Featured AI Agents
Explore my showcase of intelligent agents designed to revolutionize workflows
Costia AI
AI-powered personal and shared expense manager. Scans receipts and invoices to create expenses in seconds, splits group bills Tricount-style, and delivers advanced statistics on where your money actually goes. It is offline-first — everything is stored on device and synced to the cloud when you are online — and it also acts as an identity provider, exposing a public API so other apps can push invoices straight into a user's account.
Ambrosia Recommender
Personalized supermarket assistant that revolutionizes the shopping experience. Learns your food preferences, manages dietary restrictions and allergies, suggests recipes based on your favorite ingredients, and helps you discover new products that align with your tastes. The system continuously adapts to your shopping habits, optimizing shopping lists and avoiding waste. You can now sign in with your Costia account, so every purchase lands straight in your expenses — no receipts to copy by hand.
The Unreal Times
A digital newspaper written entirely by AI — "the most reliable fake news". From a single prompt it produces the whole story: headline, standfirst, body and category, holding a journalistic tone and adapting to whichever language you pick. Every edition ships numbered by volume with its own top story, and pieces are filed across nine sections, from politics and economy to science, sports and culture.
Ambrosia × Costia
My products don't live in isolation — they talk to each other over open standards. Sign in to the supermarket with your Costia account and every purchase shows up in your expenses on its own.
Reading and writing are independent permissions, not a ladder: a shop writes and never reads. Only invoices:write requires verifying your brand's domain.
https://id.costia.app/.well-known/openid-configuration
Sign in with Costia
Costia is a full OpenID Connect provider on top of an OAuth 2.1 server: authorization code only, PKCE with S256 mandatory for every client, and neither implicit nor password among the grant types. Client authentication uses HTTP Basic, and the id_token returns a stable subject identifier plus the user's name and verified email.
Public invoices API
With invoices:write, Ambrosia pushes every purchase — line items, amounts and VAT rates — straight into the user's Costia expenses, no OCR and no receipt photos. With invoices:read another app can read them back, a tax adviser at filing season for instance. Writing requires proving you control your brand's domain.
Developer documentation
Client registration, the login flow, invoice submission, and a reference for scopes and error codes. Any merchant can integrate by following the same steps, once their domain is verified.
What I do
Two lines of work on the same engineering: platform architecture, and the AI products I design and operate.
Kubernetes in production
Migrating live customers off Docker Swarm onto Kubernetes with minimal downtime, across Google Cloud, Azure and on-premise clusters, with high availability and resilience designed in from the start.
One platform, many customers
The same architecture for everyone, adapting only what a given customer genuinely needs: cluster parameterisation, configuration and secret management under one shared standard.
Automated delivery
Images, Helm charts and Helmfile, database migrations, ingress, storage and version upgrades, all inside CI/CD pipelines with the manual steps cut down to as close to zero as it gets.
Agents in production
Agents in users' hands, with everything that forces: evaluating them, correcting them, and holding them up when the model shifts underneath. From code reviewers to assistants that learn from each person.
AI product, end to end
From the model to the app someone opens daily: backend, mobile, payments, offline sync, and all the unglamorous work between an idea and something people use.
Built on open standards
OpenID Connect, OAuth 2.1 and public APIs so my products talk to each other — and to other people's — instead of bespoke integrations that only work once.
Let's talk
If you're moving a platform onto Kubernetes, or you want an AI agent to get past the demo and into production — or both at once — drop me a line.
