PROJECT ARCHIVE
A closer look at the applications I’ve built, the problems they address, and the engineering decisions behind them.
A multi-tenant SaaS workspace with tenant-safe authorization, real-time collaboration, and background processing — designed so organisation boundaries are enforced by architecture, not developer memory.
ENGINEERING FOCUSA missed tenant boundary
A commerce system engineered for correctness under concurrency — atomic inventory, idempotent checkout, refresh-token theft detection, and order history that survives catalogue changes.
ENGINEERING FOCUSPreventing overselling and deadlocks
A full-stack messaging application with direct and group chat, media sharing, and WebRTC calls — built around ordered message persistence, idempotent write APIs, and server-enforced conversation membership.
ENGINEERING FOCUSOrdering messages across retries and membership changes
A full-stack publishing platform where the interesting work starts after CRUD — server-enforced admin boundaries, comment moderation, input validation, rate limiting, and secure public APIs.
ENGINEERING FOCUSProtecting privileged operations
A resume intelligence tool that turns uploaded PDFs into structured candidate profiles, skill and role recommendations, resume scoring, and admin analytics over collected results.
ENGINEERING FOCUSHandling noisy resume signals
