Curriculum vitae

Senior Staff Software Engineer, Sleuth (San Francisco, remote)

The first engineer they hired, and the de-facto architect ever since. A prototype grew into a multi-tenant SaaS observability platform for DORA metrics, environment health and real-time anomalies, and the company to about 40 people.

• Architecture from zero: the multi-tenant data model, tenant isolation, service boundaries, API contracts, and the integration framework behind 30+ third-party services.
• Resilience: a circuit breaker system guarding over a million API calls a day, PostgreSQL advisory locks and Redis distributed locks for cluster-wide concurrency, and transaction-aware Celery tasks across 7 queues.
• The MTTR engine: attributes deploys to incident episodes with a two-pointer matching algorithm, which is where the platform's mean-time-to-recovery number comes from.
• Applied ML: a self-tuning anomaly detector for customer metrics, a fresh data point every 2 minutes, running for hundreds of clients for years without hand-tuning. How it works, explained with pictures.
• LLM work: the pipeline behind Sleuth's AI-usage analytics, and the small RAG behind the product's AI assistant.

Python Django Celery PostgreSQL Redis Elasticsearch Pandas

Software Engineer, Reciprocity (now ZenGRC, San Francisco, remote)

• Reverse-engineered the legacy query patterns, mapped the hidden dependencies, and rebuilt the model layer on top of what I found.
• Ran internal training sessions on development environments, performance work and code practices.

Python Flask SQLAlchemy PostgreSQL

Software Engineer, Innovatif (Ljubljana)

• Led the build of a full e-commerce platform.
• Built custom web applications for clients, and ran the deployment lifecycle on the Linux servers they lived on.

PHP MySQL JavaScript jQuery

Software Engineer, Infonova (Ljubljana)

First full-time job: an automated monthly invoicing system, from the calculation logic to the rendered documents.

C# JavaScript

Lecturer (student job), Housing Co. (Ljubljana)

Taught adults the basics of computers and Microsoft Office. The explaining-things career started before the engineering one.

Agents that do real work for me

Confetti, my own conference tracker: two Claude agents research conferences and return structured JSON, deterministic Python validates it and writes the data. Each agent gets two tools and a four-sentence brief and nothing else: no project context, no MCP servers, none of the coding-agent scaffolding. Every run carries a hard dollar ceiling and logs what it cost.

Writing this blog

I aim to make complex ideas clear and relevant, blending technical insight with a focus on the people around the code.

One product, all of it

My partner's business site, where I am the entire team: the full-stack engineer, the designer, the sysadmin, and even the marketing.

Teaching, and later conference speaking

I started teaching before I learned programming, and I never stopped. I've given several talks all over Europe, all in my own time, no sponsors and no employer agenda. The subjects that interest me most are the lies we tell ourselves: how we estimate, how we argue, how we misuse statistics, ... The full record and the talk catalogue.

B.Sc. Computer Science, University of Ljubljana

With a semester in 2008 at the University of Southern Denmark, in Odense, on exchange.
