I Dig You Out of These Holes
SaaS CTOs Drowning in Technical Debt
Your React app loads like it's 2015. Users bounce before seeing content. I clean legacy spaghetti code and implement modern architecture that scales.
Designers Whose Prototypes Get Butchered
Your beautiful Figma designs become frankenstein frontends. I bridge design-dev gap with pixel-perfect components and smooth animations.
Startups Racing to Fix Slow Signups
Page speed kills conversions. Every 100ms costs revenue. I optimize Core Web Vitals and implement performance monitoring that actually works.
