Senior Full Stack Developer – Python, React & AWS | SaaS Development

## Project Overview Solenith Technologies is seeking an experienced Senior Full-Stack Software Engineer to assess our existing AI-powered health and wellness application, InnergyFuel, and help transition it from an MVP to a production-ready Free Tier. The application already has several developed features. We are not looking to rebuild it from scratch but need an experienced engineer to evaluate the current codebase, identify remaining development requirements, and provide a realistic timeline and estimated hours to launch. ## Phase 1: MVP Assessment & Planning The selected engineer will: - Participate in a demonstration and walkthrough of the existing application. - Review the current codebase, architecture, database, and integrations. - Evaluate completed features and identify functionality still requiring development. - Determine the minimum requirements for launching a functional Free Tier. - Identify technical issues, security concerns, and production-readiness gaps. - Provide a detailed breakdown of remaining development tasks, estimated hours, and recommended priorities. - Develop a realistic roadmap and timeline for production launch. **Required Deliverable:** A written technical assessment, prioritized feature list, estimated development hours, and recommended launch roadmap. ## Phase 2: Development & Production Launch Following approval of the assessment, the engineer may be engaged to: - Complete remaining Free Tier features. - Resolve bugs and improve application performance. - Implement necessary frontend and backend enhancements. - Support testing, integration, and production deployment. - Ensure the application is secure, stable, and ready for real users. ## Phase 3: Future Development After the Free Tier launches, we plan to discuss additional features, paid subscription tiers, AI enhancements, and ongoing improvements while the application operates in production. Future work will be scoped and approved separately. ## Required Technical Skills - React, JavaScript, Vite, Tailwind CSS - Python, AWS Lambda, API Gateway - MySQL / Amazon RDS - AWS Cognito, S3, SQS, EventBridge - Amazon Bedrock / AI integrations - REST APIs and GitHub - SaaS architecture and production deployment Experience with Stripe, Terraform, and CI/CD is a plus. ## Ideal Candidate We are looking for someone who: - Has 7+ years of software engineering experience. - Has successfully taken SaaS MVPs into production. - Can assess and improve an existing codebase. - Can provide accurate development estimates and timelines. - Understands scalable, secure cloud applications. - Communicates clearly and works independently. ## Engagement & Budget This project will begin with a **paid, fixed-scope MVP assessment**.
