United StatesWhat I'm looking for
I am a Senior Software Engineer with deep experience building fintech infrastructure, billing and payment systems, and AI-powered developer tools. I focus on reliability, compliance, and scalable event-driven architectures that support high-throughput financial workloads.
At Meta I led decomposition of legacy services into domain-aligned microservices, designed high-throughput event pipelines handling ~500K daily events, and architected internal billing and reconciliation services with auditable transaction logging. I improved P95 API latency by 70% and reduced MTTR from 45 to 12 minutes through query optimization, partitioning, distributed tracing, and SLO-based frameworks.
I build production-grade LLM integrations and AI-assisted tooling with prompt templating, schema validation, and sensitive-data redaction while partnering with security and privacy teams to implement MFA and auditable access controls for regulated features. I bring strong SQL skills, distributed systems design, and a pragmatic, observability-first approach to reliability and compliance.
