Project details

System down? Errors everywhere? I quickly find the root cause and fix it.

Production issues are stressful and expensive. I specialize in fast root cause analysis:
• Random crashes
• High CPU spikes
• Deadlocks & DB issues
• Broken APIs
• Queue/job failures

I don’t guess I trace, fix, and prevent future issues

About Jonathan

Jonathan T.Status: Offline
Senior Backend & DevOps Expert | Fractional CTO
5.0  (2 reviews)
Mandaluyong City, Philippines - 4:08 am local time
I help businesses fix slow, unstable, and unmonitored systems and turn them into production-ready, scalable, and reliable infrastructures.

With 10+ years as a CTO and Senior Software Engineer, I specialize in backend performance, server optimization, and observability. I’ve rescued systems that were crashing, slowed down by heavy load, or invisible due to lack of monitoring so businesses can focus on growth, not downtime.

In addition to technical delivery, I am available as a Fractional CTO, providing strategic guidance on technology, architecture, and team scaling helping startups and SMEs make smart technical decisions without a full-time CTO.

Here’s how I can help you:

Backend Performance & Debugging
• Fix high CPU usage, slow APIs, and memory leaks
• Optimize MySQL/PostgreSQL queries and caching (Redis)
• Identify N+1 issues and slow background jobs

Production VPS / Server Setup
• Secure and hardened Linux servers (AWS, DigitalOcean, VPS)
• Web stack installation (Nginx, PHP, Node.js, DB)
• CI/CD ready environments and backup strategies

Monitoring & Observability
• Metrics, logs, and tracing for full system visibility
• Dashboards with Grafana and alerts for proactive problem-solving
• Error tracking with Sentry and tracing with OpenTelemetry

Incident Investigation & Root Cause Analysis
• Debug production issues fast (crashes, errors, deadlocks)
• Identify root causes and implement reliable fixes
• Provide recommendations to prevent recurring problems

Fractional CTO Services
• Technology strategy and roadmap planning
• Architecture guidance and team scaling advice
• Vendor & tool selection for cost-efficient, high-quality results
• Technical risk assessment for startups and growing businesses

Why work with me?
• I don’t just “install servers” or “run commands” I solve real business problems
• You get actionable results, not just scripts or tutorials
• I communicate clearly and work in a structured, documented process
• Available for strategic CTO-level guidance without a full-time hire

Industries & Tech Stack:
• Laravel, Node.js, Go backends
• MySQL, PostgreSQL, Redis
• AWS, DigitalOcean, Linux VPS
• Monitoring: Grafana, Prometheus, Sentry, OpenTelemetry

How I work:
• Assess your system, gather metrics, and identify pain points
• Implement fixes, optimizations, and monitoring
• Deliver a stable, production-ready system with documentation
• Optional ongoing support for high-availability and monitoring
• Strategic guidance as your fractional CTO

Ideal Clients:
• Growing SaaS platforms
• E-commerce systems with high traffic
• Startups launching new apps
• Businesses that want reliable, monitored, and fast systems
• Founders seeking fractional CTO guidance
