A senior team building secure-by-default software.
BulgariTech is a Sofia-based engineering studio focused on AI, cybersecurity, and platform engineering. We combine red-team experience, MLOps depth, and platform engineering rigor to deliver systems that hold up in production — and we share what we know through hands-on trainings.

What we optimise for
Three principles that shape every engagement, every hire, and every line of code we ship.
Security as a product feature
Threat models, secure SDLC, and supply-chain hardening are wired into every engagement — not bolted on at the end.
AI that ships
We go beyond demos: RAG systems, custom evaluations, and observability for LLMs that actually reach production.
Engineering integrity
Clear contracts, plain language, fixed-fee proposals where they make sense, and honest trade-off reviews — always.
People you’ll actually work with.
Senior engineers, not staff augmentation. Every BulgariTech engagement is led by experienced operators who write the code, run the workshops, and own the outcome.

People on the team
Elena Marinova
Head of AI Engineering
Builds production LLM systems end-to-end — retrieval, evaluation, guardrails, and observability for regulated workloads.
Stoyan Dimitrov
Head of Security
Former red-team lead. Threat modeling, penetration testing, and secure-SDLC programs across fintech and healthcare.
Iva Petrova
Principal Cloud Engineer
Kubernetes platform engineer focused on golden paths, FinOps, and progressive delivery for multi-cluster production estates.
Martin Georgiev
Senior Backend Engineer
Distributed systems specialist — event-driven pipelines, typed APIs, and data platforms that scale predictably.
Ana Todorova
Training Lead
Designs hands-on curricula for engineering teams. Two decades of workshop delivery across the EU.
Nikolay Stoev
Senior AI Engineer
RAG, fine-tuning, and inference infrastructure. Ships LLM products with rigorous evaluation harnesses.
Mira Ivanova
Staff Frontend Engineer
Design-system specialist. Accessible React, Core Web Vitals obsessive, and tooling author.
Boris Nikolov
DevSecOps Engineer
Bridges security and platform engineering — supply-chain hardening, policy-as-code, and zero-trust deployments.
Yana Koleva
Engineering Manager
Coaches senior engineers, runs the discovery sprints, and keeps every engagement aligned with business outcomes.
Dimitar Hristov
Senior Penetration Tester
Offensive security specialist — web, cloud, and network red-team engagements with detailed remediation guidance.
Radoslava Angelova
MLOps Engineer
Productionises ML pipelines end-to-end — feature stores, model registries, eval harnesses, and continuous training.
Petar Iliev
Site Reliability Engineer
Owns SLOs, error budgets, and incident response. Loves observability stacks that surface real signal.
Tsvetelina Vasileva
Staff Data Engineer
Streaming pipelines, lakehouse architectures, and analytics platforms built for compliance from day one.
Lyubomir Pavlov
Senior Platform Engineer
Internal developer platforms — golden paths, paved roads, and developer experience that actually saves time.
Gergana Stancheva
Product Designer
Ships interfaces that respect users and codebases. Strong opinions on accessibility, motion, and design tokens.
Andrey Kostov
Senior Security Engineer
Application security, cryptography reviews, and secure code review programs at scale.
Veronika Atanasova
Compliance & GRC Lead
Translates SOC 2, ISO 27001, and GDPR into engineering practice — no theatre, just controls that fit the SDLC.
Hristo Mihaylov
Senior Full-stack Engineer
Comfortable from database schemas to React component trees. Typed contracts everywhere, edge runtimes optional.
Kalina Nedeva
Delivery & Engagement Lead
Keeps engagements on rails — scoping, communication, and the unglamorous work that makes great projects happen.

Senior engineers, embedded with your team.
No staff augmentation churn. No junior pyramids. Every BulgariTech engagement is led by experienced engineers who write the code, run the workshops, and own the outcome end-to-end.
Research-grade AI
From retrieval pipelines to evaluation harnesses, we apply rigorous engineering to LLM workloads.
Team enablement
We pair delivery with hands-on training so your engineers own what we built together.
Regulated industries
Banking, healthcare, telco, public sector — comfortable working alongside compliance and audit teams.

Quiet, expert work — heard from the people who hired us.
CTOs, security leaders, and platform directors from fintech, healthcare, energy, and SaaS — all with one thing in common.
“BulgariTech rebuilt our risk pipeline end-to-end. The team's depth on cryptography and distributed systems is genuinely rare — and they shipped six weeks ahead of plan.”
Elena Marinova
CTO · Northwind Financial
“We brought BulgariTech in for a red-team engagement and ended up keeping them on as our secure-SDLC partner. Every recommendation came with working code and clear metrics.”
Marcus Reinhardt
Head of Security · Halberd Cloud
“Their AI engineers understand the production side of LLMs — evaluation, guardrails, observability. We went from a brittle prototype to a real product in one quarter.”
Sara Lindqvist
VP of Engineering · Vektor Health
“The Kubernetes training program reshaped how our platform team operates. Hands-on, opinionated, and tuned to our exact stack — the best workshop we've ever run.”
Tomáš Horák
Director of Platform · Lumen Industrial
“BulgariTech's threat modeling sessions surfaced risks our internal team had missed for two years. The remediation roadmap they produced was clear enough to present directly to the board.”
Isabelle Fontaine
CISO · Arclux Energy
“Rarely do you find engineers who can speak to regulators in the morning and then tune a Kubernetes autoscaler in the afternoon. BulgariTech's team does both without blinking.”
Daniel Osei
Engineering Director · PrimeCare Systems
“They took our RAG prototype from 61% retrieval accuracy to 94% in eight weeks, then instrumented the whole thing with traces and dashboards before handoff. Outstanding.”
Yuki Tanaka
Head of AI Product · Synaptic Labs
“We engaged BulgariTech for a GDPR technical readiness review. Their engineers actually understand the regulation — not just the checkbox version. Invaluable for our Series B.”
Klara Johansson
Head of Engineering · Forma Commerce
