About
Professional summaryI am an engineering leader and hands-on mobile developer with 10 years of experience shipping React Native products from zero to paying users.
I have built and led small teams across three startups, owned end-to-end mobile delivery, and worked closely with product and design to turn ideas into production-ready apps.
My experience includes leading a Techstars top-10 product selected from around 1,500 applicants, as well as shipping a new workout module into a live fitness app serving about 6,000 paid subscribers within two months.
I have deep practical experience across the full mobile stack, including React Native, TypeScript, iOS, Android, Firebase, REST APIs, payments, analytics, release automation, and CI/CD.
I also founded and ran a small IT outsourcing agency, where I handled sales, hiring, client delivery, pricing, and team leadership while building mobile apps for clients.
I enjoy taking ownership of architecture, performance, delivery, and team growth, and I am comfortable working in fast-moving product environments where execution matters.
I am open to opportunities where I can combine technical depth with leadership, help teams ship reliably, and contribute to product growth.
