From prototype to production.
Merge Street is a team of senior product engineers. We build custom software, and we take AI-generated, rushed or inherited codebases and turn them into products you can scale. We care about why a feature exists, not just how to build it.

What we do
Custom software
Systems built around how your business actually works, handed over in full.
AI code cleanup & audits
We find what will break first in AI-generated and legacy code, and fix it without rewriting everything.
Backend & infrastructure
APIs, data models, queues and integrations, built for reliability.
Mobile & web
Cross-platform apps and web frontends that are fast, tested and maintainable.
DevOps & observability
CI/CD, infrastructure as code, and monitoring and alerting that fire on real problems, not noise.
// approach
How we think
Product engineers, not ticket takers.
We learn how your users use the product and how your business makes money. Then we build what moves it forward, and push back when a task doesn't.
Senior only.
You only work with experienced engineers who know what they're doing. The person on the call is the person writing the code.
Fix, don't rewrite.
Rewrites are rarely the answer. We keep what works.
Boring technology.
Proven tools over trendy ones, because your product has to run for years.
Yours, fully. Supported, long-term.
You own the code, the infrastructure and the documentation from day one. You can walk away at any time, but you don't have to: we support what we build for years, not weeks.
// work with us
Ways to work with us
Audit
A short, fixed-price review of your codebase and infrastructure, with a written report and a prioritized plan. The best place to start.
Project
A defined goal: build a custom system, stabilize the backend, ship the mobile app, set up infrastructure.
Team augmentation
Senior engineers embedded in your team, working in your tools and processes from week one.
Long-term support
After handover, a monthly retainer for maintenance, monitoring, security updates and improvements. The people who built it keep looking after it.
We usually start with an audit, then plan and ship in weekly iterations, with a full handover at the end.
