You will get Ruby on Rails Performance Audit
Top Rated
Project details
Is your Rails application leaving money on the table? A slow-loading site kills conversions and damages your brand. Every one-second delay can decrease sales by up to 7%. This audit is designed to find and fix the hidden performance bottlenecks in your Ruby on Rails application, directly boosting your bottom line.
What sets our audit apart is our specialization. We are not generalists; we are a team of over 45 senior Ruby on Rails experts who live and breathe high-performance e-commerce/applications. We leverage years of experience scaling high-traffic online stores to provide insights that automated tools simply cannot find. We dig deep into your code, database, and infrastructure.
We deliver more than just a report; we provide a prioritized, actionable roadmap to a faster, more reliable store. You’ll get a clear plan to improve user experience, increase conversions, and reduce server costs.
Stop guessing what’s slowing you down. Let’s get you the data and the solutions you need to grow.

Job Success
Ho Chi Minh City, Vietnam - 1:45 pm local time
My background is hands-on engineering, not slideware. I came up building high-traffic Ruby on Rails systems and complex web applications, and I still stay close to the architecture, the hard technical calls, and the code that has to hold up in production. Over 12+ years I've grown that into a team that does it at scale: 90+ people co-located in one Ho Chi Minh City office, including 75+ engineers (60+ web, 15+ mobile) plus QA, BAs, PMs, and designers.
So when you work with me, you get an engineer who understands your problem at the technical level, and a full team to deliver it.
WHERE I GO DEEP
- Ruby on Rails: high-traffic systems, complex domains, API design, and legacy codebases most people won't touch
- Frontend: React, Next.js, Vue.js, TypeScript, building interfaces that stay fast and maintainable as they grow
- Cloud & DevOps: AWS, Google Cloud, Heroku, Docker, CI/CD, monitoring, and tuning systems for cost and scale
- eCommerce: Shopify, Saleor, Spree, custom headless builds, complex integrations, and migrations off legacy platforms like Magento
WHAT MY TEAM COVERS
Everything above, at scale, plus the full stack around it:
- Backend beyond Rails: Node.js, PHP (Laravel, Symfony), Python (Django, Flask), REST and GraphQL APIs
- Mobile: native (Swift, Kotlin) and cross-platform (React Native, Flutter), including the hard stuff like offline-first sync, BLE sensor processing, and frame-accurate video
- QA, business analysis, project management, and UI/UX design
THE PROBLEMS I LIKE SOLVING
- Operations platforms: the central system that runs bookings, payments, teams, hardware, and compliance when off-the-shelf tools stop coping. Software modeled on how your business actually works, not the other way around.
- Legacy rescue: inheriting a system nobody wants to touch and making it safe to change again, without a risky rewrite. We've taken an 11-year-old codebase from timeout-or-fail to 3-7 second responses.
- Deep integrations: the ones Zapier can't handle and SaaS avoids. Payments, logistics, identity, hardware, compliance-grade audit trails where failure isn't an option.
- Performance: finding the real bottleneck and fixing it. We've cut infrastructure costs 50% and pulled 95th-percentile response times down to 500ms on live products.
PROOF
- Top Rated Agency on Upwork, 98%+ Job Success Score since 2013, 4.8/5.0 average rating
- $10M+ in project value delivered
- Clients who've stayed 5-10+ years, some since 2014
HOW I WORK
- I think like a technical co-founder, not a contractor. I'll tell you when something is a bad idea before you build it.
- I surface technical debt and scaling bottlenecks before they escalate, not after.
- Clear communication across time zones. We're GMT+7, with strong overlap for AU and workable hours for US/EU.
- Long-term thinking. I build systems that scale, not quick hacks that break six months later.
WAYS TO WORK WITH ME
1. Build a core operations platform: internal tools, SaaS, workflow automation, complex integrations, replacing a stack of fragmented tools with one system
2. A dedicated engineering team: backend, frontend, mobile, and QA as an extension of yours, often for years
3. Product and MVP builds: idea to launch, fast but not fragile
If you want someone who understands the engineering, challenges your assumptions, and can put a real team behind it, let's talk.

Kick-off & Business Goal Alignment
We'll start with a call to understand your key business metrics. Is the goal to increase conversion rates, reduce server costs, or improve user satisfaction? This focus ensures our audit delivers business value.
Deep Code & Database Performance Analysis
Our senior RoR experts will conduct a thorough analysis of your codebase and database query performance. We use a combination of automated tools and deep manual review to identify every significant bottleneck in your application.
