Selected work

Platforms businesses run on.

From regulated fintech to hospitality and education: systems we designed, built and took to production.

Vigilant AI

Fintech · Insurance · Regulated industries

Agentic AI platform for regulated financial services

Built from an empty repository: infrastructure, backend services and the agent runtime. Agents work inside the tools teams already use, with a real-time policy check on every action, audit-ready decision logs and human approval gates.

Smoobu

HomeToGo Group · Berlin

Multi-tenant website builder for vacation rentals

A website builder that lets property managers launch and run their own booking sites, a custom search engine written in Go, and an AWS architecture designed around the platform’s tenancy model.

Restaurant ordering platform

Built, run and acquired

Acquired

Every ordering channel, one order pipeline

QR, NFC, tablet, SMS, web, mobile app, digital menu and in-person orders on a single pipeline. Every venue got its own automatically provisioned infrastructure on Kubernetes, with real-time order events, payments and subscription billing.

Supercourse

Softweb · Listed on the Athens Stock Exchange

Education platform and native mobile apps

The supercourse.gr platform, its iOS and Android apps, and a fully custom school management system for lessons, students and scheduling, built without an off-the-shelf base.

Renfluence

Influencer marketing

Campaign platform with TikTok integration

Campaign management platform and TikTok integration built from scratch. It runs five- and six-figure campaigns for brands including Aegean Airlines, Uber and Apivita.

Grecotel

Hospitality · via GlobeOne Digital

Web platforms for a leading Greek hotel group

Web platform delivery across the estate of one of Greece’s largest hotel groups: property sites, booking journeys and content at scale.

Why Web33

A small studio with big‑platform experience.

  1. 01

    Senior engineers only

    The people you talk to are the people writing your code. No account managers in between, and no juniors learning on your budget.

  2. 02

    Architecture before code

    We design around your business model (tenancy, data, scale, compliance) before the first commit, so the system still fits in year three.

  3. 03

    You own everything

    Source code, infrastructure and accounts are yours from day one, documented well enough that any competent team could take over.

  4. 04

    We stay after launch

    Monitoring, maintenance and new features, with a support desk for live systems. Launch is where the work starts, not where it ends.
