Custom Web Application Development for Groundwater Analysis on AWS Serverless

About the client

A Sweden-based organization specializing in groundwater and sediment research, leveraging digital transformation to simplify scientific analysis and deliver scalable, cloud-based solutions for environmental professionals and researchers.

The Story

The client needed to convert a complex scientific script for groundwater level calculations into a scalable web application. The goal was to deliver fast, accurate results with clear visualizations and downloadable reports while ensuring secure access, cost optimization, and future-ready scalability. FiftyFive was engaged to provide custom cloud engineering and software development services, deploying a team with expertise in Python and AWS serverless technologies.

Challenges

• > Restrict execution of compute services to authenticated users only.

• > Execute computationally heavy groundwater analysis without latency.

• > Prevent API Gateway request timeouts during data retrieval.

• > Optimize cloud resource consumption to avoid idle infrastructure costs.

• > Automate scheduled cleanup of outdated generated reports from storage.

The Solution

• > Developed three interconnected services exposed through Python-based APIs.

• > Deployed scientific computation scripts on AWS Lambda for event-driven execution.

• > Integrated AWS API Gateway for secure, scalable user requests.

• > Implemented authentication to enforce role-based access control.

• > Optimized Lambda code execution paths to eliminate flow breaks and reduce runtime.

• > Configured AWS S3 for report storage and automated deletion using Lambda cron jobs.

• > Adopted serverless architecture patterns to ensure resources are consumed only when triggered, achieving high cost-performance efficiency.

The Outcome

The application now generates groundwater analysis results for any selected area within 2–3 minutes, reducing manual processing from several hours to near real-time. Users can visualize layered sediment polygons, analyze groundwater levels, and download structured reports containing charts, graphs, and data tables. The solution cut idle infrastructure costs by leveraging serverless execution and automated cleanup, ensuring scalability without resource waste. This engagement highlights how FiftyFive’s custom cloud engineering and software development expertise enabled the client to achieve faster insights, improved cost efficiency, and a future-ready digital platform for environmental data analysis.
