Description

I am aSenior Flutter Engineer & Tech**Lead** with over 5 years of experience building digital products that combinesolid architecture, extreme performance, and memorable user experiences.I have led the complete cycle of10+ cross-platform applications (iOS, Android, Web, Smart TV)deployed in 11 countries, always with a focus onreal business impact.

At Yuvod,I led the technical strategy for an OTT platform for hotels, deployed in 30+ establishments in Europe and LATAM. I designed scalable architectures and solved a key challenge: creating aspatial navigation system for Smart TVsthat reduced usage errors by 70% and increased guest satisfaction. Additionally, I optimized performance on low-end TVs, reducing startup time from 30 to 6 seconds and decreasing the onboarding abandonment rate by 45%. Result: a more profitable product with better retention.

At Optimus Apps Lab,I delivered 5+ B2B apps in neobanking, logistics, and tourism. I implementedbiometric authenticationthat reduced login friction by 60% andreal-time geolocationthat improved logistics efficiency by 30%. Thanks to standardized architectures and reusable components, I reduced time-to-market by 35%, accelerating MVP validation and customer ROI.

My13-year background in tech retailgives me a differential advantage: I know how to translate technical complexity into tangible benefits for non-technical audiences. I have trained teams, guided stakeholders, and closed deals by explaining technology in business language.

Today, I bring aunique blend:technical leadership, product vision, and empathy for the end-user. My mission is clear: **turn ideas into scalable, measurable, and customer-centric products**, where every technical decision translates into business value.
