What I build with

The tools, languages, and infrastructure I reach for most — the stack behind the work (and behind this site).

// Languages & core

  • TypeScriptStrict mode, end to end — the default for everything.
  • Node.jsThe runtime under most of what I ship.
  • ZodOne schema → validation + types, shared across the stack.

// Backend & data

  • NestJSPrimary backend framework — modular, DI, guards.
  • Fastify / ExpressHTTP layer under Nest, or standalone when lean.
  • Hono + DrizzleEdge-friendly stack for newer, lighter services.
  • PostgreSQLMy default database; TypeORM or Drizzle on top.
  • MongoDB / MySQLWhere the domain or the client calls for it.
  • RedisCaching, rate limiting, queues, and locks.

// Messaging & async

  • Apache KafkaEvent backbone for multi-service ecosystems.
  • BullMQRetryable background jobs on Redis.
  • AWS SQS + EventBridgeManaged queues + serverless scheduling.

// Frontend

  • Next.jsReact framework of choice — App Router, RSC, ISR.
  • ReactFor everything interactive.
  • Tailwind CSSStyling the public side (this site included).
  • Ant DesignAdmin dashboards and internal tools.

// Infrastructure & cloud

  • AWSS3, SES, SQS, EventBridge, Rekognition in production.
  • DockerLocal parity and container deploys.
  • SupabaseAuth (JWKS) + storage when I want managed.
  • Vercel / RenderWhere the frontends and APIs run.

// Tooling

  • Turborepo + BunMonorepo orchestration + a fast package manager.
  • BiomeOne fast tool for lint + format.
  • VS CodeDaily editor.
  • zshShell — hence the terminal theme.
  • GitObviously.
