You will get a custom full-stack web application or SaaS MVP
Project details
Need a scalable web application, a SaaS MVP, or a complex internal dashboard?
Building a dynamic app isn't just about writing code—it's about architecting a system that won't break when your user base grows. As a Lead Full-Stack Developer with a deep enterprise background in Product Management (PM) and Quality Assurance (QA), I build robust, secure, and scalable web applications.
🚀 What I bring to your project:
Full-Stack Architecture: From secure database design (SQL/NoSQL) to responsive front-end interfaces, I handle the entire tech stack.
Complex Business Logic: Like my multi-platform expense tracking SaaS, I excel at building complex algorithms, user workflows, and multi-platform integrations (PWA, LINE LIFF, etc.).
Enterprise-Grade QA: I implement automated testing (Pytest/Selenium) and rigorous manual QA. You get bulletproof, scalable code—not a buggy prototype.
PM Product Thinking: I help refine your requirements, design the optimal database architecture, and ensure the final product solves your actual business problems.
Let's build software that scales with your business. Contact me today to discuss your project!

Steps for completing your project
After purchasing the project, send requirements so WEI-LIN can start the project.
Delivery time starts when WEI-LIN receives requirements from you.
WEI-LIN works on your project following the steps below.
Revisions may occur after the delivery date.
Requirements Analysis & Architecture Design
As a PM and Lead Developer, I will first review your requirements in detail. We will finalize the business logic, design the database schema, and confirm the technical architecture before any coding begins.
Full-Stack Development
I will build the robust backend logic (database, APIs) and the responsive frontend UI (including PWA/mobile views if required). I will keep you updated throughout this phase to ensure we are aligned.
