ProtoCode is a software engineering studio in Zrenjanin, Serbia, led by Miloš Živković. We take software from first prototype to hardened production, with cloud and security built in, and AI where it helps.

Tell us the problem. We’ll name the work.
Most projects start with a sentence like one of these. On the right is the service that answers it.
We need a platform built around how we work.
Custom software development
Web applications, APIs and back-ends, designed around your process and built to last.
Our cloud bill grows faster than our users.
Cloud integration and management
Architecture on AWS, Cloudflare and serverless, sized to the load you actually have, with FinOps to keep the bill in line.
A customer asked how we protect their data.
Cybersecurity
Security by design: secure architecture, DevSecOps and vulnerability management.
An enterprise client wants SOC 2 or ISO 27001 from us.
Compliance readiness
Policies, technical controls and evidence, so your platform is ready for a SOC 2 or ISO/IEC 27001 audit. Readiness work, not audit or certification.
Releases are slow and a little scary.
DevOps and continuous delivery
Automated pipelines, infrastructure as code and observability, so releases become routine.
Could AI take over this repetitive work?
AI integration and automation
LLMs, agents and retrieval built into the tools your team already uses.
We are not sure what to build first.
IT consulting and strategy
Architecture reviews and a plan you can act on, before money goes into code.
The sentences on the left are example situations, not client quotes.
All services in detail →From prototype to production.
Projects move through five revisions. Each one ends with something you can open, review and react to.
Discovery
The problem, the people and the constraints, before any stack is chosen.
Design
Architecture, plan and estimate you can review.
Build
Small, reviewed steps, with a staging link early.
Hardening
Security, load and backup checks before launch.
Maintenance
Monitoring, updates and a person who answers.
We build agents-first. Before an agent writes any code, we define the architecture, conventions and context it works in. Agent-written code has to pass tests and CI, and Miloš reviews every change before it ships. How we build
Sectors we build for.
Selected work.
We don’t name clients. Each project is described by what we did and the system we worked on.
Led by an engineer.
