What I'm looking for

I’m looking for a senior backend role where I can build low-latency, event-driven systems—ideally in trading/blockchain—owning architecture, performance, and production reliability end to end.

I build scalable backend services and trading workflows with a strong focus on performance, reliability, and clean architecture. At Webcom Systems, I developed microservices for the decentralized exchange platform xchangeon.io and modernized legacy Node.js/React modules by porting performance-critical components to Rust.

I’ve led migrations from monoliths to distributed systems, integrating real-time trading APIs and optimizing asynchronous processing with event-driven design. My work has used Rust, Golang, Node.js, Kafka, RabbitMQ, Redis, and NATS to improve inter-service communication and backend scalability.

I also have product and platform experience across ecosystems—from deploying a Swift-based trading iOS application to solving long-standing data consistency issues in large distributed systems. As Project Lead Developer at SimplicityLabs, I built secure backend and infrastructure services, including eBPF-based firewalling, secure VPC/VPN networking, and sandbox isolation with QEMU/Podman/LXC/chroot, while wiring observability using Prometheus.

My blockchain background spans DEX/DAO/ICO/IDO and wallet platforms, smart-contract integrations, and React-based dApp dashboards. I’ve worked deeply on L0/L1/L2 architecture, zkRollups and ZKP workflows with Circom, ZoKrates, SnarkJS, Cairo, and SP1, plus secure transaction systems using MPC-TSS and DKG—along with internal automation via AI LLM agents, RAG pipelines, and Ollama fine-tuning.
