The Constraint Is Electrons, Not Chips
A former Bitcoin miner just signed a $19B, 20-year lease with Anthropic, and Brookfield 5x'd its fuel-cell financing framework to $25B. The pacing item for the AI buildout isn't silicon. It's power, and the capital to secure it.

Cost Per Token Is Where the Fight Moved
vLLM shipped 0.24.0, SGLang landed agent-written kernels, and NVIDIA claims DeepSeek V4 got 5x cheaper to serve on Blackwell in a month. A look at where the marginal cost-per-token wins are actually coming from.

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
Booking and client memory for service professionals. The calendar that remembers who people are.

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.

Healthcare interoperability
Providers that did not talk to each other, made into one ecosystem. I owned the backend core and the admin interface.

An engineer who writes things down.
I have built for banks, hospitals, insurers and sensor networks. Most of it I cannot show you. All of it taught me something, and the lessons are not under NDA.

The Wire.
One letter a week on AI infrastructure, shipping on a deadline, and the craft of building things that last. No noise, no sponsors you did not ask for.
