Production reliability and incident management

  • Prepare structured Root Cause Analysis (RCA) reports for production incidents, covering business impact, incident timeline, contributing factors, and evidence-backed root causes.
  • Define and track corrective and preventive actions (CAPA) with clear owners, priorities, deadlines, and validation criteria to prevent recurrence.
  • Collaborate with engineering, operations, and business stakeholders on incident communication, recovery follow-up, and continuous improvement.

Engineering strengths

  • Java 21 and Spring Boot 3.5.10 modernization
  • OOP, SOLID, design patterns, LLD/HLD, multithreading and concurrency
  • Data structures and algorithms, distributed systems, and Agile/Scrum delivery
  • AWS services including EC2, S3, and RDS; Docker and Jenkins CI/CD

Engineering approach

I am an evolving modern software engineer combining strong software fundamentals with AI-native development workflows. I use coding agents such as Codex Cloud and OpenCode to accelerate research, implementation, debugging, testing, and iteration - while retaining ownership through code review, validation, and engineering judgment.

  • Start with the business problem and measure outcomes, not lines of code.
  • Own delivery end to end: requirements, architecture, implementation, UI, deployment, and production support.
  • Design for security, maintainability, scalability, and auditability from the beginning.
  • Communicate clearly with engineering, operations, and business stakeholders during delivery and incidents.
  • Use AI as an engineering multiplier while validating generated solutions through code review and testing.
  • Learn unfamiliar domains and technologies quickly when the problem requires it.

Let's connect

I enjoy connecting with engineers, builders, and curious people who care about reliable systems, developer tooling, and practical AI. If something here helps you, or you see a problem worth building together, say hello.

Building reliable systems, automating meaningful work, and learning what comes next.
