Software Developer (AWS / Python / JavaScript)
7 Shot Tennis, LLC is a two-man startup company based in Norfolk/Virginia Beach, VA. The Company’s primary service is the analysis of characteristics of point-ending shots of video-recorded tennis matches in order to identify individual players’ strengths, weaknesses and tendencies, for the benefit of tennis players, coaches and instructors. Toward that end, the Company has developed (1) a web-based app that is used to collect, compile, sort and display user-filterable attributes pertaining to every point of a selected tennis match, and (2) a web-based app (associated with the previously mentioned app) that is used to timestamp and synchronize video clips of each corresponding point of the match. To date, these apps have been successfully used to analyze several hundred tennis matches at all levels of the game. Current users of the company's services include men's and women's nationally ranked college tennis programs. It is the maintenance and continued enhancement of these two apps for which the Company is currently seeking a reliable part-time software developer / consultant. The Company’s principals were the founders and creators of the Universal Tennis Rating (UTR®) system that currently is the most widely recognized and most reliable tennis player rating system in the world.

We are seeking a part-time consultant to help maintain and evolve a production serverless web application built entirely on AWS. This role is ideal for someone who enjoys clean architectures, lightweight systems, and full-stack ownership within a modern serverless environment. This application is a production-grade, serverless web platform built entirely on AWS. It follows a distributed architecture pattern where frontend applications communicate with backend services through API Gateway, with all business logic handled via AWS Lambda functions and data persisted in DynamoDB. Architecture Overview
- Frontend Layer: Built with HTML, CSS, and JavaScript; hosted via AWS Amplify; communicates with backend services through API Gateway.
- API & Integration Layer: API Gateway routes all frontend requests; each endpoint triggers a corresponding Lambda function; business logic handled in Lambda.
- Compute Layer: 50+ AWS Lambda functions written in Python handling processing, business rules, integrations, validation, and orchestration.
- Data Layer: 10+ DynamoDB tables designed for partition-key–based access patterns with GSIs for optimized querying.
System Scale & Complexity
- 50+ Lambda functions
- 10+ DynamoDB tables
- 25,000+ lines of application code
- Fully serverless architecture
- No traditional server infrastructure
Architectural Characteristics
- Event-driven architecture
- Stateless computer model
- Horizontally scalable
- Fully managed AWS infrastructure
- CloudWatch-based observability
- IAM-secured service boundaries
Codebase Status The system consists of approximately 25,000+ lines of modular application code. The codebase is not currently hosted in GitHub and is shared via secure zip distribution. Frontend and backend components are clearly separated across Lambda services. Operational Profile
- Cross-service debugging capability required
- Understanding of serverless request lifecycle
- DynamoDB data modeling experience
- Familiarity with AWS IAM, Amplify, and API Gateway
- Distributed system operations rather than monolithic deployment
