CTO-led, senior by design.
Meet the leadership behind BulgariTech — then see how our practice-led departments turn that technical direction into delivery.
The person behind the BULGARITECH
Kristiyan Velkov
Docker Captain | Chief Technology Officer | Speaker | Author | Meta Certified React Developer
I am the author of the official Docker documentation guides for React.js, Angular, Vue.js, Node.js, and Next.js — helping thousands of developers containerise modern applications the right way.
With 11+ years of experience in front-end engineering, DevOps, and technical leadership, I have conducted 350+ technical interviews, published four technical books, and spoken at conferences from London to Sofia. At BulgariTech I set technical direction across AI, security, cloud, and training.

How we’re organised
Five practice areas reporting to the CTO. Each is led by a senior engineer who still ships code, runs workshops, and owns outcomes end-to-end.
Reports to CTO
AI Engineering
Elena Marinova
Production LLM systems — retrieval, evaluation, guardrails, and observability for regulated workloads.
Reports to CTO
Security
Stoyan Dimitrov
Threat modeling, penetration testing, and secure-SDLC programs across fintech and healthcare.
Reports to CTO
Cloud & Platform
Iva Petrova
Kubernetes golden paths, FinOps, and progressive delivery for multi-cluster production estates.
Reports to CTO
Training
Ana Todorova
Hands-on curricula and workshops for engineering teams — tuned to the systems they actually run.
Reports to CTO
Delivery
Yana Koleva
Discovery sprints, engagement alignment, and outcome ownership across every client project.
Principles behind the structure
A deliberately small leadership layer and senior IC-led departments — so clients always work with operators, not account managers.
CTO-led architecture
Every major technical decision is reviewed at the leadership layer before it reaches production.
Flat, senior teams
Department leads are practicing engineers — no management layers between you and the people shipping code.
Security & AI together
AI and cybersecurity are first-class practices, not siloed consultancies bolted onto delivery.
Have a project, an audit, or a team that needs training?
