What it does

Biocraft simplifies the resume creation process for mobile users. The app offers a variety of clean, professional templates that users can customize with their personal information, work experience, education, and skills. Once filled, the app generates a high-quality PDF that can be shared via email, messaging apps, or downloaded for printing. QR code support allows quick digital sharing of resume cards.

My contributions

Template Engine: Designed the template system allowing users to select from multiple pre-designed layouts with different visual styles and color schemes
PDF Generation: Built the PDF rendering pipeline that converts user-entered data into print-ready documents with proper formatting, typography, and page layout
QR Code Integration: Added QR code generation for resume cards, enabling quick sharing of contact information and resume details over NFC or messaging apps
Local Data Persistence: Implemented Room Database for offline access to resume data, allowing users to save multiple versions, auto-draft edits, and resume work without an internet connection

What I learned

Biocraft was a crash course in end-to-end app development — from concept to Play Store. Building a PDF generator required understanding document layout, pagination, and typography on Android, which goes far beyond typical UI development. Managing local data with Room Database taught me about data integrity, query optimization, and migration strategies. Seeing the app live on the Play Store was a milestone — it shifted my mindset from building things for myself to building things for users, introducing a new layer of considerations around UX, privacy, accessibility, and real-world usability.
