Application Performance Optimization
Your application is big. Your users should not have to feel it.

Where I can help
I investigate slow user journeys in existing web applications, connect the symptoms to measurable bottlenecks and implement targeted improvements. The starting point is what users experience, from loading and interaction delays to expensive requests and unreliable flows.
- Baseline the slow journeys on representative devices and workloads.
- Profile rendering, bundles, network waterfalls and API interactions.
- Investigate bottlenecks across the relevant application and integration boundaries.
- Validate selected fixes against the same baseline and add regression visibility.
What you get
- A performance baseline and reproducible bottleneck report.
- A ranked improvement plan based on user impact.
- Implemented optimizations for the agreed flows.
- Before-and-after measurements and guidance for preventing regressions.
How we work
We agree on the problem, access, decision owners and acceptance criteria first. I review the current context, propose a focused scope and work with your team through the agreed deliverables. Progress, open risks and the next owner are documented throughout.
Identified bottlenecks and delivered changes that improved the speed and user experience of a client web application, alongside production troubleshooting and observability work.
Before we start
What engagement format works best?
Focused performance assessment + implementation sprint. We confirm scope, availability and responsibilities before starting.
What will we use to assess progress?
A performance baseline and reproducible bottleneck report. A ranked improvement plan based on user impact. Implemented optimizations for the agreed flows. Before-and-after measurements and guidance for preventing regressions.
What are the boundaries?
Specific speed gains depend on the baseline, codebase and workload. No percentage improvement is promised before measurement.
What do you need to get started?
An overview of your product, current challenges, relevant documentation and the people responsible for decisions. Repository or system access is agreed only where needed.
