DB optimization
Evil Martians run an audit and propose a radical performance optimization plan accounting for traffic and database specifics, so you can scale peacefully.
Evil Martians method
First, we measure flamegraphs, allocation tracking, query analysis. Partition, fair prioritization scheme, circuit breakers are some of the tools we reach for often. When Rails is the wrong tool for one hot path, we reach for Go, C, or Rust for that path and leave the rest alone.
Growing faster than your infrastructure?
Social proof
Gusto
Gusto runs payroll, benefits, and HR for more than 500,000 businesses, on one of the largest Rails monoliths anywhere, and crossed $1B in annual revenue in May 2026. Evil Martians worked on the infrastructure behind their background jobs.
In a time of rapid change and acceleration, it was amazing to see Andrey able to step in and create value so quickly.

Whop
Whop serves millions of users and needed off PostgreSQL without a maintenance window. We moved 750GB of production data to PlanetScale with zero downtime, running dual databases through the cutover and reconciling the schema dialects as we went. We also cut their Rails test suite and CI time in half, twice.
More teams we scaled
- bolt.new: our partnership runs since 2021. We built the performance infrastructure that carried it from zero to $40M+ ARR in five months.
- Tines: 100x performance improvements in the target areas of their security automation platform.
- Doximity: Go-powered real-time features inside their Rails app.
- Wallarm: optimized the Go event-processing pipeline behind their high-throughput security data.
- NATS: made their Ruby SDK 3x faster.
- Steel: backend services built inside their TypeScript monorepo.
