What I'm looking for

I’m looking to build and scale backend microservices in fintech, owning end-to-end delivery—from databases and DevOps to QA—while optimizing real-time performance and shipping reliable releases under tight deadlines.

I’m a Backend Engineer with 4+ years delivering production-grade systems for platforms processing millions of daily transactions. I focus on microservices infrastructure and dependable delivery, especially where real-time performance and reliability matter.

At Deriv, I maintained microservices infrastructure serving 3M+ active traders across 20 global offices. I reduced backend latency for real-time financial data processing, integrated 10+ third-party APIs, and helped maintain 99.9%+ uptime for high-frequency trading operations.

At FortyAU, I shipped solutions across healthcare, entertainment, and business automation for US-based clients. I delivered full-stack features across PHP, C#, Angular, React & Kotlin, and I owned DevOps, QA, and DBA responsibilities simultaneously—eliminating handoff delays across 3 time zones.

I’m fast at picking up whatever the project demands, and I collaborate across teams to make architecture decisions under tight deadlines. I design database schemas (PostgreSQL, MySQL, SQL Server), work with Redis and Docker/YAML-based infrastructure, and build API-driven, real-time systems using Node.js, Perl, and Perl-Myriad.
