Param Aggarwal is an engineering leader and early-stage builder with 12 years of experience delivering mobile-first products and scaling teams across startups and large product companies. He has driven platform migrations—most recently leading Groww’s Mutual Funds move to React Native—and repeatedly improved user conversion and reliability through pragmatic product-focused engineering (e.g., a 3x conversion lift by switching import tracking from email to phone). Param combines hands-on mobile development (including notable contributions to the upstream React Native repo) with strong operational practices like RCA reviews and synchronized release demos to meet tight compliance deadlines. At cure.fit he grew Cult Live from 1K to 80K paying customers, rebuilt critical streaming and ML debugging infrastructure, and led cross-team Flutter migrations for hardware-connected companion apps. As a founding engineer at Craftworks he shipped three distinct products spanning real-time video, recruitment tooling, and no-code video personalization, demonstrating both product sense and systems design. Based in Bengaluru, he blends startup grit with enterprise discipline, often surfacing engineering fixes that materially impact business metrics.
