Code2b builds the systems your back office runs on.
Fixed-fee automations, products and data work, built inside the tools you already use, from Athens, for businesses anywhere. Run by two brothers, Aleksandar and Dusan Janca. Alex leads engineering, Dusan runs operations and the client side. Both are on every first call, an in-house team builds every system, and you own what we build.

The build log · 2021 to now
Five years, kept as a running log.
The history of the studio, written the way we keep everything else: dated entries, one artifact each, and only the numbers that survived contact with production.

LOG-01
Full-stack from day one
Before the studio had a name, the work was already end to end: web apps, products, dashboards, and the data systems behind them, designed, built, and shipped whole. That range is still the foundation of everything below.

Large-scale data engineering
The work deepens into serious data: we design and run a hotel-rate collection engine for a client platform, reading rates around the clock in markets we had never set foot in.

LOG-03
Code2b gets its name. The automation years begin.
The brothers make it official: a studio in Athens. The focus shifts to automation: workflows wired across the tools businesses already run, shipped on a fixed scope and a fixed fee.

The pattern hardens into products
Invoices, bookings, back offices. The system count climbs and the patterns harden into products.

The AI reception year
The AI reception fleet answers for dentists, barbershops, and nail salons across Greece, every call logged, a human looped in on the judgment calls.

yourtrained.ai
The private AI work gets its own name: models that run on the customer's own hardware or a single-tenant EU server. Code2b keeps the automations and the data.

Time handed back, by industry.
Most of our clients are under NDA, so the names stay out. The numbers do not: each line is measured on a system running in production.
See how a build actually runs- 01Accounting~30 min/day · invoice reconciliation
- 02Consulting~15 hrs · per grant or compliance application
- 03Legal2+ hrs/case · research with niche-trained models
- 04Hospitality~10 min/booking · hotel systems kept in sync
Four of the workflows we run, with the time each gives back. Measured on live systems, not projected.
Two names, both on every first call.
Run by two brothers, Aleksandar and Dusan Janca. Alex leads engineering and architects every system. Dusan runs operations, the client side and delivery. Write to either of us directly.
