You don’t always get to build visual IDEs or deploy code with cat assistants.
Sometimes, you fix ancient servers. Rewrite haunted legacy systems. Or sit between a government and a database that hates you.
This is that list. Projects that paid well, tested patience, and still left something to be proud of.
What this page is
This is not one product.
It is a condensed record of serious paid work across enterprise systems, fintech, blockchain, digital signing, infrastructure, and teams operating under real constraints.
🧾 Chamber of Commerce
One of three devs maintaining and extending a labyrinth of 40+ servers.
Old code, moving parts, and real-world consequences.
We kept it alive. Somehow.
📊 Credit scoring on the chain
A blockchain-based credit scoring platform — users could self-generate a credit profile and prove it cryptographically.
Designed for transparency, built for Web3 skeptics.
🔗 Digital Signatures, but Modern
Helped rewrite a 17-year-old Yii system into modern React + Spring Boot.
Also developed a secure comms layer via WireGuard VPN to …securely integrate tiny edge machines (Intel NUCs) into the central signing system.
🎮 Ads, but in Games
We built a system to create, manage, and deliver in-game ads into Unity, Unreal, and web platforms via SDKs. The “digital signature” part? Mostly contracts and invoices — but still, it scaled.
We also added a crypto reward system: users could earn a token for watching ads, which they could later redeem — Web3 loyalty, minus the buzzwords.
🧠 ERP, but Make It Make Sense
Forget clunky CRMs. This ERP aimed higher: a unified beast combining ERP, blockchain, and data smarts into one sleek platform. I helped wire the brains: architecture, integrations, and the occasional firefight when “smart automation” turned rogue. Not every tool gets to be sexy — but this one got the job done, fast and loud.
💸 Crypto Fiat Gateway Platform
Built a system for companies and individuals in Bosnia to buy/sell crypto using fiat — complete with KYC flows, reporting, and AML compliance triggers.
🎮 Gaming Industry Survivor
Roles I played (literally): dev, PM, animator, 3D modeler, multiplayer server guy, and bot developer.
Mobile, PC, online, offline — if it had pixels, I poked at it.
🏁 Moral of the story
Some of the best skills come from jobs you’d never put on a sticker.
But they build your legend, paycheck by paycheck.
