Live Application

Parkingateway

A high-concurrency reservation platform engineered for multi-airport infrastructure with decoupled inventory synchronization and payment processing.

ArchitectureDecoupled backend architecture engineered to scale across new airport locations without rewriting core reservation systems.
Inventory EngineTravelers select an airport to compare all available real-time parking inventory, shuttle options, and daily rates.
SynchronizationReal-time inventory synchronization guarantees lot availability is verified and locked at the exact moment of booking.
TransactionsEnd-to-end transparent pricing and secure payment processing with automated reservation confirmation receipts.

Live Application

Photography Portfolio

A gallery-first portfolio and client delivery platform built for a professional photographer with dynamic configuration and protected asset delivery.

Client DeliveryPasscode-protected private albums enable clients to securely access, review, and download high-resolution galleries.
Dynamic ConfigAdministrative configuration layer allows updating hero information, about section, and site details without code redeploys.
Media IngestionDirect image uploads to designated photo albums for straightforward collection management.
PerformanceServer-side rendered architecture providing fast image loading and high-fidelity photography display.

SHEMS

An energy monitoring and telemetry platform built with PostgreSQL and Django, deliberately bypassing the ORM to enforce relational database rigor.

Query DesignDeliberately skips the ORM: hand-written SQL queries parameterized to eliminate SQL injection vulnerabilities.
ACID GuaranteesMulti-step device state updates execute in manual database transactions to ensure data consistency upon partial failures.
Telemetry ModelTracks household power consumption across simulated smart IoT devices and variable tariff schedules.
Academic RigorBuilt for NYU's Principles of Database Systems to showcase low-level relational control and transaction isolation.

NYC Traffic & Emissions Pipeline

A real-time distributed data pipeline that correlates NYC traffic speeds with air quality sensor readings to quantify congestion-driven local emissions.

Stream IngestionStreams multi-source vehicular and sensor feeds into Redpanda (Kafka) for PySpark Structured Streaming consumption.
Spatial JoinsApplies Uber H3 geospatial indexing and 15-minute sliding window joins to correlate traffic speeds with particulate readings.
Medallion LakehousePersists processed telemetry into an Apache Iceberg data lake partitioned by timestamp and H3 hexagonal cell.
ObservabilitySurfaces live borough-level emission metrics through a Trino query engine powering an interactive Grafana dashboard.

Nightwalkers

A safety-focused web application simulating a mobile client, developed for coursework to navigate urban corridors using municipal crime data.

Interface TargetWeb-based application engineered with a simulated mobile layout to fulfill coursework project requirements.
Corridor HeatmapsSynthesizes NYC Open Data with crowdsourced incident reports to render real-time neighborhood safety heatmaps.
Routing EngineCalculates and contrasts standard travel routes with safer alternative paths via OpenRouteService and safety heuristics.
Community SignalsInteractive community forum where resident feedback and votes dynamically update routing safety scores in real time.
