Senior Software Engineer
I build scalable web platforms and cloud-native systems with TypeScript, Python, React, FastAPI, and AWS.
About
I'm a senior software engineer with over five years of experience designing and shipping scalable web platforms and cloud-native systems. I work across the stack — TypeScript, Python, React, Next.js, FastAPI, and Node.js — with deep familiarity in AWS, Firebase, and Google Cloud. I'm happiest at the seam where product features meet the infrastructure that runs them.
Currently, I'm a Senior Software Engineer at xMap, where I helped build the geospatial data marketplace at studio.xmap.ai and the location intelligence platform at polygon.xmap.ai. I led the migration to a serverless architecture (cutting infra costs ~20%), set up a CI/CD pipeline with GitHub Actions that halved deploy time, and shipped a multi-tenant architecture across staging and production.
Previously, I worked at Turing, Simply Zibra, and Decision Labs on mapping tooling, payments infrastructure, and full-stack web apps — building a real-time collaborative annotation tool with deck.gl, integrating banking and payment APIs into a Flutter app on Firebase + GCP, and championing TDD across React, Node.js, and Ruby on Rails modernizations.

Experience
2023 — PRESENT
Senior Software Engineer · xMap
Building the geospatial data marketplace at studio.xmap.ai and the location intelligence platform at polygon.xmap.ai. Led the migration to a serverless architecture, cutting infra costs ~20%, and established a CI/CD pipeline with GitHub Actions that halved deploy time. Integrated Stripe for transaction processing, AWS Cognito with Google Sign-In and multi-factor auth, and a multi-tenant model across staging and production.

2022 — 2023
Software Engineer · Turing
Spearheaded a mapping annotation tool with deck.gl and nebula.gl, including a real-time collaborative editing feature. Optimized application performance by 25% and reduced response time 20%. Integrated GraphQL for efficient data fetching, deployed a microservices architecture, and built automated test frameworks that cut production bugs by 30%.

2019 — 2022
Software Engineer · Simply Zibra & Decision Labs
At Simply Zibra, led development of a Flutter payment app integrating multiple banking and payment APIs, with a Firebase + GCP backend that reduced downtime 15%. Earlier at Decision Labs, modernized legacy apps and shipped full-stack solutions with React, Node.js, and Ruby on Rails — championing TDD, OAuth2/JWT auth, and Redux. Cut deployment times across AWS and GCP by 50%.

Projects
xMap Studio
A geospatial data marketplace where teams can browse, license, and integrate location datasets. I led full-stack development — React, FastAPI, Stripe-driven access provisioning, and AWS infrastructure (Cognito, S3, CloudFront, API Gateway, Lambda).
REACT · FASTAPI · STRIPE · AWS · COGNITO
xMap Polygon
Location intelligence platform with deep geospatial analytics and visualization. I built admin tooling for managing users, datasets, and transactions, plus the data-visualization layer that lets users analyze polygon-level insights.
REACT · DECK.GL · FASTAPI · POSTGIS · EC2
Simply Zibra Payments
A high-performance mobile payment application built in Flutter with a scalable Firebase + GCP backend. Integrated multiple banking and payment APIs for seamless transactions, plus a Stackdriver-based logging and monitoring stack that improved reliability and incident response.
FLUTTER · FIREBASE · GCP · STACKDRIVER · CI/CD
Designed in Figma and built with React, FastAPI, and AWS. Deployed via GitHub Actions. Set in the Inter typeface.
