Summary: We are building Sphere Inc., an AI-powered SaaS platform focused on the real estate industry. The product is currently in the MVP stage, and we are looking for a strong full-stack developer who can help us build, refine, and launch the first working version. The platform is designed to help real estate businesses automate daily operations, improve decision-making, and use AI agents to support workflows such as property management, lead handling, deal analysis, document processing, reporting, and business automation. This is not a basic website project. We are building a real SaaS product with a modern frontend, reliable backend, AI-powered workflows, and scalable AWS infrastructure.

Responsibilities: - Build frontend and backend features for the MVP - Design and implement AI-powered workflows and agent features - Connect APIs, databases, authentication, and user roles - Set up or improve AWS infrastructure - Help prioritize features and identify technical risks - Communicate progress clearly and regularly Some Knowledge That Is a Plus: - Real estate CRM, property management, brokerage, acquisitions, or leasing platform experience - AWS Bedrock, LangChain, LangGraph, or vector databases - Multi-tenant SaaS architecture - Stripe or subscription billing - DevOps, Docker, CI/CD, and testing - Analytics dashboards, reporting tools, or document automation The ideal candidate is a reliable full-stack developer who can work independently, understand the product vision, ask smart questions, and help us make practical technical decisions during the MVP stage. We need someone who is comfortable in an early-stage environment and can help turn a clear idea into a working SaaS product for real estate users. Please include: 1. Your GitHub, portfolio, or examples of previous work 2. A brief description of your related SaaS experience 3. Examples of AI agent, AI automation, or LLM-powered products you have built 4. Your AWS experience 5. Any real estate platform, CRM, data, or automation experience 6.

Existing founder is looking for a full stack engineer to be the founding engineer at Socratix, an agentic AI powered data platform for sales teams connecting Zoom, Teams and other communication data together to drive insights and deals.

Ideally, this role becomes full time as part of the founding team presenting to investors later in the year. Must have an understanding and appetite for startups and working in an unstructured environment with a build mentality.

COREX MVP Native-feeling iOS and Android app (using a cross-platform framework like Flutter or React Native) User login and profiles COREX onboarding assessment (goals, experience, injuries) AI-generated 15-minute rotational workouts Exercise library with videos and instructions Workout timer and progress tracking Basic AI chat coach for workout and recovery questions Subscription/payment integration Admin portal to add or update workouts and content Save for Version 2 These are valuable, but they can wait: Camera-based form analysis Wearable integrations Advanced nutrition planning Community features Leaderboards and challenges Franchise/business dashboards Live trainer messaging Upwork budget suggestion UX/UI design App development AI integration Testing App Store and Google Play launch That gives you control over quality and payments. One thing I’d add Rather than describing it as just another fitness app, position COREX as a specialized AI rotational training platform. That’s what makes it stand out. For example: “COREX is an AI-powered rotational fitness platform that delivers personalized 15-minute workouts designed to improve core strength, mobility, stability, athletic performance, and functional movement through our proprietary rotational training methodology.” That description is much more distinctive than “fitness app.” My recommendation If I were helping you build this, I’d focus on creating something impressive enough to demonstrate to investors, gym owners, and potential partners—not every feature you eventually want. A polished MVP that users enjoy is often more valuable than a feature-heavy app that’s unfinished. I also think your app could have a clear advantage if it emphasizes the science of rotational training rather than trying to compete with broad fitness apps. That gives COREX a unique identity from day one. The product and program itself is trademarked and patent pending

We are seeking an experienced, senior-level freelance Healthcare Software Architect to lead a structured discovery session and provide an unbiased, independent cost and timeline estimate for a medical billing/MSO utility MVP. We are an established clinical group with immediate, built-in market demand. We have already established our legal foundation; now, we are validating the tech. A prospective developer has already put together a baseline prototype using a headless, open-source EHR framework and a standard medical clearinghouse API. Before finalizing this partnership, we require an independent, objective peer review of the proposed architecture and resource pricing to ensure our Phase 1 MVP is lean, secure, and commercially viable. Scope of Work & Deliverables The ideal candidate will lead a focused Discovery & Audit Phase consisting of: • Architecture & Scope Review: Review our core workflow requirements (specifically handling unique billing and routing logic) and assess if the proposed headless framework is optimally scoped for a Phase 1 launch. • Infrastructure Cost Validation: Provide an independent, line-item cost projection for a HIPAA-compliant hosting environment assuming a starting pool of 50-100 active clinicians scaling to 1,000. • Labor & Retainer Estimate: Review the prospective developer’s timeline and resource proposal. Give us an honest, market-rate validation of the engineering hours required to move the current prototype into production. • Discovery Session: Lead a 1-hour deep-dive consultation with the founder to review your findings and flag potential technical debt. Required Qualifications • Senior-Level Healthcare Architecture: Proven track record designing, auditing, or deploying production-grade healthcare software. • Deep FHIR Expertise: Direct, hands-on experience working with modern, native FHIR data models and headless clinical engines. • RCM & Clearinghouse Knowledge: Familiarity with revenue cycle management workflows, EDI transactions, and clearinghouse API integrations. • Compliance & Security Fluency: Clear understanding of HIPAA-compliant infrastructure hosting and the execution of Business Associate Agreements (BAAs). • Radical Objectivity: This is a strictly advisory, consultative role. We need an unbiased judge who has no stake in the ongoing development contract. Please start your proposal with the phrase "Sovereign Tech." Briefly summarize your experience with open-source healthcare frameworks and headless EHR architectures.
