What I'm looking for

I seek roles building scalable, resilient cloud-native systems in fintech or payments, with strong engineering standards, mentorship opportunities, and impact on product and reliability.

I am a seasoned senior software engineer with 6.5+ years building high-throughput, low-latency distributed applications, focused on cloud-native banking and operations platforms. I have led greenfield onboarding engines, migrated critical workflows to more reliable orchestration, and delivered AI-powered automation to reduce manual verification work.

My background includes designing event-driven systems at scale, optimizing performance and costs, mentoring engineers, and owning end-to-end domain features such as CDR and KYC/KYB. I consistently drive operational efficiency and resilient architectures while collaborating closely with product and business stakeholders.
