One offer, done properly: your product, built and shipped.
I take software from idea to production on a fixed scope and a fixed price. One senior engineer, accountable end to end.
Where I do most of my work
-
Software for congress stands
Touchscreens, photo experiences and engagement analytics for pharma and medical congresses, with worked examples of time and cost.
-
Software for connected hardware
The cloud platform, device link, safe updates and remote access for hardware installed in the field.
-
Web products and platforms. The case management system thousands of Citizens Advice advisers used every day, a recruitment SaaS designed, built and run end to end, and platform work for Babbel and Carwow. Fifteen years of Ruby on Rails, from the first commit to keeping it running in production. Builds this size usually start with a scoping sprint. See the case studies.
The problem with the usual options
Hiring an engineering team takes months you don't have. Agencies bill by the week and scope drifts. Solo freelancers are a lottery. What you actually want is a working product, a known price, and one accountable person who has shipped this kind of thing many times before.
What you get
A complete, production ready application: designed, built, deployed, documented, and supported. I work AI accelerated: modern agentic tooling does the heavy lifting, but every decision is senior led, backed by fifteen years of building products by hand for companies from startups to Johnson & Johnson, GSK, Babbel, and Carwow, and for regulated environments including the NHS.
How it works
-
Step 1
A short call
Thirty minutes, free. Smaller builds, like most congress work, get a fixed price straight after it.
-
Step 2
Scoping sprint
For bigger builds, after the call: one paid week that turns your idea into a written spec, an architecture and a fixed price. How the scoping sprint works.
-
Step 3
Build, launch and support
Working software you can see at every milestone, at a fixed price. Then deployed, documented and supported, so it keeps working when real users arrive.
What this looks like in practice
Fixed window builds are what my case studies are made of: an edge to cloud analytics platform delivered in a four week cycle, an interactive event experience shipped in a four week sprint, and a complete SaaS product designed, built, and operated end to end. If your project looks anything like these, the process above is how they happened.
Not a build?
I also take contract engagements (a senior engineer inside your team, on a day rate) and fractional support (ongoing part time engineering without a full time hire).
When we hand Wagner a build with a hard deadline - a congress opening, a live event - it ships. Complete, working, on the floor when the doors open.
Ready when you are
Tell me what you're building. A 30-minute call is enough to know what the right next step is.
