Tom Smykowski is a senior frontend engineer with nearly two decades of product delivery, specializing in building secure, compliant web applications for companies across the EU, UK, and US. Hiring him is ideal for teams that need a product-minded engineer who integrates security and compliance considerations directly into the frontend architecture and user experience from the ground up. He combines hands-on engineering with strategic product thinking to deliver robust applications that protect user data and meet regulatory standards.
Why Security in Frontend Engineering is Non-Negotiable
In today's digital landscape, frontend security is a critical pillar of any application's integrity. The frontend is the user-facing layer, handling sensitive data, authentication flows, and user inputs, making it a prime target for attacks. A security-focused approach is not just about patching vulnerabilities, it's about designing systems where security is a foundational principle, not an afterthought.
Tom's experience spans industries with stringent compliance needs, such as fintech, healthcare, and enterprise SaaS. This background ensures he understands the real-world implications of security lapses and the importance of building applications that are not only functional but also trustworthy and resilient. His work prioritizes secure coding practices, data validation, and robust client-side logic to mitigate risks like XSS, CSRF, and data leakage.
For teams in the EU, UK, or US, navigating regulations like GDPR, CCPA, or industry-specific standards adds another layer of complexity. Tom's remote work model from Poland, with effective overlap across these time zones, allows him to integrate seamlessly with your team to implement frontend solutions that are both technically secure and compliant with relevant legal frameworks.
Building Secure and Compliant User Interfaces
Creating a secure user interface involves more than just aesthetic design. It requires a deep understanding of how users interact with the application and where potential security pitfalls may arise. Tom employs a UX-driven security approach, ensuring that security measures enhance, rather than hinder, the user experience.
His projects, such as the workplace platform for Croissant and the marketing automation SaaS at Websoul, demanded high levels of data protection and user privacy. By implementing secure design patterns and rigorous input validation, he helped build interfaces that users could trust. This involves careful management of authentication states, secure handling of tokens and sessions, and clear user feedback for security-related actions.
Furthermore, Tom leverages modern frameworks like Vue.js and TypeScript to enforce type safety and reduce runtime errors that could lead to vulnerabilities. His work on design systems, such as at Printify, includes establishing secure component libraries that standardize safe practices across large engineering teams, ensuring consistency and reducing the risk of developer-introduced security flaws.
Architecting Frontends for Security and Scale
Security architecture at the frontend level involves strategic decisions about state management, API communication, and dependency management. Tom's role as a staff or lead engineer involves making these architectural choices with security and long-term maintainability in mind. He designs systems that are secure by default.
At Printify, working within a team of around 60 frontend engineers, architectural decisions had to support security at scale. This meant establishing clear patterns for API consumption, error handling, and state persistence that prevented common vulnerabilities. His experience with full-stack development, including backend technologies like Supabase, gives him a holistic view of the data flow, allowing him to secure the frontend in the context of the entire application ecosystem.
For projects involving complex data grids and enterprise features, such as those using AG Grid at Websoul, security extends to controlling data access and ensuring that client-side rendering does not expose sensitive information. Tom's approach ensures that even the most feature-rich frontends maintain a strong security posture as they scale to serve millions of users, as seen with Printify's platform for over 10 million merchants.
Integrating Security into the Development Lifecycle
A security-focused mindset must be embedded throughout the software development lifecycle. Tom advocates for and implements practices that make security a continuous concern, from initial discovery through to production monitoring. This includes integrating security checks into CI/CD pipelines, conducting regular code audits, and fostering a culture of security awareness within the team.
His consulting and audit services, such as code and architecture reviews, are directly applicable here. He can assess existing frontend codebases for security vulnerabilities, recommend improvements, and help set up automated testing for security regressions. This proactive approach is far more cost-effective than reacting to breaches after deployment.
Tom also incorporates AI-assisted tools and workflows to enhance security testing and code analysis, staying ahead of emerging threats. By combining traditional secure development practices with modern AI tooling, he helps teams build more resilient applications efficiently. His ability to conduct remote workshops and training means he can uplift the entire team's capability in secure frontend development.
Case Studies in Secure Frontend Delivery
Tom's portfolio demonstrates a consistent track record of delivering secure frontend solutions. At Croissant, as a Staff Software Engineer, he worked on a platform requiring robust compliance and collaboration features, where security of user data and workspace access was paramount. This involved complex frontend logic to manage permissions and secure real-time updates.
As the founder of Websoul, he built a fintech SaaS from the ground up, handling sensitive business and marketing data for over 32,000 businesses. The frontend architecture needed to ensure data integrity and privacy, utilizing Vue.js, TypeScript, and Supabase to create a secure, full-stack application. The use of AG Grid for data presentation required careful security configuration to prevent client-side data exposure.
Earlier in his career, working on industrial ERP systems at Insoft Serwis, he dealt with enterprise-level data security requirements. This foundational experience in business-critical software instilled the importance of reliability and security, principles he carries into all modern frontend work. These diverse experiences across startups, scale-ups, and enterprise clients provide him with a unique perspective on implementing security measures that are appropriate for the business context and risk profile.
When This is a Good Fit
Engaging Tom as your Security-Focused Frontend Engineer is an excellent strategic move if your project involves handling sensitive user data, operates in a regulated industry, or simply cannot afford the reputational damage of a security breach. He is the right fit for teams that need a senior engineer who can own the security aspect of the frontend, from architecture and implementation to team mentorship and process improvement. His remote collaboration model from Poland is optimized for working with EU, UK, and US East Coast teams, making him a valuable asset for internationally distributed companies prioritizing application security.
