I just released Stepped Actions, a Rails engine for orchestrating complex workflows as a tree of persisted actions that run through Active Job. It’s extracted out of Envirobly and battle tested in it’s current form for over a year.

Envirobly – Efficient application hosting platform
Envirobly.com is a startup I solo founded and launched in October 2025. It’s a culmination of an intense 3 year work, crafting a platform to deploy web applications to, while keeping the costs manageable.
It runs the full lifecycle of application infrastructure on AWS. It connects to a customer’s AWS account, lays down regional foundations (VPC, NAT, Traefik gateways, Route53 DNS, Managed Prometheus), and lets teams ship services, databases, and gateways with zero-downtime deploys, live logs and metrics.
locport – Manage localhost ports
There are many solutions to the problem of running multiple (web) applications on the same machine, during development. You can use various proxies (puma-dev, localcan, traefik, nginx…) and DNS to set up custom hostnames. Which is something I’ve been doing in the past. But there is a more direct and simpler approach.
tinyups3 – streaming S3 uploader
Working with the official AWS S3 CLI, as well as tools like s5cmd I quickly realized they aren’t optimized for resource constrained systems, rather more towards uploading as fast as possible and in parallel. This is great for most use cases, but not when you want to minimize the impact on the system, like during frequent backup operations and on a system with half a gig of memory for example.
testerobly – lightweight automatic test runner
I’ve been running into issues, like intermittent crashes, with guard, which is a favorite amongst Rubyists, when it comes to automatically running unit tests on a file change. I’ve decided it would be a fun exercise to create my own tool, addressing my needs specifically:
CRM system
Integrated business management web app for a sales company with CRM features. The functionality this Rails app provides is extensive:
Educational Software for Windows and MacOS
This desktop educational software for Microsoft Windows and Mac OS X is built using web technologies—powered by the awesome nw.js platform. I was responsible for the whole project from start to finish, from the initial brainstorming and design of the functionality with the client, to the choice of technologies, design of the user interface and programming implementation of the functionality.
Effort – Personal To-do and Project manager
I open sourced a Rails app that I’ve been personally using for years for simple project management. The code is available on Github under the MIT license. From the README:
Latest iteration of klevo.sk
To start 2015 in style, I’ve got a new theme for this website. Build from ground up to put the focus on my portfolio, clear typography and content. CSS were hand crafted, mobile first. On the backend - good old WordPress. Since all the cool internet kids are switching to https - I am following suit. For extra speed (and a free SSL certificate) I am utilizing CloudFlare to sit in front of the host.
Dockerized Percona MySQL Server with automated replication, tools & tests
I developed this container to solve specific needs and alleviate pain points present when dealing with deployment and administration of MySQL on servers that I manage.
