// Two Red Kites — Engineering Profile
Wagner A
Senior Software Engineer
10+ years turning legacy nightmares into scalable, modern systems.
Legacy Moderniser
Senior Software Engineer at Two Red Kites with over a decade of experience building and modernising production systems across E-Commerce, Retail, and Finance. Inherits the systems others are afraid to touch and makes them safe, fast, and extensible again. Core work lives at the intersection of system rescue, sustainable architecture, and AI-augmented engineering workflows.
Tech Stack & Expertise
AI & Automation
Tooling I use to deliver faster, smarter, and with higher quality.
The Big Win
Monolith Rescue
From Maintenance Mode to Feature Velocity
Inherited a Rails monolith where years of accumulated shortcuts had ground feature development to a halt. Every change risked regressions. Velocity had collapsed. Mapped the debt systematically, introduced disciplined refactoring in parallel with delivery, and rebuilt the team's confidence in the codebase. Features that previously took weeks to scope and ship returned to normal cadence.
Industries
E-Commerce & Retail
Payment flows, subscription billing, inventory consistency, and the performance demands that come with real transaction volume.
Finance & FinTech
Financial systems where reliability isn't a nice-to-have.
Legacy Modernisation
Walking into codebases paralysed by technical debt and leaving teams able to ship again, not by rewriting everything, but by making targeted, high-leverage changes.
Outside the Code
"I rescue production systems that are too important to rewrite and too broken to extend."
