Real-Time Data Processing: Developed backend services and web scrapers handling large datasets, incorporating real-time updates over WebSockets and GraphQL subscriptions.
Key skills
Professional experience
Managed backend engineering for core educational products, overseeing the development and maintenance of distributed services using Go, Python, GraphQL, gRPC, and Neo4j. Directed the integration of event-driven architectures with Redis, NATS, and Kafka within Kubernetes environments, while maintaining system observability through Prometheus and Grafana.
- Rebuilt the core computation engine as a Python and NumPy gRPC service, profiling computation and memory to locate bottlenecks and cutting API response time from 5-10 seconds to under 2 seconds.
- Built the Go backend for AI-generated lesson plans using reusable interfaces, replacing goroutine-based generation with NATS consumers so long-running generation could recover across service restarts.
- Replaced repeated polling with event-driven updates over GraphQL subscriptions and NATS, pushing student state changes to the teacher UI as they occurred.
- Optimized nested GraphQL data fetching with DataLoader batching and caching, addressing N+1 patterns that could issue hundreds of individual database queries per request.
- Implemented the Redpanda and Kafka to NATS migration for event-driven services, designing subjects and consumers on JetStream and KV while cutting publishers over to NATS.
Designed backend systems for early-stage products, focusing on independent API design, user management, and database operations.
- Built the Go backend for a business operations platform and a sports training application, managing REST API design, user management, and SQL database operations.
- Added real-time and search capability to services by pushing live dashboard updates over WebSockets and backing search with Elasticsearch.
Developed automation scripts and web scrapers, managing client specifications for data extraction and cloud storage delivery.
- Built web scrapers and browser automation scripts using BeautifulSoup, Selenium, and Puppeteer to extract target site data according to client requirements.
- Processed extraction jobs covering 1 million e-commerce records with associated images and property details.
- Cleaned datasets using Pandas and delivered results through Amazon S3, GCP buckets, and email for one-time and recurring jobs.
