Demos are easy now. The hard part is building a product you can confidently put in front of customers, inside critical workflows, and at the center of a growing business.
I test your idea with users and show you what to build.
I build a working version you can try, often within a day.
I engineer the whole product, front to back, to carry a growing company for years.
I design interfaces that make complex products feel obvious.
I build agents that run parts of your business, with a log of every step and an off switch.
I build AI into your product to do whole tasks for your users while they stay in control.
I get it live and keep it fast and affordable to run as usage grows.
After launch, I watch how people use it and keep making it better.
TRUSTED BY GLOBAL ENTERPRISES & PRODUCT-LED TEAMS
CodeFavorite is run by me, Nikola Vejin, a hands-on product and engineering lead.
I work on the kind of product problems where the difficult part isn't simply building it. It's understanding what should be built, reducing the complexity, making good product and technical decisions, and carrying the whole thing through to launch.
I usually work with growing companies facing a problem somewhere between product, technology, and operations. I work forward-deployed, directly with leadership and the people closest to the problem. It might be a product that needs to scale, AI agents connected to business data, or a manual workflow that needs to become simpler and more reliable.
I've been doing this for over twenty years now. I've built products for global enterprises like Kaman Corporation ($1.8B aerospace and defense), public figures like Ronda Rousey (first women's UFC champion), and product-led teams like AnchorFree (Hotspot Shield, 650 million downloads) and Twingate ($400M security startup).
If you're dealing with a difficult product problem, drop me a message.



We couldn't have made RoomHub without you.
Shaun RobinsonSVP, Product & Customer Experience, PleneoMost companies come to me in one of three situations. Pick the one closest to yours.
You have an idea for a new product or an AI feature, and you want to know it's worth it before the big spend. I test the risky parts with real users first. If it holds up, I build it properly and get it live.
You know AI could take real work off your team, but it has to plug into the systems and data you already have. That's usually where it gets hard. I connect it to your business data and roll it out carefully, so nothing your team relies on breaks.
Your product or internal tools are live, and your team and customers use them every day. Now they need to handle more, or they've gotten too complicated. I work with your team as the product and engineering lead and keep making them better.
A clear scope gets a fixed price, and open-ended work runs as an ongoing engagement.
Tell me what you're building. I'll tell you what I think.
I take on projects I believe in, and I build them to hold up for the long run.
If you're building something that has to work, I'd love to hear about it.
Tell me what you're building and where you're stuck. A few lines is plenty.
I come back with my take and any questions, and we see if it's a fit, no pressure either way.
I lay out how I'd approach it, what to build first, and what it costs.
