• Prepared production environments for new projects using Nomad and Consul, ensuring seamless deployment and orchestration.
• Enhanced monitoring and alerting mechanisms for critical system components using Grafana, leading to improved system observability and faster incident response.
• Secured infrastructure by implementing HashiCorp Vault for secrets management, bolstering system security.
• Optimized large-scale data processing workflows to reduce database load, including designing and implementing a unique ID generation mechanism to prevent duplicates and improve performance.
• Collaborated with development teams to embed observability practices and enhance system performance under high-load conditions.
• Built an internal drift-detection tool that periodically audits production services deployed in Nomad against source configuration in Azure DevOps — surfacing version mismatches, config diffs (git-format), and stale dependency versions. Includes S3-backed historical reporting and LDAP-based access control, with SRE-only write endpoints and read access for other teams.

• Contributed to the development of large-scale backend systems for mobile financial services.
• Participated in end-to-end development, including backend service implementation, system integration, and deployments.
• Supported the launch of a major project enabling millions of users to access mobile-based loans.
• Helped improve financial inclusion through scalable and reliable FinTech infrastructure.

• Worked on performance optimization in the OpenJDK source code.
• Implemented the Binary Optimization and Layout Tool (BOLT) to improve instruction layout and execution flow.
• Developed call-chain clustering heuristics to optimize runtime performance.
• Gained practical experience in compiler internals, low-level systems profiling, and runtime optimization.
