About

Over the past 25+ years, I’ve dedicated my career to solving complex technical challenges and delivering innovative IT solutions that drive business success. As a versatile freelance IT professional, I blend hands-on technical expertise with strategic leadership to help organizations optimize their technology stacks—from infrastructure and development to architecture and team building. Whether you need a problem solved, software built, or systems designed for scalability and reliability, I bring both depth of knowledge and adaptability to every project.

Technical Expertise:

My career began in IT Administration, where I developed a passion for building robust, secure infrastructure. Over the years, I’ve specialized in DevOps practices—including CI/CD pipelines, containerization (Docker, Docker-Swarm), and cloud platforms like AWS/Azure—to create agile environments that empower development teams. My expertise spans Linux system administration, database management (MySQL, MongoDB, PostgreSQL), and monitoring tools like Prometheus, Grafana, Zabbix, ensuring systems are efficient, scalable, and resilient.
On the development side, I specialize in crafting clean, maintainable code using PHP frameworks (WordPress, Laravel) and Python for backend automation/APIs. I’ve designed RESTful APIs that integrate seamlessly with modern frontend applications and third-party services, prioritizing performance and security at every layer.

Software Architecture:

Beyond coding and infrastructure, I thrive in architectural roles—designing systems that align with business goals while adapting to future growth. My approach balances technical debt reduction, cloud-native strategies, and microservices architecture patterns tailored to clients’ unique needs. Whether migrating legacy systems or building greenfield projects, I ensure scalability without compromising reliability.

Leadership & Collaboration:

Throughout my career—from small startups to enterprise environments—I’ve led cross-functional teams as a technical lead and mentor. I believe collaboration is key: bridging gaps between developers, stakeholders, and business teams to deliver projects on time and budget. My focus is fostering innovation while maintaining clarity in complex workflows—from sprint planning to post-mortems—and ensuring teams operate at their best.

Why Partner With Me?

With decades of experience troubleshooting, designing, and building technology ecosystems—from high-availability clusters to full-stack applications—I offer a rare combination of big-picture thinking and hands-on execution. My adaptability means I’m comfortable jumping into code, optimizing infrastructure, or guiding teams toward technical excellence—all while staying current with emerging trends like AI/ML integration and serverless computing.
