I build production software that businesses rely on every day.

Senior software engineer and architect, 15+ years designing, building and operating business-critical production systems. I design the architecture, build the implementation, deploy to production and keep systems running for years. Recently focused on production AI: OCR and LLM pipelines, computer vision and document automation that run reliably in real business workflows.

Based in Celje, Slovenia (CET). Open to remote roles and international projects.

What I do

Systems that stay in production

Not prototypes. Software that runs orders, stock and daily processes, and keeps running for years.

I understand legacy and real business

Not just code: how data moves between systems, where it breaks, and what that costs the business.

I own the whole thing

From architecture to production operations. One person accountable for the result, not just a feature.

Production AI, not demos

Selected work

Kontiqo

Co-founder / CTO, AI & Systems Architect

A production AI platform that recognizes and posts financial documents into accounting and ERP systems.

  • Designed and built the production architecture, OCR / LLM pipeline and validation framework
  • Multi-tenant, per-client AI models with validation pipelines
  • GDPR-compliant, EU-hosted, auditable approval workflows

Retail commerce at scale

Software architect, Tuš (one of Slovenia's largest retail groups)

A B2B commerce platform of 45,000+ SKUs with per-customer contract pricing.

  • Asynchronous ERP integration, automated order transfer
  • SSO / OAuth gateway and identity systems
  • Unified mobile API gateway (one API instead of five) and loyalty program

Computer vision in retail

Real-time detection systems (YOLOv5)

Turning camera feeds into operational signals on the shop floor.

  • Checkout-queue detection with automated alerts to open registers
  • Vehicle detection triggering zone signaling
  • Deployed on the shop floor, integrated with staff workflows

Independent practice

Software architect / founder, MNJ s.p.

30+ production systems across retail, wholesale, accounting and cinema.

  • Employee-scheduling optimization reducing staffing costs
  • Automated accounting analytics saving ~20 h/month
  • 9+ years longest continuous client relationship

How I work

01

Start where the money leaks

Not with code. With the process that costs time and mistakes.

02

Propose a solution, not a feature list

Concretely: what, how, and the trade-offs.

03

Ship to production

Not a demo. Production from day one, with accountability.

04

Operate and improve

Launch is not the end. I keep systems running on real data.

What I'm looking for

I'm interested in backend engineering, production AI and architecture roles where I can take real ownership of systems, work closely with product teams, and build software that stays in production for years.

I work across the whole stack: from databases and distributed systems to OCR pipelines, infrastructure and production operations. I prefer owning complete systems over isolated components. This end-to-end approach allowed me to architect and implement most of Kontiqo's core platform.

I like hard engineering problems where reliability matters more than hype.
