Freelance software & systems developer
Software that adapts to your process, not the other way around
Your business has its own way of working, and I build custom software around it. I handle the complex work so you can stay focused on what matters most.

Approach
Software should adapt to your process, not the other way around
Your company already has a way of working that took years to get right. Good software supports that process flow instead of forcing you to rebuild it around a tool.
Off-the-shelf software
Your process bends to fit the tool
- Your team is retrained around the software's steps
- Workarounds and spreadsheets cover what it can't do
- You pay for features you never use
Software built for you
The tool follows the way you already work
- Mirrors your real process flow, step by step
- Changes when your business changes
- Only what you need, with nothing in the way
I handle the difficult part
The technical decisions, the integrations, the edge cases, the hardware: that is my job. You stay focused on what matters most, which is running your business.
Skills
From circuit board to cloud
Most systems are built by several specialists. I work across every layer, so one person understands how the whole thing fits together. Select a layer to see what it covers.
Web & mobile interfaces
Fast, responsive interfaces that work on any screen, built to be clear for the people who use them every day.
- Frontend / web UI
- ReactNext.jsTypeScriptTailwind CSSHTML & CSS
- Mobile
- AndroidiOSCross-platform apps
What I can build with this
- Customer-facing websites and web apps
- Admin dashboards and internal portals
- Mobile apps that talk to your systems or devices
Services
Tell me the problem. I'll build the solution.
I don't sell a fixed menu of packages. Every solution is shaped to your process flow, and I take care of the technical complexity. These are the kinds of things clients ask for.
Custom web applications
Web apps built around your process: portals, dashboards, booking and ordering systems.
Mobile apps
Apps for your customers or your team, connected to the same data as the rest of your business.
Business systems & databases
Inventory, billing, records and reporting systems that replace spreadsheets and manual work.
APIs & integrations
Connect the tools you already use, and automate the steps people currently do by hand.
Embedded & IoT devices
Firmware for devices that sense, control and report: from first prototype to working unit.
Electronics & PCB design
Custom circuit boards designed for your product, ready to send to a manufacturer.
One developer, the whole product
Need a device, its firmware, and the app that controls it? I can deliver all three, without handoffs between separate teams.
How I work
Corporate discipline, without the overhead
The habits that keep large projects on track work just as well on small ones: clear requirements, documentation, testing, and delivery you can rely on.
01
Discover
I learn your process flow as it is today: who does what, in what order, and where it slows down.
02
Plan
You get written requirements, a clear scope, and a timeline before any code is written.
03
Build
I build in stages and show working progress regularly, so there are no surprises.
04
Deliver
Tested, documented and handed over properly, with support after launch.
About
Experienced, and now independent
Over the years, I've built deep knowledge across fields that might seem unrelated: assembly language programming, microcontrollers, PCB design, 3D design, web development, and mobile app development among others. Together, they're exactly what it takes to build complete systems where hardware and software work as one. What sets me apart is that I understand both sides, and the protocols that connect them. Some might call me a jack of all trades. I call it seeing the whole system.
Now I'm bringing that experience directly to clients. As a freelancer, I work closely with the people who will actually use the system, move quickly, and build exactly what your business needs, not what a product roadmap dictates.
Because I work across both software and hardware, I can take your idea all the way to a working solution, whether it's a web app, a mobile app, a database-driven business system, or a custom device with its own electronics and firmware.
