Every road has its stops, and each one left a mark. The kite flies at the newest; follow the string down and you walk back to where it all began.
As Principal Engineer at re:cinq I work as a consultant with engineering organisations that want to become AI native, focused on software factories: the platform and operating model for running coding agents at scale. I don't build or sell a product. I help client teams set up their own factory, the practices around it and the engineers who run it. Our open source, Lore, Floor and the AI agent subsystem, shows what that looks like in practice. The stack is TypeScript, Go, Rust and Kubernetes, with D where it fits.
At Optilyz, I contribute to a Direct Mail automation platform, enabling the sending of millions of paper mails annually. Within the pricing team, I optimize pricing strategies for diverse mailing configurations across countries using TypeScript, AWS CDK, React, and MongoDB.
I develop an open source, event-driven, geo data platform, which is addressed to NGOs, conservation scientists and professionals and natural-resources managers. The platform is developed using node.js, Ember.js and DLang and it can be installed on a kubernetes cluster or using packages. Currently it is used by Green Map to map green places around the world.
While at RIDE, I contributed to reshaping investment practices in Germany, I applied software craftsmanship methods like TDD, Pairing, CI, CD, and trunk-based development. Our tech stack comprised Node, JavaScript, TypeScript, and GraphQL.
I was part of the data integration team, working with a micro-services infrastructure handling millions of http requests a second. I wrote low-latency apps with DLang by using Asynchronous I/O, caching, fibers and high performance databases that handle real time data.
I focused on generating new ideas and ways of approaching different problems with testing and developing software, hardware development and helping others. For robotic arms I worked with D and Java. For a real time note taking web app with browser plugin support, I worked with Node.js and Ember.js. For an in-house mobile device orchestration tool I worked with DLang and Java. I also set up and mantained a GitLab instance, CI servers on various operating systems, and deploy servers with docker and artifactory, as part of the dev-ops infrastructure.
I worked on some backend services with node.js and ember.js. After the iOS developer left the project I continued working on the apple tv and iOS apps
I wrote various C components for NI LabWindows™/CVI, a C IDE used by engineers around the world to create software that makes efficient and accurate measurements. Outside work hours, I started organizing recurring Refactoring Dojos and Code Kata sessions at the office.
Apon wants to build a web service for creating mobile applications. I have written various modules for this service, and because I have a diverse experience, I contributed with both web components, such as games, media players or online shops and also with a system that converts web applications in native applications.
I wrote a web GIS application which I occasionally maintain. The application helps OGM members to collect points of ecological interest. And because they do not work in an office, the application adapts easily to any device and it can be used even when there is no Internet access.
After I have built two applications to centralize working hours in various departments, it came the turn of a third: an application which helps the users follow on and estimate the projects' evolution based on available resources.
I joined the Incubator in Bucharest, where in addition to drawing on walls I also contributed with posters and the incubator107.ro website.
I wrote various static or dynamic websites with Wordpress or CMSushi.
I made Wordpress / Drupal / Joomla themes for cmsjunkie.com website.
At every stop something was built and left behind for others to use. The newest grows at the top, and the roots reach all the way back to high school.
An app that enables hobbyists and professionals alike to easily collect map data and collaborate on it.
A D programming language library that help developers who want to do test driven development.
An extensible test runner that wants to be compatible with any D programming language project.
Shared context infrastructure for Claude Code: organisation conventions, architecture decisions and agent memory served through an MCP server, plus background agents that onboard repositories, flag documentation gaps and review pull requests.
A workflow engine for pipelines of AI agents. An assembly line is a versioned graph of stations; an assembly run walks it and hands each visit to an agent in a pod, a service worker or a person. Floor stores the definitions and decides what happens next, and never does the work itself.
The cheapest, most boring way to run coding agents on Kubernetes: a run is an Agent resource, and a reconciling controller runs Claude Code, Codex or Gemini CLI against the repository and writes the result to its status. Batch runs at half price, a single signed install, no database and no UI to host. Written in D.
A counterfactual audit of bias in LLM résumé screening: one real baseline résumé, variants that change exactly one signal at a time, and a measurement of how each model's verdict moves. 25,500 evaluations, with placebo and reasoning-transplant controls.
The easy way to build JSON APIs with D and vibe.d.
A traveller who learns a trick is bound to tell it. These are the stories told at other people's fires: workshops, courses and talks.
This talk shows how the new Open Green Map app works, and advantages of using DLang and Ember for a GIS app.
https://media.ccc.de/v/bucharest-121-mapping-green-goes-open-with-the-gis-collectiveI created a full day workshop in which we have a quick look into the history of the web, the protocol, the http servers, load balancing, and how a web browser works. Each section contains an introduction with Q&A and a practical part where participants get to apply the presented concepts.
http://tabaradetestare.ro/tabara-de-toamna-2016I created a half day workshop focused on providing a good introduction to solving problems using functional programming. The challenge for participants is to figure out which range of numbers was generated using a random algorithm.
https://github.com/isitrandomTogether with a few colleagues from Altom, I created a Selenium course for the Cluj IT Cluster. The course contained 3 modules, each spanning over 3 days.
Module 1 - Introduction to OOP programming and TDD
Module 2 - Introduction into Selenium and Page Object Model
Module 3 - Advanced Selenium techniques and introduction to CI

The languages of the beasts tamed along the way, and the places where their secrets are kept.
Over time I spoke many languages, some mathematical (Maude, cafeObj), other logic (Prolog) and some forgotten (BASIC, Visual Basic, Pascal, Objective-C, Swift, C#). Right now I speak: D, TypeScript, JavaScript, HTML/CSS, Rust, Go, Java, C/C++, PHP
Like any other programming craftsman, I have to keep data somewhere. These days that is PostgreSQL with pgvector and Dgraph for the software factory, MongoDB for the geo platforms, and SQLite wherever one file is enough, but I can master any database that comes my way.
Along the way the traveller picked up some magic items, the kind that help tame beasts: a few diplomas, and a handful of charms learned from masters near and far.
