Knowledge map
The technical domains I work within — organized by depth of expertise and production experience.
Backend Architecture
Architecting production-grade backend ecosystems: service boundaries, API contracts, protocol strategy, domain modeling, and system topology that scales cleanly from monolith to distributed platforms.
Distributed Systems
Designing resilient distributed platforms with practical consistency tradeoffs, event choreography, failure recovery, and concurrency-aware state management under production load.
Fintech Engineering
Engineering correctness-critical financial systems across payments, investment flows, transaction lifecycles, reconciliation, settlement, and margin-sensitive architectures.
Java / Spring Ecosystem
Enterprise-grade JVM engineering across Spring Boot microservices, reactive architectures, secure backend infrastructure, and high-throughput backend systems.
Node.js / TypeScript
Full-scale backend and product engineering with Node.js ecosystems spanning NestJS, Express, SSR infrastructure, enterprise APIs, and developer tooling products.
Streaming / Messaging Infrastructure
Operational messaging systems for real-time event pipelines, asynchronous processing, stream consumers, and scalable cache-backed architectures.
Databases & Persistence
Polyglot persistence design across transactional, analytical, and document systems with schema strategy, optimization, and operational reliability.
Cloud / DevOps / Infrastructure
Shipping and operating production systems through CI/CD, Linux infrastructure, deployment automation, networking, and runtime performance optimization.
Product Engineering
Building complete products from infrastructure to interface: SaaS systems, internal platforms, analytics products, and desktop-grade developer tools.
Security / Reliability
Practical application security, system hardening, operational resilience, and defensive engineering for production environments.
