Roadmap and Demonstration¶

Roadmap¶

Phase	Goal	Changes	Exit criteria
v1	Basic transcription	upload, async transcription, status, download	stable processing of long files
v1.1	Operational resilience	stuck job detection, quota and budget alerts, old log cleanup, old file cleanup	predictable operation without manual monitoring
v2	Transcript post-processing	speaker-aware summarization	user receives not only a transcript but also a brief summary
v3	Format expansion	additional formats, metadata extraction	less manual preparation of source audio and transcript post-processing

This project demonstrates my ability to:

translate a personal/operational need into requirements, constraints, and an architectural solution;
design a serverless process accounting for long asynchronous operations;
use AWS services to minimize ongoing costs;
bypass API Gateway/Lambda limits via direct upload to S3 object storage;
design a state machine for the job lifecycle;
apply Cognito, JWT, and presigned URLs for restricted file access;
document architectural trade-offs through ADRs;
use Terraform for reproducible infrastructure deployment.
