What I'm looking for

I’m looking for a role where I can build fintech and AI-integrated distributed systems—fail-safe architectures, real-time platforms, and production-grade event-driven payments—working with teams that value reliability, observability, and scalable delivery.

I’m a Senior Full Stack Engineer designing and delivering end-to-end payment systems, real-time data platforms, and marketplace products. At WeiBlocks, I led a team of 4 engineers to ship Escrowly, a Kafka-based microservices escrow platform with transactional outbox, a double-entry ledger, and AWS KMS-encrypted wallet infrastructure.

I build systems that fail safely and scale predictably, from zero-loss payment guarantees to production recovery for failed event delivery. I’ve also engineered real-time aggregation across 20+ exchanges, and built multi-agent AI platforms with LLM orchestration, intelligent model routing, and RAG-style research pipelines—reducing manual workflows from ~6 hours/week to under 15 minutes.
