This product-centric mindset, honed through roles at companies like Croissant and Printify, ensures APIs are robust, scalable, and aligned with user needs.
Tom's background includes significant work on large-scale platforms, such as contributing to the Printify design system ahead of its merger with Printful, supporting over 10 million merchants and approximately 60 frontend engineers. This experience in high-traffic environments informs his GraphQL API development, emphasizing efficient data fetching, caching strategies, and schema design that prevents common pitfalls like over-fetching or n+1 query problems. He is adept at collaborating with frontend teams to design APIs that empower product development.
GraphQL API Development for Modern Applications
GraphQL has revolutionized how applications consume data by providing a flexible, efficient query language that allows clients to request exactly what they need. As a GraphQL API developer, Tom specializes in designing and implementing GraphQL schemas that are intuitive, performant, and scalable. His work ensures that both web and mobile applications can fetch complex, nested data in a single request, reducing latency and improving user experience. This is particularly valuable for data-intensive platforms, such as e-commerce systems or SaaS products, where performance directly impacts conversion and retention.
Tom's approach to GraphQL API development integrates strongly with TypeScript, enabling end-to-end type safety from the backend schema to the frontend queries. This practice minimizes runtime errors, enhances developer productivity, and ensures that API changes are reflected immediately in the client code. He has applied this methodology in various contexts, including at Fream, where he led frontend development for industrial SaaS, integrating design systems and maps with robust backend APIs. The result is a cohesive system where data flows predictably and reliably.
Beyond basic CRUD operations, Tom engineers GraphQL APIs to handle advanced features like real-time subscriptions, file uploads, and complex authorization rules. He is skilled in setting up GraphQL servers using technologies like Apollo Server or GraphQL Yoga, and integrating them with databases such as PostgreSQL via ORMs or query builders. His experience at Websoul, a fintech SaaS he founded serving over 32,000 businesses, involved building marketing automation platforms with Vue, TypeScript, and Supabase, where efficient data handling via APIs was critical to system performance and scalability.
Integrating GraphQL with Full-Stack and Design Systems
A GraphQL API does not exist in isolation, it powers the entire application stack. Tom's full-stack proficiency allows him to seamlessly integrate GraphQL APIs with frontend frameworks like Angular, React, and Vue.js, as well as with comprehensive design systems. At Printify, his work on the design system and rebrand involved ensuring that the GraphQL API efficiently served component data and theme configurations to a large engineering team, supporting consistency and rapid iteration across the platform. This integration is key for maintaining a unified user experience at scale.
In practice, this means designing GraphQL schemas that expose design tokens, component prop interfaces, and content structures in a structured way. Tom leverages tools like GraphQL Code Generator to automatically produce TypeScript types and React/Angular/Vue query hooks from the schema, creating a tight feedback loop between backend and frontend development. This automation reduces boilerplate, prevents discrepancies, and accelerates feature development. It’s a methodology he has also applied in earlier roles, such as at industrial ERP provider Insoft Serwis, where system reliability and data accuracy were paramount.
Furthermore, Tom ensures that GraphQL APIs are accessible and well-documented, often using tools like GraphQL Playground or Apollo Studio to provide interactive exploration for developers. He emphasizes clear naming conventions, descriptive field-level documentation, and versioning strategies that allow for backward-compatible evolution. This focus on developer experience (DevEx) is crucial when working with distributed teams, as it reduces onboarding time and fosters collaboration. His remote work style, effective across EU, UK, and US time zones, relies on such clear, async-friendly communication tools and practices.
Scalability, Performance, and Security in GraphQL
Building a GraphQL API that performs under load requires careful attention to scalability, performance tuning, and security. Tom employs strategies such as query complexity analysis, depth limiting, and persisted queries to protect against malicious or inefficient queries that could degrade server performance. He implements efficient data loading patterns, using DataLoader to batch and cache database requests, thereby solving the n+1 query problem common in GraphQL resolvers. These techniques are essential for high-traffic applications, like those he worked on at Croissant, a workplace platform where compliance and collaboration features demanded reliable, fast data access.
Performance optimization also extends to caching at multiple levels. Tom configures HTTP caching headers for GraphQL responses where appropriate and integrates with CDNs or Redis for persistent caching of frequently accessed data. He monitors API performance using observability tools to identify bottlenecks in resolver execution or data fetching. This proactive approach ensures that the GraphQL API remains responsive as user bases grow, a consideration vital for startups scaling into enterprises or for platforms like Websoul that handle significant transactional data for thousands of businesses.
Security is another critical pillar. Tom implements authentication and authorization directly within the GraphQL context, using JWT tokens or session-based auth to secure queries and mutations. He defines granular permissions at the field or type level, ensuring users only access data they are entitled to see. His experience across industries, including with clients like GE Healthcare, Unilever, and Bunge, has ingrained a strong sense of data governance and regulatory compliance, which he applies to API design. This holistic view of security, performance, and scalability makes him a trusted partner for sensitive or business-critical applications.
From Legacy Systems to Modern GraphQL APIs
Many organizations grapple with legacy REST APIs or monolithic backends that hinder agility. Tom specializes in modernizing these systems by introducing GraphQL as a unified data layer. This process involves creating a GraphQL schema that aggregates data from various existing sources, such as REST endpoints, gRPC services, or direct database access, without requiring a full rewrite. He has undertaken such modernization efforts in previous roles, incrementally improving system architecture while maintaining business continuity. This strategy reduces risk and allows teams to gradually adopt new patterns.
A key part of this transition is designing a GraphQL API that serves as a facade for legacy systems, providing a cleaner, more consistent interface for frontend clients. Tom uses schema stitching or federation techniques to combine multiple GraphQL services or to wrap REST APIs with GraphQL resolvers. This approach was valuable in projects for public sector clients like the Polish Tourism Organisation and the Marshal Office of the Silesian Voivodeship, where integrating disparate data sources into a coherent API was essential for public-facing digital services. The result is a more maintainable and developer-friendly backend.
This modernization work is always paired with a focus on team enablement. Tom documents the Graph API thoroughly, creates example queries and mutations, and often conducts workshops to upskill engineering teams on GraphQL best practices. His background in technical writing, including earlier work at Webhosting.pl and authoring technical books, equips him to communicate complex concepts clearly. Whether the goal is to incrementally refactor an old ERP system or to build a new AI-integrated SaaS from scratch, Tom ensures the GraphQL API becomes a solid foundation for future growth.
When This is a Good Fit
Hiring Tom as your GraphQL API developer is an excellent fit if you are a founder, CTO, or technical leader building or scaling a web or mobile application that requires a robust, scalable data layer. It is ideal if you need a senior engineer who can take ownership of the entire API lifecycle, from schema design and implementation to performance optimization and team mentorship. This engagement works well for remote-first teams in the EU, UK, or US seeking a product-minded engineer who bridges technical execution with business strategy, ensuring your GraphQL API directly supports your product goals and user experience.
