Systems that can't go dark
A flight display doesn't get a maintenance window at peak hour. I design for reliability first and treat operations as part of the product.
I build the software airports run on.
I'm Daniel, a Principal Software Engineer in Cluj-Napoca. For 18 years I've shipped production software, and since 2019 I've built the systems AirportLabs delivers to airports worldwide. I also build LLM-powered products and multi-agent systems, and agents are part of how I ship.

How I work
Across the whole stack
From PHP monoliths to microservices, TypeScript front ends, GraphQL APIs and Go data services. I also own the path to production: CI/CD, automation and Linux.
Teams that ship
I've been a team lead since 2020 and still write code every week. Clear direction, honest reviews and sensible standards do more for delivery than any single commit.
Selected work
AirportLabs · Aviation SaaS
VisionAir
A unified passenger communication platform for airport operations: the flight information people look up at when they need to know where to go. I've worked on it since 2019.
AirportLabs · Data platform
ADR
Data integration and API platform for aviation. It connects to client data services and normalises what arrives into shared models.
AirportLabs · Passengers
Pocket Flights
Passenger travel assistant from the same AirportLabs product family as VisionAir.
Founder · Live product
pofta.app
Recipe and meal-planning app with URL import, shared shopping lists and AI suggestions, across web, iOS and Android, in four languages.
Side project
AI trading assistant
Self-hosted assistant with a multi-agent analysis pipeline, live market quotes and paper trading. No real money involved, plenty of engineering.

The company's product, built for gas and energy providers and serving retail facilities across Germany and Austria. I developed, maintained and automated its delivery for over six years.
Open source · Tooling
git-custom-hooks
Git add-on for custom pre and post hooks, written at eins+null to prevent human error and make deployments easier.

AI engineering
LLMs in production
pofta.app uses AI for recipe extraction, quality evaluation and ingredient identification. An orchestrator routes each call across Gemini, Claude and OpenAI-compatible models, with automatic fallback when one fails.
Multi-agent systems
In my trading assistant, scouts gather market data, specialists analyse it, a devil's advocate challenges each signal and a risk manager reviews it. A shared LLM router handles budgets and validates structured output.
Agentic engineering
Coding agents are part of my daily work, at AirportLabs and on my own products. I built the trading assistant with nine specialised Claude agents, from architect to security reviewer, and kept the product decisions for myself.
