What I'm looking for

I'm open to senior or lead frontend roles, ideally remote 6- to 24-month engagements with EU or US teams building SaaS and AI-powered products.

I build and scale SaaS and AI-powered products with React, Next.js, and TypeScript. At Watad, I develop a multi-role SaaS platform supporting 10k+ active users per month.

I improved Watad's frontend performance by about 30% and achieved under-two-second First Contentful Paint on key pages. I also implemented secure authentication and RBAC, eliminating unauthorized-access incidents.

At LSK Software Consulting and Pyra.AI, I led frontend delivery for AI workflows, including speech-to-text and text-to-speech features that increased engagement by 40%. I built reusable UI systems, real-time data experiences, and testing pipelines while collaborating closely with design, backend, and product teams.

I've also built HumanizeIt solo as a full-stack SaaS using the Claude API and Stripe, alongside projects including LinkedOut and BundleViz. I'm remote-first and focused on practical architecture, fast delivery, and product experiences that scale reliably.
