Get a custom proposalReliable custom software for the AI era
Mile Development (mile.dev) is a custom software development company built for the AI era. AI accelerates our delivery while senior engineers stay accountable for architecture, security, and long-term maintainability. We are not a generic outsourcing vendor or a loose freelancer network. We are a focused engineering team that helps companies build software with clarity, reliability, and ownership.
We work with companies across the EU, UK, and US that need serious software systems, with a particular strength in taking over, stabilizing, and modernizing existing products, then continuing to build on top of them.
What we build
- Custom software: SaaS platforms, CRM and business systems, internal tools, marketplaces, and automation
- Mobile apps: native iOS and Android, and cross-platform with Flutter
- Backend and architecture: scalable, multi-service systems, complex integrations, IoT and data platforms
- AI-enabled features applied to production data
- Modernization and takeover: stabilizing and improving existing systems before continuing development
How we work
- Clarity before coding. Projects fail when expectations are unclear.
- Estimation is an engineering responsibility, not a sales tool. We give structured time-range estimates based on scope and complexity, not optimistic fixed-price promises.
- Transparent delivery: documented tasks, logged time, visible progress.
- Low-pressure consultation. Send us the project details and we respond with a structured technical review and an estimate range, usually within 2 to 3 business days. No forced sales calls.

Our Story
Mile Development started in 2019 as a small team of senior engineers who wanted to build software the right way: clear scope, honest estimation, real ownership. Over the years we became the team companies call to take over, stabilize, and modernize products that outgrew their original build. Today we work with clients across the EU, UK, and US, combining AI-accelerated delivery with senior engineering judgment on architecture, security, and long-term maintainability.

I am the founder and CTO of mile.dev. I started in iOS development and grew into architecture, estimation, and technical leadership, and stayed hands-on with architecture at the start of every project.

What Sets Us Apart
Senior engineering ownership
AI speeds up our work, but senior engineers stay accountable for architecture, security, and long-term maintainability. You get judgment and ownership on the decisions that determine whether software survives in production, not just code that runs today.Takeover and modernization
We are often brought in to rescue products that outgrew their original build. We stabilize existing systems, refactor and modernize them, migrate infrastructure, and then keep building, so you move forward without starting over.Estimation is engineering, not sales
We give structured time-range estimates based on real scope, architecture, and complexity, not optimistic fixed-price promises. Delivery is transparent: documented tasks, logged time, and visible progress you can follow.Locations (1)
