About
Building resilient data platforms
for over a decade

I'm a Senior Cloud and Database Engineer with over a decade of experience designing and operating reliable data platforms for financial and enterprise applications. My work focuses on building highly available database systems across AWS cloud and hybrid environments using technologies such as MariaDB, MySQL, PostgreSQL, SQL Server, and MongoDB.

Over the years, I've worked extensively with AWS services including RDS, Aurora, EC2, and VPC to design resilient database architectures that support mission-critical systems. I specialize in database reliability engineering, performance optimization, replication strategies, and disaster recovery planning.

I'm particularly passionate about automation and operational efficiency. I use tools like Terraform, Python, and shell scripting to reduce manual operations, standardize infrastructure, and create repeatable, production-ready environments through Infrastructure as Code and CI/CD practices.

At the core, I enjoy solving complex infrastructure problems and helping organizations modernize their data platforms so they can run reliably and efficiently in cloud environments.

How I approach data platforms

When I work on database platforms, my focus goes beyond keeping systems running. I think about how those systems will behave under real production pressure for years to come.

Architecture & Cloud Platforms

Designing resilient database architectures across AWS with multi-region deployments, highly available clusters using RDS, Aurora, EC2, and VPC.

Reliability Engineering

24/7 production support for large-scale financial systems. Diagnosing performance issues, resolving replication failures, and maintaining stability.

Automation & IaC

Terraform, Python, CI/CD to reduce operational risk, standardize infrastructure, and create repeatable production-ready environments.

Performance Optimization

Tuning SQL workloads, optimizing execution plans, redesigning indexing strategies, and improving engine configurations for dramatic gains.

Security & Compliance

Encryption, SSL/TLS, IAM-based access control, CIS benchmarks, and compliance-driven privilege audits for regulated financial systems.

Disaster Recovery

Automated snapshots, cross-region backups, and recovery validation. Systems remain operational during infrastructure failures.
