Professional Projects

At the outset of my career, much of which I spent as a Product Manager, I had the privilege of navigating the realm of smart factory manufacturing quality. This role taught me invaluable lessons in coordinating with diverse stakeholders and mastering effective communication and operational strategies. During this period, I extensively explored hypotheses, developed systems, and gained firsthand experiences of both successes and failures. These experiences have become invaluable assets in my life's journey.

Invoice Portal
Role: Full-Stack Developer
As a full-stack developer, I led the design and implementation of an Invoice Portal from start to finish as a solo project. This system facilitates seamless external invoice submissions and manages internal, role-based approval workflows. By developing and maintaining the front-end with Bootstrap and JavaScript and the back-end with Django and MySQL, I ensured a smooth and efficient user experience.

The portal features real-time payment monitoring, alerts, and budget aggregation tools, enabling clear financial oversight. My work on this project resulted in $325K/year in cost savings and enhanced operational efficiency by saving 0.75 hours daily for 50 users, translating to a significant improvement in budget control and productivity.

Web Site
Role: Web Developer
I built a simple website for a lawyer friend using Wix. The site features basic functionalities like a blog and email, but I dedicated significant effort to enhancing the UI/UX for improved user convenience. I also experimented with SEO for the first time to help boost my friend's revenue. Creating something is always a joy for me.
