Paweł Dymek
Full-Stack Software Engineer
20+ years of shipping production-grade software that drives ROI, not Monopoly money. I bridge business goals and technical solutions across the entire lifecycle - from complex, resilient web and mobile platforms to the scalable infrastructure that powers them.
The story so far
I started in 2005, when the web was still figuring itself out. Twenty years later, I'm still building - just at a different scale.
My career has evolved from individual development to leading engineering teams and architecting complex, high-performance systems. I’ve shipped production code across a wide range of domains - including e-commerce, fintech, premium manufacturing, and FMCG - building everything from resilient web platforms to the cloud infrastructure that powers them.
I operate across the full stack, but my focus is rarely just on the code. I see my role as bridging the gap between business objectives and technical execution. I am a firm believer that code should drive ROI, not just burn through budgets - because at the end of the day, we aren't playing with Monopoly money. Whether I’m designing a system’s architecture or optimizing a deployment pipeline, I ensure that every technical decision serves a clear, results-driven purpose.
Today, I am focused on the next phase of efficiency: integrating AI-powered workflows, RAG pipelines, and automated intelligence to build smarter software and more effective teams.

Selected projects
Full-Stack Web Application
Architected and led development of an enterprise-scale arts & ticketing platform - serving over 1M orders, 100k+ users, and 2,000+ annual events with traffic spikes during high-demand releases. Owned the full AWS infrastructure, integrated OpenAI LLMs to enhance customer experience, and integrated a third-party ticketing platform via real-time webhooks for a seamless purchase flow. Built on Laravel with a React + TypeScript frontend using Inertia.js and SSR for SEO, Redis for caching and sessions, and a queue-based background job system. Delivered automated CI/CD via Bitbucket pipelines, queue workers, and Sentry for error tracking and performance monitoring.
Custom E-commerce Platform
Architected and led development of a fully bespoke e-commerce platform - designed the data model and system boundaries from scratch to handle complex product configurator logic, manufacturing-aware inventory, and multi-currency pricing. Owned Streamsoft Prestiż ERP integration for real-time stock synchronisation, search infrastructure via Algolia, and payment processing. Introduced Redis for caching heavily-computed configurator pricing and inventory data, significantly reducing database load. Coordinated a cross-functional frontend team and delivered automated customer segmentation, multilingual support, and a CI/CD pipeline.
Shopify Payment Applications
Developed official Shopify payment gateway applications for three financial institutions - Poland's leading BNPL platform, one of Poland's leading banks, and a UK-based BNPL platform. Implemented the full payment session lifecycle (authorization, capture, void, refund) with strict idempotency guarantees and asynchronous resolution flows. Security-first implementation covering mTLS for bidirectional channel encryption, HMAC request verification, and end-to-end data encryption to meet PCI requirements. Managed the complete OAuth flow, webhook lifecycle, and compliance webhooks. Built with Node.js and Remix, Polaris on the frontend for a native Shopify admin experience.
Mobile App & Partner API
Designed and delivered the companion mobile app to a large-scale cultural events platform - built with an AI-first, spec-driven development workflow from architecture through release. Engineered the codebase to be AI-ready from the ground up: strict linting, testable architecture, and spec-driven guardrails enabling AI agents to contribute reliably across the entire codebase. Cross-platform React Native app on Expo with SSO via Google, Facebook, and Apple, Redux Toolkit for state management, and Uniwind for styling. The REST API was architected for multi-consumer use - serving the mobile app alongside multiple third-party partner integrations at the same scale as the web platform.
Enterprise Website
Built a headless enterprise web platform for one of Poland's largest FMCG brands - architected with Next.js using a hybrid SSG/ISR strategy to balance performance and content freshness across three regional markets. Extended Strapi with custom plugins to meet complex content modelling requirements, and implemented role-based editorial access for independent market teams. Deployed on Azure infrastructure defined in Bicep, with CI/CD pipelines via Azure DevOps.
