● Available for new B2B contracts

I ship hard systems alone — infra to UI.

One senior engineer who takes a product the whole way: self-run cloud infrastructure, data and ML pipelines, AI products, browser automation that survives bot-detection, and the interface people actually use. No team to coordinate, no managed black boxes — just shipped systems.

What "end to end" means

One person, the whole stack.

Most contractors own one layer. I own the line from the metal to the screen — which is why the pieces actually fit together.

01 · Infra

Bare-metal k3s, GitOps, secrets, observability — production clusters I run myself.

02 · Data / ML

Lakehouse, training pipelines, model registry — data infrastructure without the enterprise tax.

03 · AI products

LLM agents that do real work and explain every action — not demos, shipped products.

04 · Automation

Browser automation that survives modern bot-detection — my own stealth engine.

05 · Product / UI

Operator dashboards and front-ends people actually use, wired straight to the backend.

Selected blueprints

Things I've built end to end.

Each was taken from empty repo to running in production by one person. These are the patterns I bring to your contract.

BLUEPRINT 01 AI product

Paceline — an autonomous Meta Ads copilot

Problem. Media buyers are expensive, opaque, and keep office hours. Built. An LLM agent loop that drives a real ad account through a clean port/adapter tool layer, explains every action in plain language, and never writes without a human click — plus invite-only access control, per-team subscriptions, a VPN-only Kafka-decoupled admin app, and a Kafka→ClickHouse→Superset product-intelligence stack. Outcome. A live SaaS, shipped and operated solo.

BLUEPRINT 02 Automation

Browser automation that doesn't get blocked

Problem. Modern sites fingerprint and block automation — canvas, audio, TLS/JA3, behavioral signals — so off-the-shelf Playwright and Puppeteer get caught. Built. My own anti-detection browser engine plus an isolation layer that spoofs fingerprints, mimics human behavior, and isolates concurrent sessions — driving real web apps reliably and undetected at scale where the standard tools fail. Outcome. Clean-room automation that passes detectors which flag everything else (0% on CreepJS, headless).

BLUEPRINT 03 Platform / infra

A self-run cloud platform on bare metal

Problem. Managed clouds are expensive black boxes; past a point you're paying rent and losing control. Built. A multi-node k3s cluster on raw VPS over a WireGuard mesh: GitOps with ArgoCD, Vault + External Secrets, full observability (Grafana / Loki / Tempo / Mimir / OTel), CNPG Postgres with S3 point-in-time backups, and automated TLS — running 25+ databases, ML pipelines, and every product on this page. Outcome. Production infrastructure operated solo, no managed crutches.

BLUEPRINT 04 Data / ML · quant

A lakehouse and ML pipeline, lean

Problem. Most teams over-build their data stack and pay enterprise prices for it. Built. An Iceberg / Hive / Trino lakehouse on object storage, Argo Workflows + MLflow for training and model registry (a self-hosted ZenML replacement), and backtesting systems that report the bottom line in dollars vs. buy-and-hold — not just Sharpe. Outcome. A full data platform at a fraction of the usual cost and complexity.

How I work

Senior, solo, accountable.

No layers between you and the person building the thing. Pick the engagement that fits.

Project

Fixed scope, shipped

A defined system, designed and delivered to production. You get the running thing, the infra it runs on, and the docs to keep it.

Fractional

Embedded, part-time

A senior/staff engineer in your team a few days a week — owning a hard surface end to end while your team moves on the rest.

Advisory

Architecture & unblock

Architecture reviews, a second pair of eyes on a thorny system, or getting a stuck build moving again.

Full ownership

I own the outcome, not a ticket. From the cluster it runs on to the button you click.

No black boxes

I prefer hackable internals over managed services I can't see into — and I run the infra to prove it.

EU-based, async

Based in Switzerland, working with EU and international clients. Clear written updates, no status theater.
