Releases taking weeks?

The .NET platform wasn't built to scale per country. An update for France meant waiting on Germany. Releases took weeks. JoyDev rebuilt it with containers and Kubernetes. Each country now scales and deploys independently.
Every change rebuilds everything?

Every code change triggered a full rebuild — all packages, all tests. Developers waited. The wait was accepted as normal. JoyDev saw the cost and rebuilt how the system tracked what changed — so only affected code got rebuilt and tested. Still running. Every developer ships faster.
Where is the money going?
A land-based cash operations company knew money was leaking. Not how much. Not where. Their own tracking systems missed it.
JoyDev found the leak, then built the fix. Traced the money from transaction to payout to bank account. Built the system that showed exactly where cash was disappearing. Built the business and technical processes that stopped it. Platform runs without JoyDev.
Automotive marketplace and CRM. Built from scratch. Andrei called 200 dealers himself. Most said no. He learned why. He rebuilt. 20 signed.
Then came everything engineers don't usually touch: marketing, contracts, support tickets, partnership negotiations, payment disputes, even litigation. A major dealer network offered €170K to acquire it.
JoyDev also builds its own software and funds it from personal savings. The ones that didn't ship cost real money. The ones that shipped cost even more.
The same person who finds the problem builds the fix. When you have to build it yourself, you don't miss the real problem.
The first conversation finds what the team missed. Once you see it, the fix is obvious. That's where most of the value is.
JoyDev works best in long-term relationships. The longer JoyDev stays, the sharper the work gets. Retainers, project-based work, or equity partnerships.
Every engagement starts with a conversation. No commitment. No pitch deck.
Every month it sits unsolved, it gets more expensive.
