Experience brief02

Production work

Since 2016

Core stack

Rails + PostgreSQL

Engagement

Diagnosis, project, or contract

Location

Remote

Merged contributions

Gumroad, Discourse, OpenProject

[Inspect the performance case studies](/case-studies/): bottlenecks, measured results, regression coverage, and upstream pull requests. Choose a focused engagement or a longer contract to fit your team’s needs.

01 / Ways to engage

## Start with the shape *of the problem.*

A specific performance incident, a risky legacy area, and a shortage of delivery capacity need different arrangements. Choose the closest starting point.

Focused optimization

### Performance Optimization Service

Investigate and implement high-impact fixes for one or more production issues such as slow requests, expensive PostgreSQL queries, overloaded background jobs, or memory pressure.

- 80-hour initial engagement at $50 per hour
- Rails and PostgreSQL investigation
- Safe implementation of high-impact fixes
- Before-and-after validation

Scoped project

### Rescue & Modernization

Understand and stabilize a problematic area, plan an incremental upgrade, improve coverage around a change, or replace a risky subsystem without assuming a rewrite.

Embedded support

### Senior Contract Engineering

Defined remote contracts involving product delivery, APIs, integrations, PostgreSQL, background processing, architecture, code review, or technical leadership.

02 / Production evidence

## Outcomes from *real systems.*

Selected work from SaaS products where performance and reliability had practical consequences.

**90%+**

### Dashboard load-time reduction

Reduced an SEO product dashboard from more than two seconds to under 200ms.

**1M+**

### Users served

Worked on page speed, CMS rendering, infrastructure, and integrations for a large SaaS product.

**2016**

### Production work began

Experience across SaaS, education, compliance, cybersecurity, and infrastructure automation.

03 / Working approach

## Understand first. *Change with evidence.*

Mature applications carry business rules, operational constraints, and history. The aim is to improve what matters without creating unnecessary replacement work.

1. 01
   
   ### Investigate
   
   Clarify the symptom, business impact, system context, and evidence already available.
2. 02
   
   ### Prioritize
   
   Separate high-impact work from attractive but unnecessary cleanup, and make trade-offs explicit.
3. 03
   
   ### Improve
   
   Implement the agreed change or leave a practical plan the existing team can execute.

04 / Technical writing

## Inspect how I *reason about Rails.*

These articles show the level of detail behind performance and legacy-system work before you start a conversation.

Starting well

## Bring the symptom and the impact.

A useful first message includes the Rails version, what is going wrong, why it matters, any monitoring information already available, and whether you need diagnosis, implementation, or temporary engineering capacity.

A Rails system that needs experienced attention?

## Show me the problem. *We’ll define the work.*
