About Me

I'm a Software Engineer specializing in AI Automation, Cloud Engineering, and DevOps, with 7+ years of experience building, deploying, and scaling production-grade systems. My background in PHP/Laravel evolved into full ownership of cloud infrastructure, automation workflows, and system reliability.

I design and operate scalable systems using AWS, DigitalOcean, Docker, CI/CD (GitHub Actions), Linux, and Nginx. I build automation workflows (n8n, APIs, AI-assisted processes) that eliminate repetitive tasks, improve operational efficiency, and reduce infrastructure costs for businesses.

My experience spans backend engineering, cloud deployments, and production reliability across teams at SAMBA-DATA R&D, SwitchCoins Global, BFA Digital Tech, and multiple startups. I’ve built REST APIs, optimized databases, automated deployments, and maintained high-availability systems used in real-world environments.

I focus on automation, scalability, security, and cost optimization—helping teams ship faster while keeping systems stable and predictable. I also contribute as a technical writer, documenting CI/CD, cloud workflows, and practical engineering solutions.

Currently, I’m deepening my expertise in AI-driven automation, cloud-native systems, and platform engineering, and I’m open to remote opportunities where I can help build efficient, intelligent, and high-impact systems.
