What I'm looking for

I want to lead architecture and technology strategy for AI-enabled products—modernising complex systems, strengthening security and delivery, and mentoring teams to ship reliable, maintainable solutions with fast, high-quality outcomes.

I’m a Senior Software Architect and technology leader with 11+ years of experience building, modernising, and delivering complex web, desktop, mobile, and AI-powered products. I define software architecture, recover troubled projects, and translate business requirements into reliable, maintainable solutions.

I combine hands-on engineering with leadership: TypeScript, React, Node.js, and Electron, plus technical leadership in mentoring, security, DevOps, and AI integration. I’ve rebuilt broken systems, improved state-management and architecture, and introduced structured approaches to security and quality.

In leadership roles (including CTO and Head of Frontend), I lead international engineering teams, run security audits, and deliver AI platforms such as prompt management and document-based workflows. I’m especially motivated by simplifying complex systems, adopting new technologies quickly, and helping teams ship high-quality products in challenging environments.
