This background ensures he approaches fintech projects with a mindset geared towards risk mitigation, data protection, and system resilience from the outset.
Scalable Platform Engineering for Financial Products
Scaling a fintech application involves more than just handling increased traffic. It requires architectural decisions that support growth in transaction volume, user base, and feature complexity without compromising performance or security. Tom's track record includes leading frontend architecture for platforms like Printify, where he contributed to a design system used by 60+ frontend engineers serving 10 million+ merchants, demonstrating his ability to create maintainable systems at scale.
This experience is directly applicable to fintech, where clear abstractions, consistent APIs, and a well-structured codebase are paramount for team velocity and long-term sustainability. Whether modernizing a legacy monolith or building a greenfield microservices architecture, Tom focuses on creating systems that are not only functional today but are also built to evolve alongside the business, incorporating best practices in CI/CD, testing, and developer experience.
Full-Stack Proficiency with Modern Fintech Tech Stacks
Tom brings full-stack proficiency with the technologies modern fintech teams rely on. His expertise includes Vue.js, TypeScript, and Supabase for rapid, type-safe full-stack development, as well as complex data grid implementations using AG Grid for financial dashboards and reporting tools. This technical foundation allows him to contribute across the entire stack, from crafting responsive, accessible user interfaces to designing and optimizing backend services and APIs.
His approach is tool-agnostic and focused on selecting the right technology for the problem at hand. For fintech projects, this often means prioritizing technologies that offer strong typing, excellent developer tooling, and a mature ecosystem for security and data handling. He is adept at integrating third-party financial APIs, payment gateways, and data aggregation services, ensuring seamless and reliable connections within the broader financial ecosystem.
Enhancing Developer Experience and Team Productivity
In fast-moving fintech environments, developer productivity and reduced time-to-market are competitive advantages. Tom has a proven focus on improving developer experience (DevEx), having led initiatives in design systems, CI/CD implementation, and code quality automation. By establishing clear patterns, automated testing suites, and efficient deployment pipelines, he helps engineering teams ship features faster and with greater confidence.
This is particularly valuable in fintech, where regulatory changes and market demands require rapid iteration. Tom's experience includes setting up AI-assisted workflows and coding agents to further boost team efficiency. He understands that a high-performing engineering organization is built on a foundation of excellent tools and processes, and he brings that operational mindset to every engagement, whether as an individual contributor or a technical lead.
AI Integration and Modernization for Competitive Edge
The fintech sector is increasingly leveraging AI for fraud detection, personalized financial insights, risk assessment, and automated customer support. Tom's expertise in AI-native development and AI software factory setup positions him to help fintech companies integrate these technologies effectively. He can architect systems that incorporate large language models (LLMs) and machine learning models in a secure, scalable, and compliant manner.
Beyond greenfield AI projects, he is skilled in modernizing existing Angular or React applications, ensuring they are performant, maintainable, and ready to incorporate new AI-driven features. This dual capability in core platform engineering and cutting-edge AI application makes him a unique asset for fintech companies looking to innovate while maintaining a rock-solid technical foundation. His work with clients like GE Healthcare and Unilever on complex, data-intensive systems underscores his ability to handle sophisticated technical challenges.
When This is a Good Fit
Engaging Tom as your Fintech Software Engineer is an excellent fit if you are a founder, CTO, or executive leading a fintech startup or scale-up. It is ideal when you need a senior technical leader who can own the entire product delivery lifecycle, from architecting a secure and scalable platform to mentoring a team and implementing AI-driven features. His remote collaboration from Poland is seamless for teams in EU, UK, and US East Coast time zones.
