About this gig
PLEASE CONTACT ME BEFORE PLACING AN ORDER. Lets briefly discuss your tech stack in the inbox first to ensure we choose the perfect package for your needs!
Is a sluggish web app hurting your user retention, SEO, and conversions?
When an app slows down, most developers just throw expensive cloud resources at it. As a Senior Full-Stack Engineer with over 14 years of experience, I dont patch symptomsI cure the root architectural bottlenecks.
In my corporate career, I spearheaded an architectural redesign that successfully reduced a critical application's initial load time from 15 seconds down to just 2 seconds. I bring this exact level of elite engineering maturity to your project.
What I Optimize:
- Frontend: Bundle splitting, lazy loading, and asset tuning in React, Angular, and TS/JS.
- Backend: Eliminating bottlenecks in Node.js, Python, and C# web services.
- Databases: Indexing, query restructuring, and schema tuning for PostgreSQL, MongoDB, and SQL.
- Cloud: Optimizing AWS, Azure, and Vercel environments to slash response times and hosting costs.
Let's make your app lightning-fast!

Do you guarantee a specific speed increase (like under 2 seconds)?
While every application is unique, I guarantee a measurable, significant reduction in latency. I use professional benchmarking tools before and after my work so you can see the exact performance ROI.
What do you need to get started?
For the Audit, just a summary of your tech stack and the specific performance issues you're facing. For hands-on optimization, I will require secure, temporary access to your repository (GitHub/GitLab) and database/hosting environment configuration.
