Lead Full-Stack Web & Mobile Developer & Fractional CTO who builds scalable platforms and the engineering teams behind them. Author of _React - The Road To Enterprise_ and _Vue - The Road To Enterprise_. Speaker at React Summit, React Advanced London, and Vue Amsterdam. Currently serving as CTO in the energy sector, where I consolidated three separate codebases into a single multi-tenant white-label platform - designing the full architecture from tenant-isolated data and custom domain routing to a granular RBAC permissions system built from scratch. I personally conduct penetration testing, and identified and fixed SQL injection and path traversal vulnerabilities in production. I resolved a critical performance bottleneck where PDF generation blocked the entire server for 60+ seconds, and built Playwright e2e test suites that automated quarterly financial verification - replacing hours of manual QA. I build the full stack - React, React Native, Next.js, Vue, Node.js, TypeScript, PostgreSQL, MySQL, Docker, AWS - but what I bring beyond the stack is the ability to make hard architectural calls and follow through on them in production. I've established engineering functions from scratch, hired and mentored teams, and led the structured adoption of AI-augmented development workflows with defined standards and guardrails. ### Credentials I'm the author of "React - The Road To Enterprise" and "Vue - The Road To Enterprise," covering advanced patterns, scalability, and best practices for building production-grade applications ([https://theroadtoenterprise.com](https://theroadtoenterprise.com/)) I've spoken at and led workshops at major international conferences including: * React Summit — Composition vs Configuration: How to Build Flexible, Resilient and Future-proof Components ([https://portal.gitnation.org/contents/composition-vs-configuration-how-to-build-flexible-resilient-and-future-proof-components](https://portal.gitnation.org/contents/composition-vs-configuration-how-to-build-flexible-resilient-and-future-proof-components)) * React Advanced London — Advanced Patterns for API Management in Large-Scale React Applications ([https://portal.gitnation.org/contents/advanced-patterns-for-api-management-in-large-scale-react-applications](https://portal.gitnation.org/contents/advanced-patterns-for-api-management-in-large-scale-react-applications)) * Vue Amsterdam — Vue Experts Panel & The Case Study of Findlay Web Tech ([https://www.youtube.com/live/El8Jw2CFj7g?si=EUVzHQgAbtPNUAwq&t=5507](https://www.youtube.com/live/El8Jw2CFj7g?si=EUVzHQgAbtPNUAwq&t=5507)) * React Wednesdays — Best Practices for Testing React Apps ([https://www.telerik.com/react-wednesdays/react-wednesdays-best-practices-for-testing-react-apps](https://www.telerik.com/react-wednesdays/react-wednesdays-best-practices-for-testing-react-apps)) * GDG React Workshop — How to Handle APIs in React Applications ### Technical Stack Frontend: React, Next.js, Vue, Nuxt, React Native, TypeScript Backend: Node.js, Express, Fastify, Python, PHP Databases: MySQL, PostgreSQL, Firebase Infrastructure: AWS Lambda, BullMQ, VPS, Docker, GitHub Actions, Datadog Testing: Playwright, Vitest, E2E & API test automation Security: Penetration testing, RBAC design, SQL injection & path traversal remediation AI Tooling: Cursor, Claude Code, AI-augmented development workflows ### Who I Work With Open to remote full-time & part-time contract roles in senior full-stack engineering, technical architecture, tech lead, or fractional CTO engagements.
