Led end-to-end DevOps and infrastructure automation across environments using Docker, Kubernetes, Jenkins, Ansible, and Terraform.

Designed and maintained Jenkins CI/CD pipelines for automated build, test, deployment, rollback, and environment promotion. Developed automation to upgrade Kubernetes clusters with high availability, backward compatibility, and minimal disruption.

Operated containerized platforms on Kubernetes with autoscaling, resource optimization, and workload reliability. Provisioned and managed AWS and Azure infrastructure with Terraform (IaC) in a repeatable, auditable way. Automated provisioning and hardening with Ansible playbooks integrated into CI/CD. Delivered secure application traffic with Nginx, SSL/TLS, and Cloudflare (DNS, R2 storage), supporting reliable HTTPS and edge configuration.

Implemented Prometheus and Grafana for monitoring and alerting on Azure infrastructure; used Promtail (Loki) for log shipping and New Relic for APM/tracing where applicable. Managed Redis, PostgreSQL, and ClickHouse for caching, analytics, and persistence. Standardized releases to improve deployment reliability and reduce manual production changes.

Partnered with engineering and product on performance, reliability, and cost efficiency. Influenced DevOps strategy, tooling, and platform design. Reduced infrastructure costs using Azure VMSS autoscaling and optimized EC2 versus managed services where appropriate. Refined Prometheus alert rules and Grafana dashboards to reduce false positives and speed root-cause analysis. Supported incident response by triaging outages and performance regressions using metrics, logs, and platform tooling. Standardized container build and promotion workflows with ACR/ECR and documented runbooks for upgrades, rollbacks, and recurring maintenance. Managed certificate lifecycle, DNS, and Cloudflare/Nginx edge configuration to keep releases secure end-to-end.

Developed and maintained Laravel and CakePHP services integrated into Docker-based CI/CD for consistent deployments. Designed, implemented, and consumed RESTful APIs for web and mobile applications with scalability and maintainability in mind.

Optimized MySQL, PostgreSQL, and ClickHouse for transactional and analytical workloads. Integrated Firebase for real-time notifications and Microsoft SSO for secure, scalable authentication.

Partnered with QA and DevOps on testing, releases, monitoring, and production troubleshooting. Helped transition manual deployments to Jenkins and Docker pipelines, using Git branching and code reviews to improve quality. Used JavaScript/TypeScript and React where richer UI was required, integrating with shared backend APIs.

Delivered Laravel and CakePHP features using both server-rendered and API-first architectures so web and mobile shared the same backend. Applied framework conventions for sessions, CSRF protection, secure cookies, CORS, authentication, and HTTPS. Implemented pagination, filtering, and consistent JSON responses to keep web and SPA clients responsive.

Owned database migrations, indexing, and SQL tuning to maintain API performance as data grew. Used Redis for caching and Pheanstalk for asynchronous jobs, contributing to ClickHouse-based reporting and analytics alongside transactional systems.

Improved API usability through consistent validation, error handling, and backward-compatible changes. Delivered features through Jira-based sprints with coordinated QA handoffs. Diagnosed production issues across PHP, databases, Redis, Firebase, and SSO integrations. Debugged browser and client-server issues, including CORS, failed requests, and API performance, while supporting content caching and deployment practices aligned with Cloudflare.
