Web app development, AI and IT services
HOLODEC builds custom web applications and provides AI integration, IT operations and consulting for organisations in Poland, the EU and Australia. Four things we do well.
Web application development
The whole way: workflow, UX, UI, development, testing and a smooth launch. One team, start to finish.
AI integration
AI where it earns its place — automating repetitive work and connecting language models to the tools you already use.
IT operations & support
The everyday IT that keeps you running: business email and collaboration suites, website hosting, accounts and reliable day-to-day support.
IT consulting
We help you map the workflow, choose the right technology and avoid expensive mistakes before they happen.
Who we build for
We build software for organisations where the work matters — in Poland, the EU and Australia. These are the worlds we know best:
Non-profits & charities
Tools built around tight budgets and real impact.
Education & home-schooling
Platforms for schools, tutors and home-education networks.
Training & certification
Systems for managing courses, learners and results.
Security & compliance
Software where access and accountability count.
Businesses — CRM & ERP
Custom CRM and ERP platforms for companies that have outgrown spreadsheets.
Online payments & billing
Online payment flows, billing and financial settlement built into your platform.
And if your organisation isn't on this list, that's not a problem — good software is good software, whatever sector you're in.
Case studies
Real projects, real results. More on the way.
Home-education management platform
A growing home-schooling organisation needed one place to run everything: enrolment, students, teachers, class registers, exams and events — across multiple locations.
We built a custom web platform with role-based access for staff, teachers and families, plus integrated registers, exam handling and an events calendar. It replaced a tangle of spreadsheets with a single system the whole organisation now runs on — supporting hundreds of students across several locations.
Allotment garden management system
Running allotment gardens means juggling plots, members, fees and paperwork — usually by hand.
We built a web application that brings it together: plot records, member management and the day-to-day admin that keeps an association running — in one clear, easy-to-use place. We also implemented online payments, so members can settle their plot fees directly through the platform.
And several more — some live, some still in the workshop.
How we work — our process
Five stages, the same every time: Discover, Design, Build, Launch and Grow. You always know what's happening and what comes next.
Discover
We listen first. We map your goals, your users and your constraints before a single line of code is written.
Design
Wireframes, user flows and interface — designed for the people who'll actually use it, not for a portfolio.
Build
Clean, maintainable code with regular demos. You see progress as it happens, not three months later.
Launch
Tested, deployed and handed over with proper documentation — so nothing depends on one person's memory.
Grow
We stay on. Support, updates and new features from a team that already knows your system inside out.
HOLODEC is a Rzeszów-based software company working with clients in Poland, the EU and Australia. We started in 2022 to do things the way we always wished agencies would: honestly, carefully, and close to the client. The people behind it have been building software for over a decade.
You talk to the builders
No account managers in the middle. The people who design and write your software are the people you speak to.
Built to last
We care about clean architecture and good documentation — so your system is still easy to maintain in three years, not a liability.
Focused
We take on work we can do properly. You're a client, not a ticket number.
- Clean, modern architecture you can grow on
- Proper documentation, so your system never lives in one person's head
- An easy-to-maintain codebase
- Modern, proven tools chosen to fit the job
- Security and data care built in from the start
Frequently asked questions
Over a decade of building and shipping software, across a wide range of projects. HOLODEC is where we brought that experience together under one roof — so you get senior people on your project from day one.
It depends on scope — a focused tool and a full platform aren't the same job. After a short conversation we'll give you a realistic range, not a number plucked from the air. No surprises later.
Most projects run from a few weeks to a few months, depending on complexity. We give you a timeline up front and keep you posted as we go — no silent stretches.
Often, yes. We'll review what's there, tell you honestly what's worth keeping and what isn't, and carry it on from a solid footing.
That's exactly why we obsess over clean code and documentation. We stay on for the long term — maintaining and growing what we've built, so you're never left stranded.
We've worked with education, non-profit, training and security organisations. If we don't know your world yet, our first job is to learn it — before we propose anything.
No. A lot of our best work has been for exactly that kind of client. We'll be honest with you about what's realistic for your budget.
Yes. We work with clients in Poland, the EU and Australia, and we're set up for smooth remote collaboration across time zones and in both Polish and English.
