David Riley

I'm a Senior Software Engineer with 14+ years building scalable, interactive web applications. I focus on TypeScript, React, Node.js and modernizing legacy codebases to improve user experience and developer velocity.

At Sonar Labs and other clients I delivered full‑stack marketplace solutions for Web3, enabling multi‑vendor token trading with real‑time portfolio management and analytics dashboards. I built secure authentication systems supporting multiple identity providers and role‑based access control and defined API architectures for resilient integrations. I also optimized platform performance and responsiveness through data presentation, error resilience, and front‑end improvements.

I led front‑end architecture and migrations — notably moving codebases to TypeScript and Tailwind CSS, cutting maintenance by 25% and reducing bundle sizes. I consolidated UI frameworks into shared components and drove accessibility upgrades to meet WCAG 2.0 across learner platforms. I mentor teams on engineering practices, testing, and developer tooling.

I founded a consulting firm to help early‑stage startups with web applications, API design, and front‑end architecture, turning engagements into long‑term partnerships. I'm drawn to roles where I can modernize systems, lead technical direction, and deliver measurable impact.
