Where work gets stuck
Is your business outgrowing its current software?
Many businesses reach a point where spreadsheets, paperwork and generic software start creating more work instead of reducing it.
Too many spreadsheets
Critical processes are spread across Excel files, email attachments and manual reports.
Duplicate data entry
Your team types the same information into more than one system, and still cannot trust the numbers.
Paper-based processes
Forms, worksheets, signatures and reports still depend on paper, WhatsApp photos or a filing cabinet.
Disconnected systems
CRM, ERP, accounting and operational tools do not talk to each other, so people become the integration.
Software that doesn't fit
Off-the-shelf software forces your business to adapt to the product, instead of the other way around.
Manual administration
People spend hours on repetitive admin that could be a workflow, a mobile form, or a simple integration.
When off-the-shelf software no longer fits your business, custom software starts making sense.
What I build
Software built around your business
Custom business software
Software designed around your processes: operations platforms, management systems, internal applications, instead of forcing the business into a generic product.
Workflow automation
Replace repetitive manual work with digital workflows: approvals, reporting, task management, documents and notifications.
Mobile applications
Tools for employees, field teams and customers: field service, workforce management, inspections, data collection and customer apps.
AI automation
When it actually helps: document processing, data extraction, intelligent search, workflow assistance and communication automation, connected to your business data.
System integration
Connect the systems you already use: CRM, ERP, accounting, APIs and legacy software, so data moves once.
Customer & employee portals
Give customers, staff or partners secure access to the information and processes they need, without another inbox.
Proof of capability
Live software, not a portfolio of mockups.
I have already built serious production software across multiple industries. These are live systems, used every day, not a gallery of concept screens.

Two ways to work with me
First we find the simplest sensible solution.
Proven software
Start with an existing platform that already solves the problem, if it fits. Faster implementation, proven functionality, lower initial development risk, and configurable to the business.
- Faster implementation
- Proven functionality under real use
- Lower initial development risk
- Configurable to your business
Custom software
If not, I'll build a system around the company's specific workflow, including integrations, unique requirements, and ownership or control depending on the project agreement.
- Exact process fit
- Integrations with the systems you already use
- Unique requirements, without forcing a generic product
- Ownership and control, depending on the agreement
Track record

How the work is done
Work directly with the person building your software
You work with the person who designs and builds the system. No account manager standing between you and the person who actually understands your software. Direct access to senior expertise, from the first conversation through launch.
Direct communication
Talk directly to the person responsible for the solution.
Business and technology
Software is designed around business outcomes, not just a technical brief.
15+ years experience
Senior-level technical experience from the beginning of the project.
From idea to production
Architecture, development, integration and deployment can be handled as one process.
Process
From business problem to working software
Getting in touch does not mean committing to a large software project. If an existing solution can solve the problem, I'll tell you.
-
01
Understand
We start with the business problem and the way the process works today.
-
02
Simplify
Before building anything, we determine whether an existing platform, integration, automation or custom development is the simplest solution.
-
03
Design
Define the workflow, architecture and practical scope.
-
04
Build
Develop iteratively, with regular feedback.
-
05
Launch & improve
Deploy, integrate and improve based on real usage.
Who this is for
A good fit if...
- Your business has a process that spreadsheets or generic software no longer handle well.
- Your team is doing repetitive administrative work.
- Your systems need to exchange data.
- You need a mobile or web system around a real operational process.
- You want to work directly with a senior technical person.
Probably not a fit if...
You're only looking for the cheapest developer by the hour.
For technical decision makers
Architecture, platforms and delivery
The first half of this page is for the operational problem. This part is for the people who need to know how the software is actually built and run.
Native mobile
iOS and Android applications in Swift, Objective-C, Kotlin and Java, including field apps used every day, not demo builds.
Backend and platforms
PHP and C# systems, APIs, cloud hosting, and the operational backends behind the SaaS platforms above.
Integrations
Connecting CRM, ERP, accounting, legacy systems and third-party APIs so data is entered once.
Quality-managed delivery
Development, operations and secure data handling under an ISO 9001:2015 quality management system.
The person you'll work with
Hi, I'm Attila. Yes, I'm the one who'll build this.
I've been building software for more than 15 years, working on products and projects across Europe and international markets.
No account manager standing between you and the person who actually understands your system. Direct access to senior expertise.
Working with businesses in Ireland, the UK and across Europe.
Irish market focus
Working with businesses in Ireland, the UK and across Europe.
Irish market, European delivery
Software development for businesses in Ireland and across Europe. kasler.ie is the Irish-market site.
ISO 9001, not just good intentions
A certified quality process governs delivery, including the clinic records system used by a 3-country dental group.
Direct communication
You communicate directly with me throughout the project, not through a ticket queue.

Quality & governance
Delivery managed the same way for a clinic group as for a start-up.
My development, operations, and secure data-hosting process runs under an MSZ EN ISO 9001:2015 quality management system, effective 15 September 2026. It covers custom software development, ongoing operation, and secure data storage and handling, the same standard whether the project is a museum app or a clinical records system.

I write about what I'm building, as I build it.

Read the blogHave a business process that should work better?
You don't need a technical specification. Just tell me how the process works today and what you'd like to improve. Spreadsheets, paperwork, WhatsApp, or software that no longer fits is a perfectly good starting point.
