Fast, Secure, and Ready for Real Traffic
Performance and security aren't things you bolt on at the end — but they often end up that way. If your application is slow or has security gaps, I fix them properly rather than applying patches that don't address the root cause.
Frontend Performance
I optimise for Core Web Vitals — LCP, CLS, and INP — which affect both user experience and SEO rankings. This means looking at image optimisation, JavaScript bundle size, render-blocking resources, font loading, and server response times. I measure before and after so you can see exactly what improved.
Backend Performance
Slow backends are usually slow for one of a small number of reasons: inefficient database queries, missing indexes, N+1 query problems, lack of caching, or simply doing too much work per request. I profile and fix each of these systematically.
Database Optimisation
Poorly designed queries can turn a fast application into a slow one overnight as data grows. I review query patterns, add appropriate indexes, optimise schema design, and set up proper connection pooling.
Security Hardening
I go through authentication and session management, access controls, input validation, secrets management, HTTP security headers, dependency vulnerabilities, and infrastructure security. Each finding gets a specific remediation, not just a flag.
