A software consultancy that ships

Software, engineered to scale.

We build performant, reliable systems for startups and enterprises — from the first prototype to the architecture that keeps it running at scale.

What we do

Five focused services.
No filler.

We don't claim to do everything. We do a few things well — and that's the point.

Custom software development

End-to-end product engineering. Web apps, internal tools, APIs, and platforms — built with the rigor of a product team, not a body shop.

build.ts

Mobile apps

React Native apps that feel native. Shared logic across iOS and Android with zero compromise on performance.

Systems architecture

Pragmatic, scalable architectures. Distributed systems, data pipelines, and platform foundations designed to last.

Performance

Audits and optimizations on hot paths. Cut p95 latency, slim bundles, fix the leaks others miss.

Consulting for startups & enterprises

Embedded engineering leadership. Architecture reviews, hiring, and the hard calls — without the overhead of a full-time hire.

About ueiv

A small team of senior engineers.
Not a body shop. Not a pitch deck.

We've been on both sides — building products inside startups, and unblocking platform teams inside enterprises. That perspective is the work.

Every engagement is led by a senior engineer. We write the code we ship. We document what we change. We measure what matters: latency, reliability, and the cost of running it on Monday morning.

No hand-offs. No churn. No surprises.

How we work

A predictable process for
unpredictable problems.

Four steps. Same shape every time. The work inside is never the same.

01

Discovery

We map the system, the constraints, and the real shape of the problem.

  • Stakeholder interviews
  • Codebase audit
  • Risk assessment
02

Planning

Clear scope, sharp milestones, and an architecture you can defend.

  • Technical spec
  • Milestones & SLAs
  • Tradeoff analysis
03

Development

Senior-led delivery with weekly demos, tests in the loop, and zero hand-offs.

  • Iterative shipping
  • Code review by default
  • Observability built in
04

Delivery

Production-ready, documented, monitored. We hand over a system, not a debt.

  • Runbooks & docs
  • Performance benchmarks
  • Knowledge transfer
Selected work

Real systems.
Real outcomes.

What clients say

Fewer reviews.
More repeat clients.

The audit alone paid for the engagement. They found three production issues we'd been chasing for months — and shipped fixes the same week.
Maya Chen
VP Engineering, Helios Labs
Senior end-to-end. No PMs translating, no juniors padding hours. We treated them like part of the team because they were.
Daniel Okafor
CTO, Strata
Rare combination of speed and rigor. The architecture they shipped two years ago still holds up — and we've 8x'd traffic since.
Lena Vassar
Founder, Vantage
