Your competitors are shipping. Your codebase is getting in the way.

YAGNI.IO embeds a Principal Engineer and Solution Architect directly into your product cycle — cutting scope, eliminating debt, and shipping what actually matters. Backend · Cloud · Mobile.

Services

Architecture & Code Review

Your architecture is making decisions for you — and usually the wrong ones. We map every risk, bottleneck, and ticking time bomb before it costs you a launch.

Cloud Architecture

Most teams pay three times more for cloud than their traffic justifies. We engineer AWS and GCP infrastructure that scales to real load without the waste — IaC, serverless, containers.

Backend & APIs

Leaky APIs and fragile services are where growth stalls. We build Python and Go backends that hold up under pressure and don't require anyone to stay up at night babysitting deployments.

Frontend Development

Slow frontends lose customers before they ever see your product. We build React and TypeScript interfaces that load fast, integrate cleanly, and don't quietly rot into unmaintainable chaos.

Mobile Development

Two separate native apps means double the maintenance, double the risk. We build React Native and FlutterFlow apps that perform like native without the duplicate overhead.

Tech Lead / Solution Architect

Your senior engineers are burning cycles on decisions that belong to a Tech Lead. We carry the architectural weight, align every technical choice to what ships, and keep the team pointed forward.

About

Over a decade designing and delivering cloud-native systems at scale. Specializing in the architecture decisions that determine whether a product survives its own growth — backends, cloud infrastructure, and platform engineering built on Python, Go, AWS, and GCP.

Daily role: Tech Lead embedded with product teams through the full delivery lifecycle — architecture, technical strategy, hands-on implementation, and the hard conversations that keep systems aligned with business outcomes. YAGNI.IO currently works with Xebia. Capacity is limited and intentionally kept that way.

Contact

YAGNI.IO works with a small number of teams at any given time. If you are building something that needs to survive real scale, reach out via LinkedIn with a brief description of the problem. Fit matters more than timeline.

What to include:

  • What you’re building and where it’s breaking down
  • The type of support you need — architecture, delivery, or both
  • Your expected timeline and engagement type

We respond within 1–2 business days. Not every engagement is the right fit — and we'll tell you that directly.
