Browser Cache Blocking App Updates
Users don't see app updates. Old JavaScript cached in browser. New features don't appear even after deployment. Cache headers prevent fresh content.
Browser caches static assets for performance. Without proper cache headers, users see stale code.
Common Causes
- Cache-Control header allows long expiry
- File hashes not changing between builds
- Browser cache not cleared on new deployment
- CDN caching old assets
- Service worker caching old files
How to Fix It
Configure cache headers in server:
// Cache busting with file hashes in Vite (default)
// main.abc123.js - changes on build
// HTML should not cache
Cache-Control: no-cache, must-revalidate
// JS/CSS can cache long
Cache-Control: public, max-age=31536000, immutableOr add version query: ?v=1.0.0 to force reload.

Full-stack developer experienced in fixing and deploying AI-generated apps from Lovable, Bolt.new, Cursor, and Replit. I specialize in debugging Supabase integration issues (auth flows, RLS policies, database connections), fixing broken deployments, resolving routing/blank screen problems, and cleaning up messy React/Vite codebases. I also build production apps with the Claude API and have shipped a Mac desktop dev tool (Nexterm from scratch. Based in Hong Kong, fast turnaround.

Basel Issmail
’m a Senior Full-Stack Developer and Tech Lead with experience designing and building scalable web platforms. I work across the full development lifecycle, from translating business requirements into technical architecture to delivering reliable production systems.
My work focuses on modern web technologies, including TypeScript, Angular, Node.js, and cloud-based architectures. I enjoy solving complex technical problems and helping teams turn product ideas and prototypes into working platforms that can grow and scale.
In addition to development, I often collaborate closely with product managers, business analysts, designers, and QA teams to ensure that solutions align with both technical and business goals.
I enjoy working with startups and product teams where I can contribute both as a hands-on engineer and as a technical partner in designing and delivering impactful software.

I’ve watched the tech landscape evolve over the last decade—from the structured days of Java Server Pages to the current "wild west" of Agentic-driven development. While AI can "vibe" a frontend into existence, I specialize in the architecture that keeps it from collapsing.
My expertise lies in the critical backend infrastructure: the parts that must be fast, secure, and scalable. I thrive on high-pressure environments, such as when I had only three weeks to architect and launch an Ethereum redemption system with minimal prior crypto knowledge, turning it into a major revenue stream.
What I bring to your project:
Forensic Debugging: I don't just "patch" bugs; I use tools like Datadog and Explain Analyzers to map out bottlenecks and resolve root causes—like significantly reducing memory usage by optimizing complex DB joins.
Full-Stack Context: Deep experience in Node.js and React, ensuring backends play perfectly with mobile and web teams.
Sanity in the Age of AI: I bridge the gap between "best practices" and modern speed, ensuring your project isn't just built fast, but built to last.

Get HelpFrequently Asked Questions
How does Vite handle cache busting?
Automatically adds content hash to filenames. main.abc123.js changes when content changes, forcing new download.
What if users still see old version?
Hard refresh (Shift+F5) clears browser cache. Serve index.html with no-cache header.
