Services

Freelance software development, system development, bug fixing, and product revamp — scoped clearly so delivery stays on track.

  • Software development

    Custom software development for web, desktop, and mobile — plus APIs and internal tools shaped to your workflow, from MVP to production hardening.

  • System development

    System development and integration for internal platforms, operational workflows, and data connections across your stack.

  • Bug fixing

    Production bug fixing: reproduce, isolate, and ship durable patches with regression checks so issues stay resolved.

  • Revamp & modernization

    Product revamp and legacy modernization — refresh UI, strengthen the codebase, and migrate stacks while the business keeps running.

Who this is for

A short fit check so we start with the right kind of project.

A strong match when you need

  • Custom web apps, internal tools, APIs, or system integrations
  • Production bug fixing with a durable, tested patch
  • Revamp / modernization while the product stays online
  • A focused MVP or ops workflow (CRM, ERP-style, helpdesk, catalogues, portals)
  • Direct work with the engineer — WhatsApp or email

Usually a better match elsewhere

  • Brand or graphic design as the only deliverable
  • Game development
  • Long discovery retainers before a decision-maker or budget is set
  • Very large legacy rewrites that still need a defined first milestone
  • Projects that need a full product team on-site every day

How we work

  1. 01
    Message with context

    What you need, who uses it, deadline, and constraints (stack, hosting, budget band if you have one).

  2. 02
    Scope & quote

    I reply with the proposed scope, priorities, a rough timeline, and a fixed or capped estimate.

  3. 03
    Deposit & build

    Agree the first milestone, pay a deposit, then I ship in visible increments you can click.

  4. 04
    Handover

    Deployed or packaged delivery, short notes on how to run it, and optional follow-up fixes in an agreed window.

Helpful to include

  • Links or screenshots of the current system
  • Who the users are and what “done” looks like
  • Must-have vs nice-to-have
  • Preferred stack or hosting (or say you are open)

I reply on WhatsApp or email — usually within one business day. Hong Kong timezone.
