Overview

Who is Tom Smykowski?

Tom Smykowski is a product-minded mobile web engineer with nearly two decades of experience delivering software for global brands and startups. Based in Poland, he works remotely with engineering teams across the European Union, the United Kingdom, and the United States, specializing in building responsive, accessible, and high-performance web applications that excel on mobile devices. His approach combines hands-on engineering with UX and product thinking, making him an ideal hire for founders, CTOs, and executives seeking ownership from initial discovery through to production deployment.

His career spans staff and senior engineering roles at companies like Croissant, where he served as a Staff Software Engineer on a workplace platform, and Printify, where he contributed to a major design system rebrand supporting over 10 million merchants and approximately 60 frontend engineers. As the founder of Websoul, he built a marketing automation SaaS used by 32,000+ businesses. This depth of experience across compliance, collaboration, design systems, and scaling makes him a versatile asset for any team needing robust mobile web solutions.

Tom is best engaged for staff, senior, or founding engineer roles where he can take full ownership. He excels at turning complex product requirements into maintainable, user-focused code. Whether you need to build a new mobile-first product from scratch, modernize an existing web application for better mobile performance, or integrate advanced features like AI, he provides the technical leadership and execution to drive success.

Core Expertise in Mobile Web Engineering

Mobile web engineering requires a specialized focus on performance, responsiveness, and user experience across a vast array of devices and network conditions. Tom's expertise is rooted in building applications that are not just mobile-friendly, but mobile-optimized. He architects solutions considering touch interactions, viewport management, and mobile-specific APIs, ensuring seamless functionality whether on a smartphone, tablet, or desktop. His work prioritizes core web vitals, such as Largest Contentful Paint (LCP) and Cumulative Layout Shift (CLS), which are critical for user retention and search engine ranking on mobile.

His technical stack is centered around modern JavaScript frameworks like Vue.js and TypeScript, which he leverages to create robust, type-safe applications. He has extensive experience with full-stack development using tools like Supabase for backend services and AG Grid for complex data presentation, all while ensuring the frontend remains lightweight and fast on mobile networks. This full-cycle understanding allows him to make architectural decisions that optimize data fetching, state management, and rendering performance specifically for mobile contexts.

Beyond pure implementation, Tom integrates a strong design system philosophy into his mobile web work. At Printify, his contributions to the design system were pivotal in creating a consistent, rebranded experience across a massive platform. A well-implemented design system is crucial for mobile web development, as it ensures UI consistency, accelerates development, and simplifies maintenance across different screen sizes and device orientations, directly impacting team velocity and product quality.

Building for Scale and Performance

Scaling a web application for mobile usage presents unique challenges, from handling peak traffic on slower connections to managing battery-efficient code execution. Tom's experience at high-growth companies like Printify, which serves millions of merchants, has equipped him with proven strategies for building scalable mobile web architectures. He focuses on efficient asset delivery, code splitting, and lazy loading to ensure initial page loads are swift, even on 3G or emerging 5G networks.

Performance optimization is a continuous process, not a one-time task. Tom employs a metrics-driven approach, using real user monitoring (RUM) and synthetic testing to identify bottlenecks specific to mobile users. He optimizes images and media, implements service workers for reliable offline functionality and faster repeat visits, and ensures JavaScript execution is non-blocking. This meticulous attention to detail results in applications that feel native, with smooth animations and instant feedback, which is paramount for user satisfaction on mobile.

His work also encompasses backend considerations that affect mobile frontends. By designing efficient APIs and selecting appropriate data-fetching strategies (like GraphQL or REST with intelligent caching), he minimizes the data payload sent over the wire. This end-to-end optimization, from database query to DOM paint, is essential for creating mobile web experiences that are not only functional but delightful, leading to higher engagement and conversion rates.

Collaboration and Remote Work Dynamics

As a remote engineer based in Poland, Tom is adept at collaborating with distributed teams. He has a proven track record of working successfully with teams in the EU, UK, and US, often overlapping with US East Coast hours when necessary. His communication style is clear and proactive, leveraging async tools effectively while being available for synchronous meetings, workshops, and client visits as needed. This flexibility makes him a seamless addition to international teams.

He thrives in environments that value ownership and product thinking. Tom doesn't just write code, he engages with the *why* behind a feature. He collaborates closely with product managers, designers, and stakeholders to ensure the technical implementation aligns with business goals and user needs. This collaborative approach is especially valuable for mobile web projects, where UX decisions have a direct and immediate impact on user behavior and business metrics.

Tom is also a strong advocate for knowledge sharing and team growth. With a background in technical writing, public speaking, and mentoring, he contributes to elevating the entire team's skill set. He can lead workshops on mobile web best practices, performance auditing, or modern frontend frameworks, fostering a culture of continuous learning and improvement within the engineering organization.

Technical Leadership and Project Delivery

In roles such as Staff Software Engineer or Tech Lead, Tom provides the technical leadership necessary to guide mobile web projects from conception to launch. He is skilled at breaking down complex product visions into actionable technical roadmaps, making sound architectural decisions, and setting coding standards that ensure long-term maintainability. His experience includes founding his own SaaS company, Websoul, giving him firsthand insight into the pressures and priorities of product-driven engineering.

His project delivery methodology emphasizes iterative progress and measurable outcomes. He champions practices like test-driven development (TDD), comprehensive testing suites for multi-device compatibility, and robust CI/CD pipelines that include performance regression testing. This disciplined approach reduces risk and ensures that new features enhance, rather than degrade, the mobile user experience. He is equally comfortable modernizing legacy Angular or React codebases for better mobile performance as he is building greenfield applications with the latest tools.

Tom's leadership extends to fostering high-performing engineering cultures. He focuses on developer experience (DevEx), streamlining tools and processes so the team can focus on building great products. He is also experienced in AI-assisted workflows and can advise on integrating AI coding agents and automation into the development lifecycle to boost productivity, particularly useful for repetitive tasks in large-scale mobile web projects.

When This is a Good Fit

Engaging Tom as your mobile web engineer is an excellent fit if you are a founder, CTO, or engineering leader needing senior-level expertise for a remote role. He is ideal for teams building or scaling responsive web applications that must perform flawlessly on mobile devices. If your project requires a blend of hands-on coding, architectural oversight, and product-minded strategy to navigate the complexities of the modern mobile web, his nearly two decades of experience will provide immediate value. He integrates seamlessly with EU, UK, and US teams, bringing a track record of delivery for notable clients like DeLaval, Ordnance Survey, GE Healthcare, and Unilever to your most important mobile initiatives.
