Why Hire a NestJS Backend Engineer?
Tom Smykowski is a product-minded senior backend engineer with nearly two decades of experience in software delivery, specializing in building and scaling backend systems with NestJS. He is the ideal hire for founders, CTOs, and executives seeking an engineer who can take ownership from architectural discovery through to production deployment. Tom combines deep backend expertise with product thinking and UX awareness, ensuring the systems he builds are not only technically sound but also drive business value. He works remotely from Poland, collaborating effectively with teams across the EU, the UK, and the US, including overlapping with US East Coast time zones.
NestJS has emerged as a powerful framework for creating efficient, reliable, and scalable server-side applications. It provides an out-of-the-box application architecture that allows developers and teams to create highly testable, scalable, loosely coupled, and easily maintainable applications. Hiring a dedicated NestJS backend engineer like Tom means bringing on someone who understands this architecture deeply and can leverage it to accelerate development, enforce best practices, and build systems that stand the test of time. His experience spans from greenfield projects to modernizing legacy systems, always with a focus on maintainability and performance.
In today's competitive landscape, the backend is the engine of your product. A poorly architected API can cripple user experience and limit growth. Tom's approach ensures your backend is a strategic asset. He focuses on creating clean, well-documented APIs, robust data models, and efficient integration patterns. His work with teams at companies like Printify, Croissant, and GE Healthcare demonstrates his ability to handle complex requirements and high-scale environments, making him a strong candidate for your next backend engineering role or project.
Expertise in NestJS and Modern Backend Architecture
Tom's proficiency with NestJS goes beyond basic usage. He leverages its modular architecture, dependency injection, and extensive ecosystem to build enterprise-grade applications. He is adept at structuring projects for scalability, implementing microservices patterns when appropriate, and ensuring seamless integration with databases, message queues, and third-party services. His work is characterized by clean separation of concerns, comprehensive testing strategies, and a commitment to code quality that reduces technical debt from the outset.
His backend expertise is complemented by a strong command of TypeScript, which is foundational to the NestJS experience. This ensures type safety, better developer tooling, and fewer runtime errors. Tom architects systems with clear contracts between modules, making the codebase understandable for other engineers and easier to extend. He is experienced in setting up the full backend lifecycle, including database design with ORMs like TypeORM or Prisma, implementing authentication and authorization (including JWT, OAuth), and designing RESTful and GraphQL APIs tailored to client needs.
Furthermore, Tom understands that a backend is part of a larger system. He considers deployment strategies, containerization with Docker, orchestration, monitoring, and logging from the start. His experience in product delivery means he always considers the operational aspects of the software he builds. This holistic view ensures that the systems he delivers are not only functionally complete but also operationally robust and easy to maintain in production, which is critical for long-term success.
Building Scalable APIs and Microservices
Scalability is a non-negotiable requirement for modern applications. Tom has a proven track record of designing and implementing backend systems that can handle growth. At Printify, he contributed to a platform serving over 10 million merchants, requiring highly scalable and resilient backend services. This experience informs his architectural decisions, whether he's building a new MVP or refactoring an existing monolith into a more scalable microservices architecture.
When building APIs, Tom focuses on performance, security, and developer experience. He optimizes database queries, implements efficient caching strategies with Redis or similar technologies, and ensures API endpoints are paginated and filtered appropriately. He is skilled in building event-driven systems using message brokers, which are essential for decoupling services and building resilient, scalable applications. His work ensures that your backend can handle increased load without compromising on response times or reliability.
Security is integral to his development process. He implements industry-standard practices for data validation, sanitization, encryption, and secure communication (HTTPS/TLS). He is experienced in setting up role-based access control (RBAC) and ensuring compliance with data protection regulations relevant to your market. By building security in from the ground up, he helps protect your application and your users' data, which is paramount for building trust and avoiding costly breaches.
Integration with Frontend and Full-Stack Considerations
While specializing in backend engineering, Tom's extensive full-stack and frontend background, including significant work with Angular and Vue.js, makes him uniquely valuable. He understands the entire data flow from the database to the user interface. This allows him to design APIs that are intuitive for frontend developers to consume, with well-structured payloads, sensible error handling, and comprehensive documentation. He can collaborate effectively with frontend teams to define API contracts early in the development process, reducing integration friction.
His experience in building design systems and working on complex frontend applications at Printify and Fream means he appreciates the challenges on the client side. This empathy translates into backend designs that support rich user interfaces, real-time features via WebSockets, and efficient data fetching patterns. He can advise on state management strategies that span the frontend-backend boundary, ensuring a cohesive and performant user experience.
This full-stack perspective is particularly beneficial in smaller teams or startup environments where engineers often wear multiple hats. Tom can step in to assist with frontend tasks if needed, but more importantly, he ensures the backend serves as a solid foundation for the entire product. He avoids creating backend bottlenecks that would limit frontend innovation, enabling your team to build features faster and with greater confidence.
Collaboration and Remote Work with International Teams
Tom is based in Poland and has a long history of successful remote collaboration with teams across Europe, the UK, and North America. He is adept at asynchronous communication, clear written documentation, and effective use of collaboration tools. He can seamlessly integrate into your existing engineering processes or help establish best practices for remote teams. His ability to overlap with US East Coast hours facilitates daily stand-ups and real-time collaboration when needed.
He thrives in environments that value clear communication and shared ownership. As a former founder of Websoul and a staff engineer at Croissant, he is comfortable working directly with founders, product managers, and stakeholders to translate business requirements into technical specifications. He is not just an order-taker, he is a thought partner who asks probing questions to ensure the solution being built is the right one for the problem at hand.
His remote work style is proactive and transparent. He believes in regular updates, visibility into progress, and flagging potential blockers early. This makes him a reliable and predictable member of any distributed team. Whether your team is fully remote, hybrid, or based in a different country, Tom's experience ensures a smooth and productive collaboration.
When This is a Good Fit
Hiring Tom as your NestJS backend engineer is an excellent fit if you are a founder, CTO, or engineering lead looking for senior-level expertise to build or scale your backend infrastructure. He is ideal for teams that need someone who can take ownership of the backend domain, make sound architectural decisions, and execute with high quality. This is a strong match if you are building a new product with NestJS, modernizing a legacy backend system, or need to scale your APIs to handle increased traffic and complexity. If you value a product-minded engineer who understands the business impact of technical choices and can collaborate effectively in a remote, international setting, then Tom is the right candidate for your team.
