Performance Audit & Fix for Slow Web Apps and APIs
A measured look at why your web app or API is slow, followed by fixes for the biggest causes. For small teams on Laravel, Go, Python or Vue/Nuxt with MySQL, MariaDB or Postgres. Audit from $650 ($500 founding), audit plus fixes from $1,300. Typical timeline 1–3 weeks. Email the slow pages and your stack.

Who this is for.
A good fit if
- SaaS founders whose pages or API calls got slower as data grew
- Small teams who see timeouts, queue backlogs or a database at 100% CPU
- Agencies with a client app that “feels slow” and no one to profile it
Common triggers
- A customer complaint or churn reason that says “slow”
- The database server bill went up because the instance was sized up to hide the problem
- Background jobs finish hours late
- A growth spike is coming (launch, campaign, seasonal peak)
Not a fit if
- It’s a WordPress site (I handle WordPress speed work elsewhere, not here)
- You need a guaranteed score or response time before any measurement
- The app is down right now (book an Urgent Fix instead)
What I do, and what you get.
What I do
- Agree on 3–5 measurable targets with you first (for example, “the orders page under 1 second at the 95th percentile”)
- Measure a baseline on production or a copy of it: slow-query log, query counts per request, response times, server load
- Trace the slowest paths to their causes: N+1 queries, missing indexes, heavy serialization, uncached work, sync work that belongs in a queue, oversized assets
- Write a ranked findings list with the effort for each fix
- On fix tiers, apply the agreed fixes as reviewed changes, with tests where the code path allows
- Measure again with the same method, so before and after are comparable
What you get
- Baseline and after-measurements, side by side, using the same method
- Ranked findings list with effort estimates
- Code changes as a pull request (fix tiers), plus any index migrations
- Server configuration changes written down (PHP-FPM, OPcache, database settings, caching)
- Handover notes: what changed, how to re-run the measurements, what to watch
Your part
- Repository access and a staging copy, or permission to measure production read-only
- A person who can approve changes and a deploy slot
- Names of the pages, endpoints or jobs that matter most to your business
Included
- Back end, database and server-side caching
- Front-end asset and bundle size checks
- Up to 5 agreed targets per engagement
- One re-measurement after fixes
- Index and query changes with migration
Not included
- WordPress speed work
- Redesigning pages or rewriting the front end
- Guaranteed scores or response times
- Ongoing monitoring (see Care Plans)
- Moving to new hosting or new servers (see Split to Multi-node)
Fixed prices, agreed before work starts.
Baseline, causes, ranked fix list with estimates
Audit plus fixes for the top findings, re-measured
Audit + Fix for a larger app or several services, plus caching layer or queue changes. In 2 monthly milestones of $975 ($750 founding).

Founding price: 3 of 7 spots left, until Mar 31, 2027 — one-off work, in return for a testimonial. How it works
Prices are in USD, paid by bank transfer against an invoice. Work under $1,000 is paid upfront; larger work is 50% to start and 50% before handover, or monthly milestones. How working together works
Variations
- Laravel/PHP
- Debugbar or Telescope on staging, query log, OPcache and PHP-FPM tuning.
- Go or Python APIs
- Built-in profilers (pprof, py-spy), connection pools, worker counts.
- Vue/Nuxt front ends
- Bundle analysis, lazy loading, server rendering and caching headers.
- Queue-heavy apps
- Job timing, batching and worker sizing instead of page speed.
How it runs.
- 01
Send the slow pages
You email the slow pages, stack and hosting, and I confirm fit within 1 US business day.
- 02
Agree targets
We agree on targets in writing and you pay the invoice.
- 03
Measure and find causes
I measure, trace the causes and send you the ranked list.
- 04
Apply fixes
On fix tiers, I apply the fixes on staging, you review, and we deploy in an agreed window.
- 05
Re-measure and hand over
I re-measure with the same method and hand over the notes.

35 Prometheus metrics built into a production Go service, so slow paths are measured, not guessed.

Tuned nginx, PHP-FPM, MariaDB and Redis stacks installed on servers across five clouds.
Read the case study →Questions buyers ask.
Can you promise my app will be X times faster?
No. I promise measured targets agreed up front, and I show before-and-after numbers from the same method.
Will you need production access?
Read access to logs and the database’s slow-query data helps a lot. Changes go through staging first.
What if the real fix is bigger hardware or a split database?
I’ll say so in the report with the reasons, and quote it separately (Scale-up: Split to Multi-node).
Do you fix the front end too?
Asset size, caching and lazy loading, yes. A redesign, no.
What if the fix list is longer than the tier?
You get the full ranked list. I fix the top items in scope and quote the rest.
Ask about Performance Audit & Fix.
Tell me what you have and where it hurts. I reply within one US business day with either a fixed quote or the entry step that makes a fixed quote possible.
Helpful to include
- Stack and versions
- Hosting (provider, server size)
- The 3–5 slowest pages, endpoints or jobs
- How slow they are now and what “fast enough” means to you
- Monthly users or requests
- Is there a staging copy?
- Deadline or trigger

Cloud Cost Review
A fixed-price, read-only review of your cloud bill for small teams on AWS, Google Cloud, Azure or DigitalOcean-style hosts. You get an itemized map of what you pay for, what looks oversized or unused, and what changing each item would involve. From $390 ($300 founding), about one week. Email your provider and monthly spend.
Scale-up: Split to Multi-node
For apps that have outgrown one server: I move the database to its own server, or add a load balancer and a second app server, with a planned maintenance window and a written rollback plan. For Laravel, Go, Python and Node apps on VPS or cloud servers. From $1,300 ($1,000 founding), about 2–3 weeks.
