02ABOUT

I BUILD THE SYSTEMSBEHIND THE SCREEN.

Backend engineer with 4+ years of experience building event-driven and high-throughput services.

My work focuses on realtime communication, messaging systems, database performance, distributed flows and production reliability.

I am comfortable owning services end-to-end — from architecture and implementation to deployment, observability and incident investigation.

I code AI-assisted every day, with Claude Code and Codex wired into the workflow.

Backend is the specialty.

I ship the client side when the feature needs it.

I BUILD THE MACHINERY BEHIND THE PRODUCT.

    Backend Engineer

    Vortech Service Company Limited

    May 2025 — Present

    Realtime gaming platform covering wallet, transactions, game state and user activity.

    • Built and operated event-driven backend services in Node.js, exposing REST and gRPC APIs.
    • Hardened Kafka consumers — manual offset commit, retry/DLQ strategy, heartbeat tuning, idempotent handlers — cutting duplicate and lost-message incidents.
    • Designed distributed flows spanning API gateway, WebSocket services, Redis, message queues and third-party integrations.
    • Led production incident investigation: log and trace analysis, root-cause identification, permanent fixes rather than restarts.
    • Ran services across dev, staging and production with Docker and CI/CD pipelines.

    PREVIOUSLY · Back End Developer · Feb 2023 — Jul 2023

    Internal web platform, POS and retail operations.

    Internal Web Platform

    TEAM OF 4
    • Built backend APIs for invoicing, promotions and reporting.
    • Cut query time on large datasets by moving heavy aggregation off the request path into Kafka/RabbitMQ workers.
    • Integrated payment webhooks with third-party providers (Onelife, MoMo).
    • Added centralized logging and tracing to microservices via Elasticsearch, reducing debugging time on production issues.
    • Built the React admin screens for invoicing, promotion and reporting alongside the APIs behind them.
    • Mentored 2 engineers on debugging and code quality.

    POS & Internal Operations App

    TEAM OF 3 · FLUTTER
    • Improved POS startup and operation speed by 30%.
    • Implemented async processing for high-volume invoices with offline-safe data integrity.
    • Shipped promotion and loyalty program integration.

    Platform Migration

    FIRST 6 MONTHS
    • Migrated the codebase from Express.js to NestJS.
    • Redesigned and optimized the database schema; set up sharding, replication and backups.
    • Added unit and end-to-end integration tests; configured CI/CD pipelines.

TOOLS I BUILDFOR MY OWN STACK.

Public repositories, built in the open.Keyboard-first desktop clients and a text editor written from scratch.

FEATUREDRUST

Netherize Editor

GPU-accelerated text editor built from scratch — no GC, frames rendered straight through the GPU.

  • Vim-style modes, EasyMotion-style leap, command palette, fuzzy file picker, multi-buffer
  • tree-sitter syntax highlighting for 17 languages · 83 built-in themes (TOML runtime)
  • Async LSP client, embedded PTY terminal, atomic durable saves, AI chat panel
  • Rust
  • wgpu
  • tree-sitter
min-devtools

The `_min` desktop family — minimal, keyboard-first clients for the exact stack I run in production. One shared design system, one family of apps.

  • Rust
  • Tauri
  • React
  • TypeScript
requests_minPostman/Bruno-style API client — REST, WebSocket and reflection-based gRPC, no protoc.kafka_ui_minKafka/Redpanda client — topics, watermarks, tail messages, full-topic search with JS filters.redis_minRedis/Valkey client — SCAN-based key browser, per-type editors, full REPL console.elastic_minElasticsearch client — Monaco query editor, custom TLS, no CORS proxy needed.git_minGit client built around the commit graph — staging, merge and conflict resolution, lazygit-style keys.log_minLog viewer and dev command runner — rotation-aware tail, 200k-line ring buffer.design_systemsShared tokens.css / themes.css that make every _min app read as one family.
