About

I'm a solo developer who enjoys turning ideas into real products. I build and launch mobile apps, web tools, AI-powered workflows, and digital experiments across different problems. My projects include Precivo, Cancelo, Healthy Chew, and several other independent products and prototypes. I work end to end—from product strategy, UX, and design to engineering, analytics, monetization, localization, automation, and app store releases. I like learning by shipping, testing ideas with real users, and turning complex problems into simple and useful experiences. I'm always open to meeting other makers, founders, collaborators, and strategic investors.

Precivo - Pricing and profit calculator for makers and small sellers

Precivo is a free mobile app that helps makers, artisans, and small sellers calculate what to charge without selling at a loss. Add materials, labor, packaging, production costs, marketplace fees, discounts, and desired margin to see your real cost, recommended price, profit, and margin. Unlike generic spreadsheets, Precivo is mobile-first, easy to use, and built for handmade, 3D-printed, and small-batch products—including product kits.
