Background

I'm a Linux Systems Engineer with over 5 years of experience building and maintaining production systems. I help businesses create custom software solutions that are reliable, scalable, and easy to maintain.

From full-stack web applications to container orchestration and monitoring, I handle the full lifecycle — design, development, deployment, and ongoing operations.

End-to-End Delivery

From requirements to production — I own the full stack so nothing falls through the cracks.

Production-Grade Infrastructure

Every project gets proper CI/CD, monitoring, and security from day one.

Long-Term Reliability

I build software that runs itself — clean code, automated deploys, and observable systems.

What I Can Do for You

Custom Software Development

Full-stack web applications tailored to your business needs. Clean architecture, tested code, and built for maintainability.

DevOps & Consulting

CI/CD pipelines, Kubernetes, Docker, and Ansible automation. I also audit existing workflows and help teams adopt best practices and tooling.

Cloud & Monitoring

Azure cloud deployments with full observability — Prometheus metrics, Grafana dashboards, and alerting that actually works.

Security Consulting

System hardening, security assessments, and best-practice implementation. Keep your infrastructure locked down.

Real-World Delivery

Personal Project

3NDURE.com

A full-featured sports coaching platform built entirely from scratch. 3NDURE connects athletes with coaches through training plans, workout tracking, and performance analytics.

This project demonstrates end-to-end delivery: full-stack application development, self-hosted infrastructure, CI/CD automation, and a complete observability stack.

  • Full-stack web application — frontend & backend
  • Self-hosted on hardened Linux infrastructure
  • CI/CD with automated testing & deployments
  • Prometheus, Grafana & full observability stack
  • Container orchestration with Kubernetes
