How we can work together to build your solution.

Every business engagement begins with a clear written scope and technical architecture before coding starts. Get a tailored solution built specifically for your business goals.

01 · For founders & SMEs

MVP Sprint

You have a business idea and need a production-grade product launched fast.

  • Scoped build to a working v1 web or mobile app
  • Hosting, CI/CD pipeline, domain & auth setup
  • Complete handover docs so you own your codebase
Typical timeline: 4–8 weeks
02 · For existing products

System Rescue & Refactor

Your current app is sluggish, unstable, or abandoned by previous developers.

  • Codebase & cloud architecture audit
  • Prioritised fix plan, ranked by business risk
  • Hands-on execution and modernization
Typical timeline: 2–6 weeks
03 · For regulated companies

Security & PDPA Audit

You handle customer/financial data and cannot afford compliance or breach risks.

  • SQLi / XSS / SSRF / IDOR / auth vulnerability scan
  • PDPA 2010-aligned findings, severity-ranked
  • Actionable remediation code & architectural fixes
Typical timeline: 1–2 weeks
04 · For GLCs & growing teams

Embedded Senior Engineer

You need dedicated senior ownership and technical leadership without full-time overhead.

  • Embedded technical leadership, remote or hybrid
  • End-to-end system architecture & code quality
  • Mentoring your internal engineering team
Typical timeline: Retainer / engagement-based
Development process

01

Discovery

Clarify business goals, user requirements, and technical constraints before building.

02

Spec & Sign-off

Architecture, data model, APIs, and milestones signed off before coding starts.

03

Build

Production-ready implementation with automated tests. No shortcuts or placeholders.

04

Security Review

Tested against OWASP Top 10, auth bypasses, and data leaks before launch.

05

Handover

Full source code, API runbooks, and documentation so you retain 100% ownership.

FAQ

Frequently asked questions by business clients.

What is your typical turnaround for building a business software solution?

Turnaround depends on scope — a focused MVP or custom internal tool runs 4–8 weeks, while a security or architecture audit takes 1–2 weeks. You get a written timeline and milestone plan before work commences, not an estimate that slips silently.

Do you sign NDAs (Non-Disclosure Agreements)?

Yes. Several active client systems (e.g., JawiKids) are under NDA. I am happy to sign your standard NDA prior to our initial discovery discussion.

I have a business idea or operational problem, but no technical spec. Can you help?

Yes — discovery is designed specifically for this. We translate your business goals and operational bottlenecks into a concrete technical specification and architecture before writing code.

Do you work with non-technical founders and business owners?

Often. Technical trade-offs are explained in plain, pragmatic terms with decisions documented in writing, ensuring you maintain full clarity and strategic control over your product.

Are you open to international / remote clients as well as local Malaysian businesses?

Yes — based in Malaysia, I work effectively with remote clients worldwide across time zones, with on-site availability for enterprise, GLC, and regulated-sector engagements within Malaysia.
