Offshore Development Center
OTS's flagship service is the Offshore Development Center model, a fully managed approach to building a dedicated R&D team in Poland on a long-term basis. Unlike traditional outsourcing, OTS handles everything on the ground: tech recruitment, HR, office space, payroll, and all back-office administration. Clients get a team of engineers, designers, and product talent that works exclusively on their product, never shuffled between projects or shared with other customers. The financial model is fully transparent: clients have complete visibility into what their engineers earn and exactly what management fee OTS charges on top, with no hidden markups. And should the partnership evolve, clients retain the contractual right to buy out their team from day one.
Custom Software Development
For companies that need an immediate engineering boost rather than a long-term team build, OTS offers on-demand custom software development. Their in-house team plugs directly into your existing stack and processes, covering the full development lifecycle, from frontend and backend to mobile, APIs, DevOps, QA, and technical consulting. Their web team works across .NET, Python, Node.js, Go, Ruby on Rails, React, and Angular, while mobile projects are handled in React Native, Flutter, Swift, and Kotlin. APIs are built with REST, GraphQL, and WebSockets; infrastructure is managed with Docker, Kubernetes, Terraform, and CI/CD pipelines; and QA is delivered through both manual and automated testing with Selenium and Playwright. A key differentiator here is that OTS's CTO personally oversees every custom development engagement, ensuring technical quality and alignment with client expectations at every stage.
CTO as a Service
For early-stage startups that need senior technology leadership without the cost of a full-time executive, OTS provides fractional CTO support on demand. This service is designed to take non-technical founders from idea and roadmap all the way through PoC, MVP, and beyond, helping them make the right technology choices, set up scalable architecture, manage development teams, and de-risk early engineering decisions. The fractional CTO brings hands-on involvement rather than advisory-only support, making them a practical extension of the founding team.
Community & Events
Beyond their client work, OTS runs TechSpot, a recurring event series for senior engineers and tech leaders in Warsaw, focused on real-world engineering challenges across AI and LLMs, cloud computing, DevOps, and system architecture. Speakers come from leading technology companies, and the format is designed for knowledge exchange and community building within the Polish tech ecosystem. They also produce the 137 Podcast, where OTS's co-founder sits down with CTOs, engineers, and founders to discuss the day-to-day realities of building software products.
