I'm a Software Engineer with 2+ years of experience building production systems in fintech. I started as a Frontend Developer crafting React interfaces, and today I work as a Serverless Engineer, designing event-driven, cloud-native backends on AWS — Lambda, EventBridge, Step Functions, and the wider serverless ecosystem.

My work spans the full stack: streaming APIs, durable cross-account workflows, content architecture with Sanity CMS, and the CI/CD pipelines that ship it all.

Cross-Account Account-Deletion Saga

Durable orchestration erasing a user across 3 AWS accounts — cancellable, auditable, provable.

durable-executioncross-accountcompliance

Engineering highlights

  • ›Callback-proxy pattern so durable workflows receive cross-account completion signals
  • ›Two-phase deletion: grace window, transactional cancel, then irreversible execution with lockout
  • ›Audit-grade trail — per-service records, S3 archive, forensic runbook

Glance Dashboard

centerpiece

the observability dashboard that watches my node

Self-hosted personal dashboard with custom Node.js microservices — GitHub security advisories, kernel.org LTS tracking, and a system-stats panel (power monitoring, disk health, network stats). Deployed via Docker Compose with health checks and auto-start.

Primary runs on the home node — currently down. An emergency copy stays live on Render.

local analytics · laptop-side

Two local analytics CLIs — claude-stats (where my Claude Code spend goes: cost by model, cache hit-rate, top tools / skills / subagents) and battery-stats (real screen-on-time, drain rate, battery health). DuckDB on disk, self-contained HTML dashboards, no cloud or telemetry.
