Identify and fix performance bottlenecks in production Next.js and React applications
I help engineering teams diagnose why their applications are slow, uncover architectural bottlenecks, and prioritize the changes that have the biggest impact.
Senior Software Engineer with experience leading performance and architecture work across large-scale production web platforms, React/Next.js systems, Node.js services, and cloud infrastructure, including leading teams on critical initiatives.
Who this is for
This service is designed for teams working on production Next.js applications that are becoming slower, more complex, or harder to scale.
I typically help startups, product teams, and engineering organizations that want to improve performance, make better rendering and caching decisions, and reduce technical risk before larger frontend changes.
Common problems
Common problems I help solve
Slow page performance
Pages feel heavier than they should, with poor load times and weak Core Web Vitals.
Unclear rendering strategy
Too much client-side rendering, weak use of Server Components, or uncertainty around SSR, ISR, and streaming.
Large client bundles
Heavy dependencies and shared imports increase JavaScript cost and hurt performance.
Inefficient data fetching
Duplicate requests, waterfalls, missing caching, and slow API dependencies.
Architecture that doesn't scale well
Codebases become harder to maintain, reason about, and optimize over time.
Audit offering
Next.js Performance & Architecture Audit
This is not a generic performance report.
It's a focused, engineering-level review of how your application actually behaves in production — where performance is being lost, which architectural decisions are creating bottlenecks, and what is worth fixing first.
The goal is not to list issues. It's to give your team clear direction on what to change, why it matters, and how to prioritize the work.
The audit covers
- Rendering strategy across SSR, CSR, ISR, and Server Components
- Bundle size and dependency analysis
- API and data-fetching review
- Caching strategy evaluation
- Core Web Vitals and loading behavior
- Architecture and maintainability assessment
- Prioritized recommendations and implementation roadmap
Scope depends on the system and goals. Some engagements focus on a few critical pages and quick wins, while others involve a deeper review of rendering patterns, data flow, and architectural decisions.
Typical audits range between $3k–$5k depending on scope and depth.
What you get
Written audit report
A structured report covering key findings, likely root causes, and the patterns affecting performance in your application.
Prioritized action plan
Recommendations grouped by impact and effort so your team can focus on the changes that are most worth making first.
Architecture guidance
Clear direction on rendering boundaries, data-fetching patterns, caching, and structural decisions that affect performance over time.
Review walkthrough
A walkthrough session to review the findings, answer questions, and discuss practical next steps for implementation.
When teams usually reach out
Common situations where an outside review helps
The application feels slower as the codebase grows. Pages that used to feel fast now take longer to load, and it's not obvious where the bottleneck is.
Rendering behavior has become harder to reason about. There's uncertainty around where to use Server Components, client components, SSR, or caching strategies.
Data fetching is creating performance issues. Waterfalls, duplicate requests, or inefficient APIs are slowing pages down.
The frontend architecture is becoming harder to maintain. As the product grows, changes become riskier and performance improvements become harder to implement.
The team wants a second engineering opinion. Sometimes teams simply want another experienced engineer to review the system before making larger changes.
If any of these situations sound familiar, feel free to reach out.
Why work with me
I'm a Senior Software Engineer with experience leading performance and architecture improvements in production systems across React, Next.js, Node.js, serverless platforms, and cloud infrastructure, and guiding teams through complex technical decisions.
My work has involved performance-sensitive frontend systems, backend APIs, distributed systems, and architecture decisions that affect both user experience and long-term maintainability.
I approach performance as an engineering problem, not just a page-speed score. That means looking at rendering strategy, data flow, caching, API behavior, and the architectural choices that influence performance over time.
My experience includes working on large-scale production systems where performance and reliability directly impact user experience.
How it works
What happens after you reach out
1. You send a short description of the system
Share a bit about the application, the stack, the pages or flows you're most concerned about, and the issues your team is seeing.
2. I review the context and scope the audit
I'll review the context, let you know whether it looks like a good fit, and suggest the most appropriate scope based on the system and goals.
3. We schedule a short call if needed
If helpful, we'll do a short call to clarify the system, priorities, and constraints before the audit begins.
Let's take a look at your application
If you're dealing with slow pages, growing frontend complexity, or performance issues in a Next.js application, feel free to reach out.
Send a short description of the application, the stack, the main pages or flows involved, and the performance or architecture issues your team is seeing. I'll review the details and reply by email with the best next step.
