What I'm looking for

I'm looking for a senior mobile, full-stack, or AI-focused role.

At Rechaj, I own six production Flutter apps across field surveys, sales, battery swaps, retrofits, logistics, and factory assembly. I also manage store releases and build across the Spring Boot API and operations console.

I built Rechaj Trek end to end, connecting a Spring Boot service, React dashboard, and Flutter capture app so photo review and contractor payouts work in one system. I also designed Rechaj’s image processing service, using Claude, OpenAI, and Gemini to extract vehicle plates from photos.

At GearSparks, I built the Book Rion reading app and WorkSage’s AI assistant mobile app from the ground up. Earlier, I built Yum at CredPal and contributed to the CredPal consumer credit app; I’m looking for a senior mobile, full-stack, or AI-focused role.
