Building faster apps for real people

We started Quill Foundry Marigold in 2019 after seeing too many businesses struggle with apps that felt sluggish. Our small team in Lucknow focuses on mobile app performance because we believe every user deserves smooth experiences, regardless of their device or network connection.

How we got here

Back in 2018, I was helping a friend with his e-commerce app. Great product, solid design, but the app took forever to load. Customers were leaving before they even saw what he was selling. That's when it clicked — performance isn't just a technical metric. It directly affects whether someone stays or leaves.

We started small, just three of us in a shared office space. Our first project was a food delivery app that crashed during peak hours. Spent weeks profiling every function, analyzing memory usage patterns, rewriting database queries. When we got it stable, the client saw their order completion rate jump significantly within two weeks.

That early success taught us something important: most businesses don't need fancy features. They need apps that work reliably when users actually need them.

Now we work with startups and established companies across India. Some need help with React Native optimization. Others are dealing with Flutter performance issues. Each project is different, but the goal stays the same — make apps feel responsive and reliable.

Our practical approach

We don't follow rigid methodologies or use buzzwords. Every app has unique bottlenecks, and we adapt our process based on what we find during analysis.

Start with measurement

Before changing anything, we measure current performance across different devices and network conditions. This gives us a realistic baseline and helps identify the actual problems rather than guessing.

  • Profile app behavior on budget Android devices commonly used in India
  • Test under 3G and unstable network conditions
  • Analyze memory consumption patterns during typical usage
  • Document loading times for critical user flows

Fix what matters first

Not all optimizations deliver equal impact. We prioritize changes that users will actually notice — faster app launches, smoother scrolling, quicker image loading. The technical debt that doesn't affect user experience can wait.

  • Target bottlenecks in frequently used features
  • Address issues visible during first-time user experience
  • Reduce bundle sizes for faster downloads
  • Improve caching strategies for offline functionality

Test with real scenarios

Lab tests only tell part of the story. We test changes under conditions your actual users face — older phones, congested networks, background apps competing for resources. This reveals problems that synthetic benchmarks miss.

  • Run tests on devices representing your user base
  • Simulate real-world network variability
  • Monitor crash reports after each optimization
  • Track user session data to verify improvements

Document everything clearly

Your team needs to maintain these changes long after we're done. We provide clear documentation explaining what we changed and why, plus guidelines for keeping performance stable as you add new features.

  • Create performance budgets for future development
  • Set up monitoring alerts for regression detection
  • Provide code review checklists focused on performance
  • Train your team on common optimization techniques
