High-Performance eCommerce Platform

Scalable storefront and checkout built to survive peak sale-day traffic

A production eCommerce platform where the previous storefront degraded under promotional traffic spikes, and slow page loads were bleeding checkout conversion. Rebuilt the rendering and data layer so performance held under load instead of failing at the exact moment revenue was highest.

Peak concurrent sessions: 10k+
Page load (p75): <1.2s
Uptime on sale days: 100%

AI Product Recommendation Engine

Personalized recommendations without a personalization latency tax

Static best-seller lists on product pages were leaving conversion on the table. Built a recommendation service that personalizes results per shopper while keeping response times indistinguishable from a static list.

P95 response time: <80ms
Cold-start coverage: 100%
Recompute cadence: Nightly + real-time

Job Search Engine

Candidate-to-employer matching with real-time messaging at scale

A job discovery and application platform matching candidates to postings and enabling direct, real-time conversations between employers and candidates — built and operated as a long-running production system, not a prototype.

Relevance scoring: Multi-signal
Messaging: Real-time, horizontally scaled
In production: 2.5+ years

Artist Management Platform

Bookings, royalties, and contracts in one system of record

Music labels and artist managers were tracking bookings, royalty splits, and contracts across spreadsheets and email — a setup that produced missed payments and double-booked dates. Built a multi-tenant platform to replace it.

Tenant isolation: Query-layer enforced
Royalty calc: Rules-engine driven
Roles supported: Admin / Agent / Artist

Event Management Platform

Ticketing and live check-in for high-traffic events

Paper ticket lists and manual check-in created long entry lines and gave organizers no real-time visibility into attendance. Built a ticketing and check-in system designed for spotty connectivity at the door and zero tolerance for duplicate entries.

Ticket validation: Offline-tolerant
Check-in visibility: Real-time
Duplicate entries: Zero, by design

Magic Mirror AI / AR Platform

Interactive AI/AR kiosk experience for retail and event activations

An interactive kiosk product combining real-time computer vision with AR overlays, built for retail and event brand activations that needed to stand out with a hands-on, camera-driven experience rather than a static display.

Detection pipeline: Real-time, tuned per-device
Frame rate: Stable under kiosk constraints

Multiple Enterprise SaaS Applications

A shared platform foundation reused across concurrent client engagements

Enterprise clients across different industries needed bespoke internal tools and customer-facing SaaS products. Rather than rebuilding auth, billing, and access control per engagement, built a reusable service foundation each project forks and extends.

Concurrent engagements enabled: Multiple
Shared foundation: Auth · RBAC · Billing · Notifications
