I like the part of software where a wrong number or a lost write is a real bug. Most of my work is in Go: risk systems that can replay any past state, collaboration servers that never lose an edit, and network automation that catches drift before it breaks anything.

Engineering Focus

BACKEND

Backend & Data Systems

Go services and REST APIs on PostgreSQL and Redis: multi-tenant isolation with row-level security, append-only data models, background jobs and usage-based billing.

REAL-TIME

Real-time & Distributed Systems

WebSocket services and CRDT-based collaboration (Yjs) with durable persistence, horizontal scaling and conflict-free concurrent editing.

FINTECH

FinTech & Risk Systems

Point-in-time market data, exact-decimal valuation, reconciliation, stress testing and ledgers where every number can be traced back to its source.

INFRASTRUCTURE

Network Infrastructure & Automation

Reproducible network labs and intended-state automation: OSPF/BGP/IPsec topologies, NetBox-driven Ansible deploys, rollback and drift detection.
