About

My focus goes beyond writing code. I want to help my team ship faster. - To deliver, and help the team deliver. - To level up not just myself, but my entire team. - To create value by shipping faster. - To deploy small changes early and often. - To automate the redundant tasks, checks and testing. - To improve CI/CD pipelines so changes flow faster with confidence. - To build and design fault-tolerant systems that are robust and scale effortlessly - To help define and refine our teams ways of working. - To work closely with stakeholders and across teams. During my years in top-tier consultancy, I’ve delivered solutions for clients across various business domains. This experience has helped me become a flexible thinker and quick to adapt to changing needs. It has also taught me that my most energising and best work comes from deep, focused involvement in a single product. With a full-stack skill set and as a certified AWS Solutions Architect, I have a comprehensive understanding of what it takes to build robust and scalable applications from end to end. My goal is to create systems that are not just functional, but also a pleasure to use and maintain, while having fun solving complex challenges. I am always learning and am particularly excited to apply my skills in building scalable systems to the next generation of product challenges, including those in the Generative AI and LLM space.

My 8+ years as a consultant have been defined by building high-quality products for diverse clients. While I've worked in many teams, one made its mark.
In a 6-person team, I helped manage, at its peak, 8 applications for 8 different clients simultaneously. This intense environment honed my ability to prioritise, master context-switching, and drive results. It forced us to develop new "ways of working". From automating tasks, improving CI/CD, and building maintainable systems to create value, not manage chaos.
I formalized this approach by creating and leading internal workshops on "Writing Maintainable Code," which was adopted as a company best practice. I bring this hard-won philosophy of shipping faster and smarter to everything I build.
Here are a few key projects:
E-commerce Growth for a Major Finnish Retailer: Built core backend APIs and microservices to support a massive increase in online orders, contributing to a platform that won a national award.
Application Modernization for a Major Finnish Public Sector Entity: Led the refactoring of an unstable legacy app and built a new E2E test suite. This made the app dramatically more stable, enabling the team to ship features faster.
Homepage Modernization for a Global Gaming Company: Rebuilt a high-traffic homepage (millions of daily visitors), integrating a new headless CMS. This improved site performance and made it much faster for marketing to launch new content.
Strategic Platform Migration for a Major European Food Delivery Platform: Executed a critical HR platform migration with zero downtime and built new automated email workflows, improving the candidate experience and HR's operational efficiency.
Mobile App From Scratch for a Finnish Real Estate Agency: In a 3-dev team, co-designed the architecture and built a full-stack iOS enterprise app (backend, APIs, UI), moving from a Figma design to a full production app in under 6 months.
