Mess Ledger
Feb 2026 – present
A cost-splitting app for shared households, where several people cook together and split grocery and meal costs monthly. Shipped to app stores with subscriptions and ads; the API emits an OpenAPI spec and the mobile app regenerates a typed client from it, so a breaking change fails at compile time.

CV Analyzer AI Agent
Jul – Aug 2025
A recruitment assistant that reads a pool of CVs and ranks them against a job description through a RAG pipeline, so a recruiter gets a structured comparison rather than a folder of PDFs. I built the real-time parsing, the semantic-search API, chat memory, and the PII anonymisation that runs before anything reaches the model.

A deliberately over-engineered task manager, built to exercise a production AWS stack end to end rather than read about it. VPC, ALB, ECS Fargate, RDS, ElastiCache, SQS and Secrets Manager, with Testcontainers and LocalStack so tests hit real infrastructure and CI ending in an OIDC-authenticated push to ECR.
