What I'm looking for

Data and user feedback-based decision-making. Complex, data-heavy platforms. Artificial Intelligence. Ownership. Responsibilities.

"Big Data is the oil of the future," said Sujeevan Ratnasingham, Director of Informatics at the Centre for Biodiversity Genomics - one of many visionary leaders I've had the privilege to collaborate with. This perspective captures my focus: using AI and Big Data to drive innovation for startups across HealthTech, EdTech, and emerging technologies, transforming complex challenges into measurable outcomes that impact real lives.
Through this approach, I've supported systemic transformation affecting 235,580+ students across US school systems, achieved 60% sales growth by pioneering revolutionary Content Nesting methodology, and designed AI systems processing 2.4M+ daily articles for enterprise threat detection. These results stem from combining strategic thinking with rapid execution - like delivering a fully documented AI-driven AR physiotherapy prototype in 49 hours.

Selected from 100,000+ global applicants for Toptal's elite network during its premium era (2019), I now serve as a lead designer for AI startups, specializing in 0-to-MVP development and constraint-driven innovation.

Collaborating with teams across North America and EMEA, I've mastered async work and proactive ownership. By leveraging time zone differences, I rapidly prototype, iterate, and deliver solutions - often moving projects forward while others are offline. This approach consistently accelerates feedback cycles and drives efficient outcomes for global startup teams.

My creative roots run deep in classical art, which shaped my eye for detail, composition, and visual harmony. This artistic foundation continues to influence my approach to digital product design, helping me blend aesthetics with functionality while solving complex technical challenges. I redesign backbone functionality rather than just interfaces, introducing async collaboration methodologies to teams and applying philosophical principles to transform navigation complexity.

Experienced across multiple sectors, including healthcare systems design, I've successfully redesigned core scheduling functionality for ABA therapy platforms, created decision tree systems for neurological assessment, and developed AI-driven physiotherapy measurement tools. Whether working with US federal agencies under strict compliance requirements or scaling retail platforms across 25+ countries, I translate ambitious AI visions into focused, collaborative missions.

Ready to transform your AI startup's complex challenges into user-centric solutions? Let's connect to explore how constraint-driven design can accelerate your 0-to-MVP journey.
