Internal Web App Suite

PT Ecsconstruksi

Freelance Full Stack Developer

Overview

Led end-to-end development of scalable internal web applications for a construction company, serving as the sole developer responsible for architecture, implementation, and delivery.

Worked directly with multiple stakeholders across departments to gather requirements, define workflows, and iterate rapidly on functionality — balancing delivery speed with long-term maintainability.

Built responsive, production-ready systems using HTML, CSS, JavaScript, and Tailwind CSS for the frontend with MySQL for structured relational data management.

Delivered all systems on time with full stakeholder sign-off, with post-deployment support through the end of the engagement.
