Turn Fragile, Slow Software Into Sub-Second Reliability.
Slow dashboards churn B2B users, poor Core Web Vitals crush organic conversions, and recurring outages burn engineering morale. We instrument, profile, and eliminate latency across your frontend, APIs, background jobs, and databases.

Tailored for High-Velocity Startups & Established Operators
Technical bottlenecks look different at a 12-person Seed startup in London or New York than at a profitable 20-year operating business modernizing its core workflows. We structure every engagement around your commercial stage.
US & UK Startups (1–30 Employees)
Post-MVP SaaS and marketplace startups experiencing timeouts, slow dashboards, or production incidents as customer data volume and concurrency grow.
Established UK & US Businesses Making the Tech Shift
Established e-commerce, booking, financial, or internal operational platforms losing revenue and staff productivity to sluggish pages and brittle releases.
4 Signals You Need Immediate CTO Intervention
- Key customer screens take 3–10+ seconds to load as account data grows
- Traffic spikes or batch imports trigger 500 errors, deadlocks, or out-of-memory restarts
- Engineers spend 50%+ of every sprint firefighting regressions instead of shipping roadmap items
- Poor Core Web Vitals (LCP, INP, CLS) are hurting Google rankings and paid acquisition conversion rates
Core Stacks, Cloud & Standards Audited
- PostgreSQL / MySQL Query & Index Tuning
- Next.js / React / Vue / React Native Profiling
- Core Web Vitals (LCP, INP, CLS) Optimization
- OpenTelemetry, Sentry, Datadog & Grafana
- Zero-Downtime CI/CD & Load Testing (k6)
Concrete Deliverables & Timeline
Every engagement produces tangible engineering artifacts, executive clarity, and shipped improvements—never vague slideware.

How GotYourTech Compares to Status Quo Alternatives
Dev agencies profit from longer hours and ground-up rewrites. Unassisted teams accumulate silent risk. Our incentives are 100% aligned with your P&L and valuation.
| Dimension | Without Senior CTO | Typical Agency / Junior Lead | GotYourTech Principal CTO |
|---|---|---|---|
| Troubleshooting Method | Restarting servers and upsizing DB RAM blindly | Patching symptoms without APM flamegraphs or explain plans | Root-cause telemetry across SQL plans, memory, network & bundle |
| Regression Prevention | Manual QA in production by frustrated customers | Ships features fast, leaves brittle test coverage | Automated CI gates, load benchmarks & observability SLOs |
| Business Impact | Enterprise churn & poor SEO conversion | Endless hourly maintenance retainers | Measurable latency drop, higher conversion & reclaimed sprint capacity |
