Infrastructure Investment Platform

Nuxt.js GraphQL PostgreSQL AWS Lambda API Gateway CircleCI

−30%API response time

Overview

Infrastructure investors needed a single platform to manage loans, track performance and surface live analytics without engineering involvement. I built the full stack — a serverless GraphQL backend and a Nuxt frontend with a self-service CMS and real-time dashboards.

The Challenge

Investment teams relied on manual spreadsheets and developer hand-offs to update performance figures, creating latency and risk in a domain where data accuracy is critical.

Approach

Designed a serverless GraphQL API on AWS Lambda + API Gateway, improving response times by ~30%.
Built interactive performance dashboards with real-time investment analytics.
Delivered a CMS so non-technical staff could manage content and figures directly.
Established a CI/CD pipeline with Jest and CircleCI for automated, confident releases.

Architecture

FrontendNuxt.js (Vue 3) with Vuex state management

APIGraphQL served from AWS Lambda + API Gateway

DatabasePostgreSQL with optimised relational schema
