Website & App Performance Optimization
Speed isn't a feeling you promise - it's a number you measure before and after. I profile component mounts and Core Web Vitals, fix what the data says is actually slow, and hand you the exact result, not an adjective.
Why Work With Me
I bring more than code to the table. Here is what makes working with me different from typical agencies.
Lightning Fast Delivery
I use modern frameworks and proven workflows to deliver projects 40% faster than traditional agencies without compromising quality.
Battle-Tested Code
Every line of code is written with TypeScript, follows best practices, and includes automated tests for reliability.
Always Responsive
Direct communication with me - no account managers, no delays. Get answers within hours, not days.
Long-term Partnership
I don't disappear after launch. I stay for maintenance, updates, and continuous improvements of your product.
Performance Measured, Not Marketed
Every optimization here starts with a number and ends with a re-measured number - the same profiling discipline used to cut this site's own case-study page mounts by over 80%.
Fixes Diagnosed at the Render Level
Slow pages are diagnosed at the component-mount and render level, not guessed at from a single Lighthouse score - the same technique that found and fixed this site's own performance bottlenecks.
What's Included in Performance Optimization
Component-Mount & Render Profiling
The actual diagnostic technique behind every fix: tracing how many components mount and re-render on cold navigation via Chrome DevTools' Performance panel - not a generic "we check speed" claim.
Core Web Vitals Audit
A full audit of all five Core Web Vitals metrics - LCP, INP, CLS, TTFB, and FCP - benchmarked against Google's thresholds and your real traffic conditions.
Code-Splitting & Lazy-Loading Review
Every bundle is reviewed for code that ships to visitors who never use it, and split or lazy-loaded so the initial payload only carries what the current view needs.
Caching-Strategy Audit
A Cache Components/PPR-aware review of what's statically cached, what's dynamic, and where the boundary between them is costing you render time.
Before/After Measurement Reporting
Every engagement closes with a documented before/after report - not an estimate, the actual re-measured numbers against the locked baseline.
Proven on This Site's Own Case-Study Template
This exact methodology cut production cold-navigation component mounts from 3,747 to 738 (-80.3%) on the shared case-study page template used by every project on this site - a sitewide fix, not bespoke engineering for one client.

Transparent Process
No black boxes. You know exactly what is happening at every stage.
Performance Audit & Profiling
I profile the site with Lighthouse and Chrome DevTools' Performance panel, and trace real component-mount and render counts on cold navigation - not just a single Lighthouse score screenshot. Every slow path gets a number attached to it.
Findings & Prioritized Roadmap
The audit's findings become a roadmap ordered by measured impact: the fixes that move the numbers most ship first, not the ones that are easiest to talk about.
Implementation
I implement the fixes directly: code-splitting and lazy-loading, caching-layer adoption (Next.js Cache Components / PPR where applicable), and render-path fixes that remove unnecessary component mounts and re-renders.
Re-Measurement & Reporting
The exact same profiling pass runs again against the locked baseline, and you get the before/after numbers - delivered, not assumed. If a fix didn't move the number, that gets reported too.
