About
Good work. No hassle.
Hi, I'm Killian Grant.
I have been a software engineer for over 20 years. Most of my career has been in
consultancies. I'm comfortable teaming up with designers and account managers on creative projects, joining pods
to build enterprise platforms, or going solo.
You know what you want to build but not how to get there. I'll help you figure out scope, timeline, and
cost
before a single line of code gets written.
Your AI-generated codebase needs an actual engineer.
AI tools can write a lot of code fast. That doesn't mean it's good. If your codebase was generated or
heavily assisted by AI, and now it's fragile, hard to maintain, or nobody on your team fully understands it,
I'll audit it, clean it up, and get it to a place where humans can work on it again.
You need ongoing engineering support.
Not every project needs a full engagement. Sometimes you just need a reliable person you can call when
technical work comes up. I'm available on retainer for teams that want consistent access without a full-time
hire. You'll get the same quality and attention whether it's a two-hour fix or a six-month build.
For Businesses
Sites that convert. Tools that work.
You have outgrown your current brand and digital presence.
Your business has changed but your brand hasn't. I'll help you start fresh with a new identity, website,
and digital assets that reflect where you are now. Not where you were five years ago.
Your website isn't bringing in customers.
If people can't find you or leave your site before picking up the phone, something's wrong. I'll build a
site
that loads fast, looks good on every device, and shows up when people search for what you do.
You need custom tools or integrations that actually work.
Booking systems, patient portals, intake forms, online ordering. Whether you need something built from
scratch or you need your existing tools connected so they stop fighting each other, I'll handle it. Scoped
and
priced up front so you know exactly what you're getting.
For Agencies
You sell the work. I build it.
Your team sold a project. Now you need someone to build it.
You closed the deal but your bench is full. I step in, pick up the scope, and deliver. Your client never
knows I'm not on staff. I scope accurately, communicate clearly, and ship what I said I would, when I said I
would.
Your project got more complex than expected.
The build started simple, then scope grew. The CMS needs custom work. The integrations are tricky. You need
someone who can handle the parts your team can't. I'll assess what's actually needed, give you an honest
estimate, and do the work right.
You are in-between vendors.
You hired someone, and it didn't work out, or you're mid-project with no one to finish it. I'll pick it up,
figure out where things stand, and get it across the line.
