About
Good work. No hassle.
Hi, I'm Killian Grant
I've been building software for over 20 years, mostly embedded with agencies and product teams. I'm just as comfortable pairing with designers on a creative build as I am going solo on something technical.
What I do
- Ship production software end-to-end. Frontend, backend, infrastructure.
- Audit and clean up existing codebases, including ones generated or heavily assisted by AI.
- Build custom tools and integrations: booking systems, intake forms, portals, and online ordering.
- Advise on architecture and trade-offs before the first line of code gets written.
- Scope work honestly with fixed fees or weekly retainers. No surprises.
Who I work with
Small agencies that need a trusted build partner when the bench is full. Business owners who have outgrown their DIY site and want something real. Teams mid-project who need a reliable hand to get across the line.
Let's talk. I'm available.
