psychology_alt

Deployment Fear

Removing the fear of breaking production on Fridays.

How I Work

A systematic, safety-first approach to engineering.

01

Review & Audit

Deep dive into existing code, logs, and infrastructure to identify risks and bottlenecks.

02

Propose Plan

Outline safe, practical improvements prioritized by impact and stability.

03

Implement Safely

Execute changes with minimal disruption, utilizing feature flags and incremental rollouts.

04

Monitor & Support

Set up alerting and monitoring to ensure long-term health after deployment.

CI/CD & Infrastructure Focus

I don't just write code; I build the machinery that delivers it. My philosophy centers on automation that prevents human error.

Selected Case Examples

Real scenarios where stability was restored.

Legacy System Stabilization

Maintained and stabilized a 7-year-old production system suffering from daily downtime. Refactored critical bottlenecks and updated dependencies, resulting in 99.95% uptime over 12 months.

CI/CD Pipeline Implementation

Replaced a manual, error-prone FTP deployment process with a robust GitHub Actions pipeline. Introduced automated testing and staging environments, reducing deployment failure rate by 100%.

End-to-End Infrastructure Migration

Migrated a full-stack application from a costly managed service to a Dockerized VPS setup. Configured Nginx reverse proxies, SSL automation, and database backups, cutting infrastructure costs by 60%.

Tools & Stack
