Portfolio & Case Studies
From problem to production
The Day Rate Limiting Almost Killed Our Dashboard
React + Express dashboard with multiple user roles (admin, operator, complainant) running in parallel tabs.
"Everyone thought it was a CORS bug… but it was our rate limiter silently triggering mass logouts."
- Fixed middleware order so CORS runs before rate limiting (CORS headers on 429s too).
- Switched production rate limiting from per-IP buckets to per-user buckets using req.user.id (NAT-safe).
- Killed the polling spiral by moving the dashboard to Socket.IO push updates instead of 3-second intervals everywhere.
~90–95% drop in API traffic, no more logout storms, and real-time updates without hammering the backend.
Real-Time Operational Pulse
Operational dashboard for high-stakes, multi-user queues.
"People were seeing stale data — so they’d click twice, or act on the wrong state."
- Integrated SWR for intelligent background syncing and cache revalidation.
- Added optimistic UI updates to eliminate perceived latency during critical actions.
No more UI flicker, fewer duplicate actions, and the data finally felt reliable during ops.
Dashboard Performance Overhaul
Admin interface for a high-concurrency operations environment.
"Users were waiting 6+ seconds for a page to load 1.2MB of largely useless JSON."
- Implemented 'Lite Projections' to fetch only visible fields for list views.
- Offloaded complex status logic from the client to the database via computed fields.
80% reduction in initial payload and zero browser memory pressure.
Professional Experience
Software Developer
Working on backend-heavy systems with a focus on APIs, automation, and long-term reliability. The work often sits close to product and business needs, thinking through how systems behave in production, how they scale, and how they stay maintainable over time. Much of the role involves making architectural decisions, integrating external systems, and building software that can evolve without becoming brittle.
Python Trainer
Taught Python through practical, problem-driven work, covering data wrangling, APIs, automation, and backend development. Much of the focus was on helping learners move from syntax to reasoning about systems and real use cases.
Machine Learning Intern
Worked on applying machine learning and data analysis to financial market data, exploring price movements, trade signals, and portfolio behavior. The focus was on understanding patterns, risk, and diversification rather than chasing predictions.
Python Trainer & Consultant
Worked with developers to build confidence in Python by focusing on real problems and production-style work. Most of the work involved hands-on projects that helped bridge the gap between tutorials and systems used in practice.
