About
Hi, I'm Wagner.
I have 25 years of software engineering and leadership, and I'm now applying that to AI architecture and agentic systems.
I've led engineering inside regulated financial services and insurtech environments, including ISO 27001 delivery, scaling teams, and building RAG-based tools and AI agents that ran real business workflows. I graduated from LSBU with First Class Honours and the Best Project of the Year award in 2010.
Through Tech Studio I work directly with founders and leadership teams, hands-on from day one. I advise, I lead, and I still write code every week.
Outside work, I'm a former ultramarathon runner and a musician.

Services
What we do
From a five-page website to a team of AI agents: five areas, one senior team.
Web Development
Websites for small businesses and tradespeople. Designed, built, found on Google, and cared for.
App Development
Custom mobile and web apps for any purpose, on any device. From first release to the app stores.
AI Implementation
Practical AI implementation: automate the processes that eat your team's week, with measurable results.
Engineering
Senior engineers for MVPs, feature delivery, and platform modernisation. We scope it, build it, ship it.
Technical Leadership
Senior technical leadership a few days a month: strategy, hiring, architecture, and delivery that ships.
For founders
Built most of your app and hit a wall?
Lovable, Replit, Bolt, or a small team that moved on: you got most of the way there, then progress stalled. We pick up from exactly where you are, not from scratch.
- Diagnostic first, no rewrite pitch
- NDA signed before we open a single file
- Three routes: a report, a fix, or an equity partner
Featured case studyRead the case study
JustPayMe on WhatsApp
Chasing an unpaid invoice is the job nobody wants. It is awkward, easy to delay, and the cost lands in cash flow. We built JustPayMe so the whole chase runs inside WhatsApp. The owner sends a message or voice note, approves with one tap, and a professional reminder goes to the client. The client can reply and pay straight from the chat. No new app, no portal to log into, on either side.
Making a messaging channel trustworthy enough to run money is the real work. The right tone at each step in the cycle, a human approving every send, careful delivery so nobody is chased twice or after they have already paid - that judgement is what the case study is about.
