xMap Studio
xMap · Senior Software Engineer · May 2023 — Present
Overview
studio.xmap.ai is xMap's flagship hosted platform for exploring proprietary geospatial datasets through interactive maps and dashboards. As one of the senior engineers on the founding team, I own significant slices of the product end-to-end — from frontend visualizations down to the multi-tenant infrastructure that powers them.
The platform launched on a containerized Kubernetes stack that was burning a meaningful chunk of runway. I led the migration to a fully serverless AWS architecture (Lambda, API Gateway, DynamoDB, S3) over the course of two quarters, cutting infrastructure costs by roughly 20% while improving cold-start performance and removing an entire category of on-call pages.
Key Contributions
→
Architected and shipped the serverless rebuild on AWS Lambda + API Gateway + DynamoDB, reducing infra spend by 20% and eliminating Kubernetes ops overhead.
→
Built end-to-end Stripe billing integrated with Cognito for multi-tenant authentication — including subscription lifecycle, usage metering, and self-serve plan changes.
→
Reworked the CI/CD pipeline (GitHub Actions + Terraform) so production deploys went from ~14 minutes to ~7 minutes, with one-click rollbacks and per-PR preview environments.
→
Owned the deck.gl-based map rendering layer — implemented data-driven layer composition, GPU-accelerated heatmaps, and viewport-aware tile loading for datasets with millions of points.
