You do not need more tools. You need systems that do the work.

01 / OVERLOAD

Seven apps before breakfast

Orders, messages, spreadsheets, and team chats all hold part of the answer—while your time disappears.

02 / MISSED SALES

Customers wait, opportunities leave

Buyers expect a prompt response. Your team also needs focus. A reliable system protects both.

03 / REPETITION

Reports consume the weekend

Work that software can handle is still taking time away from the people who create real value.

Give repeatable work to software. Keep judgment with people.

I map how your business actually operates, identify the automation opportunities in your niche, then build the smallest reliable system that removes the bottleneck. From Telegram bots to ERPNext, every integration has a practical job.

  • Web apps and portals built around your team's workflow
  • Telegram bots for operations, approvals, alerts, and reporting
  • ERPNext implementation for structured inventory and order management

I’m Hoàng Vũ Thạch, your direct technical partner.

I am a Fullstack Developer & Automation Engineer with 3+ years working in Node.js, NestJS, Next.js, and TypeScript. I turn unclear, manual processes into focused software your team can adopt.

I work remotely with international clients and communicate directly—from discovery and scope through delivery and handover. The aim is not more technology; it is a system that fits your business, solves a measurable problem, and remains maintainable.

Practical systems for growing small businesses.

Every build starts with the real process and the specific niche you operate in—not a recycled template.
