Work Experience

Back-End Developer

[>>]
Migrated and refactored payment services (Bifast, Outgoing Payment, Intrabank) from C# to Go and from a Go monorepo to microservices, cutting the service call chain from 2 hops to 1 and enforcing idempotency under concurrent load via database sequences.
[>>]
Developed and maintained 6 payment API gateway services on Software AG webMethods ESB, building integration flows in IS Designer while keeping existing legacy integrations running alongside new feature work.
[>>]
Identified cache stampede risk on Redis-backed lookups and introduced Go's singleflight pattern: 1,000 concurrent requests to the same key hit the database only once, yielding a 143x reduction in memory overhead.
[>>]
Integrated AI developer agents into the C# to Go migration workflow, cutting sprint cycle time by an estimated 57%, validated through manual review before merge.

Full-Stack Developer

[>>]
Migrated a legacy JavaScript codebase to TypeScript across ERP and insurance applications, catching type errors at compile time and reducing production errors by 30% based on log analysis.
[>>]
Migrated the backend runtime from Node.js to Bun, increasing application throughput by 3x and reducing CPU usage by 50%, both confirmed in Grafana.
[>>]
Architected a standardized GitHub Actions CI/CD pipeline for 10+ applications, tripling deployment frequency with a 97% success rate across 5 environments.
[>>]
Deployed a comprehensive observability stack (Prometheus, Grafana, Loki), reducing the Mean Time to Detect (MTTD) for production errors by 50%.

Front-End Developer

[>>]
Developed custom web applications based on client requirements, with a focus on responsive and user-friendly design
[>>]
Collaborated with stakeholders to gather and analyze requirements for the POLRI dashboard, translating them into clear technical specifications
[>>]
Designed and implemented Helvetica web interfaces using React, HTML, CSS, and JavaScript
