Need a bug fixing service that actually solves the problem, not just patches symptoms?

I offer professional debugging and performance optimization for businesses whose site is slow, broken, or unreliable. As an experienced troubleshooting expert, I diagnose issues across frontend, backend, database, and server layers, then deliver speed optimization that measurably improves load time and stability.


What you get:


  • Root-cause bug fixing across frontend, backend, and database
  • Full performance audit (load time, queries, assets)
  • Speed optimization: caching, lazy loading, query tuning
  • Before/after performance report
  • Cross-browser and cross-device testing


If you're searching for someone to fix bugs, debug a broken feature, or optimize performance for better conversions and SEO ranking, this gig covers it. I work fast, document everything I find, and deliver fixes you can trust in production ideal for businesses that need a dependable bug fixing and performance optimization expert on demand.

👋 I'm Mike, CEO and Founder of LeaSoft, a full stack team specializing in SaaS development and AI-accelerated builds. I've solved what keeps founders up at night: billing logic that breaks, user roles that don't scale, MVPs that never ship. My team builds subscription billing, authentication, and admin dashboards that hold up once real users show up, and we've cut development timelines by 24% without cutting corners. When you work with me, you get someone who treats your product like it's mine, moves fast, communicates clearly, and ships SaaS platforms that are actually ready to launch.
