was extreme, he demonstrated the greatest resilience and found exceptional solutions for any problems that arose.”
