During my time at Smallpdf, I had the opportunity to introduce new features for which I had complete ownership. I was involved in all stages of development, starting from the initial phase where we conducted user feedback gathering and discovery. This extended to design exploration and technical research. In the engineering phase, I placed a strong emphasis on code quality and collaboration to ensure a seamless and outstanding experience for our millions of users. I continuously monitored the impact of my changes using various tools and kept a close eye on the platform's stability to prevent any degradation in the user experience. Additionally, I conducted data analysis using powerful tools to measure the impact of changes on user behavior, conversion rates, and long-term value.

The primary tech stack I worked with was predominantly React/Redux, written in TypeScript. However, I also had the opportunity to expand my knowledge by working with other languages like Go, which is our backend programming language. I devoted time to crafting SQL queries to extract insights from our tracking system, created dashboards to monitor ongoing experiments, and derived valuable insights from the data to inform the next steps for our product.
Projects I've been involved in:
- Introduced experiments to implement new tools for PDF processing and assessed the SEO impact.
- Enhanced acquisition and retention in the checkout process.
- Upgraded the Chrome extension from manifest v2 to manifest v3.
- Completely overhauled the user experience for the Chrome extension as part of an experiment to boost retention.
- Implemented a fast and reliable PDF preview using the pdfjs library on the tools result page.
- Maintained and upgraded the PDF editor, incorporating new features along the way (good knowledge of Apryse, formerly PDFTron).
- Updated email campaigns associated with the free trial experience.
- Established and configured the authentication system for the new product, sign.com Show less
