Things I build for myself.
Small products shipped under my own name. Each one is a test rig for the shop and a source of notes.
Mk I · Mobile
Low Bar
A habit tracker that sets the bar low on purpose. Show up, mark the day, keep the streak honest.
Pre-launch
Mk I · Dev tools
Deslopping
Proof that an engineer read the AI-written code before approving the pull request. Comprehension, not vibes.
In progress
Mk I · SaaS
Bookleys

DevLazar.
One engineer, three stations.
Lazar Stanković PR DevLazar · Clients abroad
The company behind the work. Custom software, MVPs on a deadline, and backend systems that have to hold when the traffic arrives. Everything leaves the shop with drawings.
Station 01
Proof of concept, MVP, product
Built fast with AI to a working POC in days, then the MVP in weeks, then the full product. Each stage scoped to survive the launch.
Station 02
Backend architecture and scale
Pipelines, auth, APIs under high-frequency load. Monthly retainer.
Station 03
Launch Survival Audit
A fixed-price inspection before your system meets its users.
