Engineering interests
What Interests Me
I gravitate toward problems where complexity, correctness, and reliability matter more than a particular language or framework.
Distributed Systems
Designing asynchronous workflows that remain correct when dependencies time out, jobs fail, or requests are repeated.
Orchestration · Idempotency · Recovery
Financial Infrastructure
Building auditable financial movements, payment integrations, and reconciliation workflows where correctness is essential.
Ledgers · Payments · Reconciliation
Data & Performance Engineering
Migrating historical records, tuning queries, and modernizing databases without compromising referential integrity.
SQL · Indexes · Migration
Reliable AI Systems
Exploring persistent AI execution, streaming, cancellation, and stateful application workflows.
LangChain4j · Streaming · Persistence
Background
Beyond the code
My experience spans financial technology, banking infrastructure, enterprise software, and technical leadership. Working with critical banking systems shaped how I approach reliability and recovery.
