What I Do

  • Current Focus: Leading the architecture and implementation of client projects at my agency, from system design through production deployment.
  • Omnichannel CRM Architectures: Multi-tenant CRM SaaS with WhatsApp integration via Baileys (an unofficial WhatsApp Web library), Redis-backed sessions/queues, and strict per-tenant data isolation.
  • Private Travel Management Systems: Custom software for logistics, bookings, and day-to-day operations of private transportation companies.
  • E-Commerce & ERP Integration Platforms: Transactional sync between accounting, inventory, and e-commerce engines.
  • WordPress & Custom Themes: Building maintainable WordPress sites with Sage (Blade + Acorn), Tailwind CSS, and WooCommerce.
  • Cloud Infrastructure & DevOps: Deploying and managing VPS infrastructure (Ubuntu Linux, Contabo, AWS S3, Railway) with Docker multi-container orchestration.
  • Full-Stack Development: End-to-end delivery with Next.js (App Router), React, NestJS, Node.js/Express, TypeScript, PostgreSQL (Prisma ORM), and PHP tooling via Sage/Acorn (Laravel components under the hood).

Featured Projects

  • invencheck — Voice-driven physical inventory count PWA (NestJS + Prisma + PostgreSQL, Next.js client). CI runs lint, typecheck, unit and e2e tests against a real Postgres on every push. A voice-matching audit against a 938-item catalog found 78 silent incorrect matches (8.3%); after adding an ambiguity-gap check, that's 0/938, with 175 items now correctly flagged for operator confirmation instead of guessing.
  • CRM-Omnichannel — Multi-tenant omnichannel CRM SaaS (backend + frontend) with real-time WhatsApp integration via Baileys, Redis-backed sessions, and strict tenant isolation enforced on every query.
  • skycode-web — Trilingual marketing site + internal CRM/project dashboard with real auth, built on Next.js and PostgreSQL, with CI covering unit, integration, and e2e tests.
  • racing-bike — WordPress theme on Sage 11 (Blade + Acorn) with Tailwind CSS v4 and WooCommerce, including custom plugins for bike configuration and sizing.
  • don-kampo-API + don-kampo-front — Full-stack e-commerce platform (Node/Express API + React frontend) for a fresh-produce marketplace.
