Hi, I'm Gurwinder
I'm a freelance full-stack developer with 9+ years building SaaS products and business software. When you hire F Koin Tech, you work with me directly, from the first call to long-term support.
Nearly a decade of shipping software
I started as an Android developer and moved into full-stack web development. In 2020 I began working independently under the F Koin Tech name, and since then I've delivered 90+ projects for clients worldwide: SaaS platforms, CRM and ERP systems, web applications and integrations.
You work with me directly. I scope the project, write the code, deploy it and support it. I use AI tools to research, test and document faster; every decision and every line that ships is reviewed by me.

What you get from hiring one senior developer
The commitments behind every project, and the ones clients can hold me to after launch.
One accountable developer
The person who scopes your project builds it and supports it. No account managers, no handoffs, no re-explaining your business.
Business understanding first
I learn how your operation works before I design anything for it.
Built to be maintained
Reviewed, tested and documented code that you own, so any competent developer can pick it up.
AI-assisted, human-reviewed
AI tools speed up research, testing and documentation. I review everything that ships.
Support after launch
I keep maintaining and improving what I build, long after the first release.
Have a project in mind? Let's talk it through
Tell me what you're building or what isn't working. You'll get an honest view of the right approach, a written scope, and a straight answer if custom software isn't what you need.
- Step 1: Tell me what you're building, on WhatsApp or with the contact form.
- Step 2: A short call with me to understand the requirements. No sales pitch.
- Step 3: A written scope and estimate you can act on, with no obligation.
