Tätigkeitsbeschreibung

During my time at Hashnode, I spearheaded several key projects that significantly enhanced the platform’s functionality and user experience. Here’s a summary of my contributions:

Mobile App Development: Created a mobile app using React Native and Expo, featuring:
- Native HTML rendering for a seamless blog-reading experience.
Engaging animations to enhance user interaction.
- An audio background player, enabling users to listen to blog posts while
multitasking.
- A custom tab bar with smooth scrolling animations.

API Migration: Developed the Hashnode public GraphQL API, successfully migrating core features from the old API. This upgrade empowered users to build custom frontends for their blogs, while Hashnode managed their data.

API Enhancements: Migrated critical APIs for writing and draft management to the new GraphQL API.

Hashnode Pro Plan: Implemented key features for the Pro plan, including payment management and associated APIs.

Draft Management: Created a backup system, allowing users to save their drafts directly to GitHub.

Automated Posting: Developed a feature to automatically share blog post summaries on X.

Feed System Development: Built a scalable feed system leveraging hot ranking algorithms, utilizing technologies such as:
- AWS StepFunctions
- Redis Cache
- AWS EventBridge
- Apollo

Domain Verification Optimization: Rewrote the custom domain verification process using AWS StepFunctions for enhanced reliability.

Codebase Optimization: Optimized the codebase to lower operational costs.

Documentation Project Leadership: Led the backend implementation of the Hashnode Docs project:
- Developed core APIs and business logic, bringing the product to a
customer-ready state.
- Onboarded initial customers and implemented features based on their
feedback.
- Created a GitHub integration for seamless documentation publishing from
repositories.
- Developed a Hashnode CLI tool for verification of documentation projects
before publishing.

Über mich

Hi, I'm F.! I'm a passionate software engineer specialising in building serverless applications on AWS, with a strong foundation in both frontend and backend development.


I started as a Java developer 10+ years ago, learned the basics of networking and the corporate life, and finally moved from backend development over to creating mobile apps during my bachelor's degree. The first apps had a strong focus on Android - in a time before Kotlin was a thing. What changed a lot of things was the introduction of React-Native, which I first used in a Hackathon back in 2016. But, having the app or a frontend alone does not really give you a working product. And the time of a student is also limited. To give me some more space for creativity, I hoped on the new cool thing back then: Serverless (triggered by the introduction of AWS Lambda). This roughly summarizes my journey up until now and the focus I currently have: Serverless and mobile applications.

The beauty of this combination is that you can build everything on your own in an unbelievable speed. I use serverless and cloud-agnostic technologies to minimize the costs, maintenance and setup time of the infrastructure. It makes building new stuff super easy and can be applied to a lot of different use cases.

Today, I work as an independent developer, crafting mobile apps and serverless solutions for a diverse client base. I'm also diving into content creation, sharing my expertise and experiences with the developer community through various channels.
