Projects

Referral Management App

FairShare

Tech Stack: Swift (SwiftUI), Python (FastAPI, Celery), MongoDB, Redis

GitHub: fairShare, fairShareAPI

Problem: Referral sharing platforms often favor early adopters, creating unfair advantages for some users while others rarely get opportunities.

Solution: Built a queue-based referral management system using priority algorithms to ensure fair distribution of opportunities across all users. Implemented real-time queue processing with Redis caching and OAuth2 authentication for secure access.

Results: Validated fairness algorithms through 50+ simulated scenarios, achieving target distribution goals.

FInance tracker

Ledger

Tech Stack: .NET, Avalonia UI, MVVM Pattern, C#

GitHub: AviniLedger

Problem: Managing lending business records became complex with multiple borrowers, different payment schedules, and difficulty tracking individual payment histories.

Solution: Built cross-platform desktop application using .NET with Avalonia framework to ensure macOS compatibility. Implemented MVVM pattern for clean architecture, enabling users to track lending records, view daily/weekly payment schedules, and generate printable reports for individual borrowers.

Results: Streamlined family lending business operations with organized record-keeping and automated schedule generation.
