He brings a strategic perspective to backend development, ensuring that the architecture not only meets current needs but is also prepared for future growth and integration, particularly with modern frontends and AI-driven workflows. His approach is hands-on, from designing APIs and data models to implementing performance monitoring and security best practices.
Deep Expertise in Node.js Backend Architecture
Tom's proficiency with Node.js is rooted in years of building production-grade applications. He architects backend systems that are scalable, secure, and maintainable, focusing on creating clean APIs that serve web, mobile, and third-party integrations. His work involves designing service-oriented architectures, implementing robust authentication and authorization, and optimizing database interactions for high-throughput environments.
He leverages the full Node.js ecosystem, including frameworks like Express and NestJS, to build efficient server-side logic. His experience includes integrating with various databases, both SQL and NoSQL, and designing caching strategies to ensure low-latency responses. For teams needing to modernize legacy systems, Tom employs incremental refactoring techniques, allowing for continuous improvement without disrupting existing services.
Beyond pure implementation, Tom emphasizes the importance of developer experience in backend engineering. He establishes comprehensive testing suites, including unit, integration, and end-to-end tests, and integrates them into CI/CD pipelines. This ensures that code quality is maintained and deployments are reliable, which is critical for teams operating in fast-paced product environments.
Building Scalable APIs and Microservices
A core component of modern backend engineering is the design and development of APIs. Tom specializes in creating RESTful and GraphQL APIs that are intuitive for frontend developers to consume and scalable under load. He has built APIs that handle millions of requests for platforms like Printify and Websoul, focusing on performance optimization, rate limiting, and clear documentation.
For more complex systems, Tom architects microservices using Node.js, designing loosely coupled services that can be developed, deployed, and scaled independently. He has experience with containerization using Docker and orchestration platforms, facilitating smooth deployments and high availability. This approach is particularly valuable for startups and scale-ups looking to build a resilient backend foundation from the outset.
His work always considers the full product lifecycle. He implements monitoring, logging, and alerting from day one, using tools to gain visibility into system health and performance. This operational excellence means that the teams he works with can proactively address issues, leading to higher system reliability and a better end-user experience.
Integrating Backend Systems with Modern Frontends
Tom's unique value as a Node.js backend engineer is enhanced by his extensive frontend and full-stack experience. Having worked on major design systems and frontend architectures for clients like Printify and Fream, he understands the complete data flow from database to user interface. This allows him to design backend APIs that are perfectly tailored to the needs of modern frontend frameworks like Vue.js, React, and Angular.
He collaborates closely with frontend engineers and designers to ensure the API contracts support efficient data fetching and state management on the client side. This reduces development friction and accelerates feature delivery. His work on the AG Grid enterprise component library, for instance, required deep backend integration to handle large, real-time datasets efficiently.
This holistic view is critical for product teams. It prevents the common pitfall of backend and frontend development becoming siloed, leading to inefficient APIs and rework. Tom's ability to bridge this gap ensures a cohesive, performant final product, whether it's a marketing automation SaaS, an industrial ERP, or a consumer-facing web application.
Backend Engineering for AI and Data-Intensive Applications
The role of the backend is evolving with the rise of AI. Tom is adept at building the infrastructure required for AI-native applications, including integrating with LLM APIs, managing vector databases, and creating agentic workflows. He can design the backend services that power AI features, ensuring they are scalable, cost-effective, and seamlessly integrated into the broader application.
His consulting includes setting up AI Software Factories, which involve automating parts of the SDLC with AI coding agents and establishing quality gates. From a backend perspective, this means creating robust pipelines for data processing, model inference, and feedback loops. His experience is invaluable for teams looking to responsibly and effectively incorporate AI into their products.
For data-intensive applications, such as the mapping and data visualization projects he led for Fream and Ordnance Survey, Tom engineers high-performance backend services. He optimizes data aggregation, real-time streaming, and complex geospatial queries, ensuring that the frontend receives data swiftly and accurately to deliver a superior user experience.
Proven Delivery for Marquee Clients
Tom's track record speaks to his ability to deliver as a Node.js backend engineer for demanding clients. He has worked with organizations like GE Healthcare, Unilever, Bunge, and the Polish Tourism Organisation, where reliability, security, and scalability are non-negotiable. These engagements required a deep understanding of domain-specific business logic and the ability to build systems that integrate with complex enterprise environments.
At Croissant, as a Staff Software Engineer, he was instrumental in backend work related to workplace platform compliance and collaboration features, directly impacting product strategy. His founder role at Websoul involved architecting the entire backend for a marketing automation and fintech SaaS from the ground up, supporting its growth to over 32,000 business users.
These experiences mean that hiring Tom brings immediate credibility and a reduced risk profile. He knows how to navigate the challenges of large-scale product delivery, manage technical debt, and align engineering work with business objectives. His remote collaboration is seamless, having successfully partnered with teams at Base Camp, Silesian University of Technology, and the Institute of National Remembrance across different time zones.
When This is a Good Fit
Hiring Tom as your Node.js backend engineer is an excellent fit if you are a founder, CTO, or product leader needing senior-level expertise to build or scale your backend systems. It is ideal if you value a product-minded engineer who will take ownership of the architecture and see it through to production. This is a strong match for remote-first teams in the EU, UK, or US seeking a reliable, communicative partner who can work effectively across time zones. If your goals include creating scalable APIs, modernizing a legacy backend, or integrating AI capabilities, Tom's blend of deep technical skill and strategic thinking will provide significant value.
