🚀 Scaling issues? Slow queries? Unstable deployments? I help SaaS platforms scale reliably, optimize infrastructure, and deploy with confidence. 📅 20+ years of experience 📦 70+ completed infrastructure & DevOps projects ⚡ Systems handling millions of requests monthly 💰 Helped clients reduce infrastructure costs by up to 45% 🚀 Improved deployment speed by 60% with automated CI/CD pipelines I’m a DevOps Engineer, AWS architect, cloud engineer, and AWS devops specialist focused on building high-performance, scalable cloud infrastructure for SaaS platforms, enterprise systems, and high-load applications. I work with startups and growing businesses to eliminate bottlenecks, optimize databases, stabilize deployments, and improve infrastructure reliability. I have strong hands-on experience with aws, Google Cloud, and Azure environments, including infrastructure automation, monitoring, container orchestration, disaster recovery, and production scaling. I also work as an azure devops engineer, building automated deployment pipelines and improving release workflows for scalable SaaS systems. My background also includes gcp devops environments for cloud-native applications and high-availability infrastructure. 🎯 Database & Performance Expertise I specialize in MySQL, PostgreSQL, MS SQL, MongoDB, Oracle, and high-load database optimization, including: • Query tuning & indexing strategies • Performance optimization • Backup & disaster recovery • Replication & high availability • Oracle RAC & Data Guard • Database scaling & monitoring I’ve optimized systems processing 200K+ events daily while reducing query execution time by up to 70%. 🎯 DevOps, Cloud & Infrastructure As an AWS architect and cloud engineer, I design and manage scalable cloud environments using: • AWS • Azure • Google Cloud • Docker • kubernetes • Terraform • Jenkins • GitHub Actions • GitLab CI/CD • n8n I build secure, automated infrastructure with Infrastructure as Code (Terraform), scalable deployment pipelines, and containerized environments optimized for reliability and performance. I also work with wordpress devops workflows including server optimization, deployment automation, CDN configuration, caching, scaling, and security hardening for high-traffic WordPress platforms. Additionally, I have experience with python devops environments, supporting Python-based APIs, automation systems, backend services, CI/CD workflows, containerization, and cloud deployment pipelines. 💡 What I Can Help You With • AWS devops & cloud infrastructure • CI/CD pipeline setup & automation • Docker & kubernetes orchestration • Infrastructure as Code with Terraform • Monitoring & observability systems • Database optimization & scaling • Backup, recovery & disaster planning • High-load SaaS infrastructure • Linux server administration • Production deployment optimization • Cloud migration & infrastructure modernization 💻 Infrastructure & System Administration • Linux, Unix, Windows Server administration • Oracle, PostgreSQL, MySQL, MongoDB, MSSQL administration • Active Directory setup & maintenance • RDS Apps & VDI environments • Apache, Nginx, CPanel, CentOS environments • Monitoring systems: Zabbix, Nagios, Splunk, Grafana • Cloud services: AWS, Azure, GCP • Kubernetes cluster management • Jenkins & automated deployment workflows • n8n ⚡ Results Delivered • Reduced downtime by 80% through infrastructure hardening • Improved deployment reliability across multiple SaaS products • Reduced cloud costs by 30–45% through infrastructure optimization • Automated CI/CD workflows reducing release cycles from hours to minutes • Built scalable environments supporting 100K+ active users I bridge the gap between infrastructure, backend systems, databases, and cloud architecture — helping teams ship faster while keeping systems stable, scalable, and secure. 👉 If your platform is growing — or struggling under production load — I’ll help you stabilize, optimize, and scale it for long-term reliability and growth. ⚙️ Core Expertise / Keywords AWS Architect, AWS DevOps, Cloud Engineer, Azure DevOps, Azure DevOps Engineer, GCP DevOps, Kubernetes, Terraform, DevOps Engineer, n8n, Docker, AWS, GCP, Cloud Infrastructure, Oracle DBA, PostgreSQL, MySQL, MongoDB, Performance Tuning, Query Optimization, Infrastructure as Code, Jenkins, GitHub Actions, Linux Administration, SaaS Infrastructure, Scalability, High Availability, Monitoring, Automation, Reliability Engineering
