    I’m revamping a web product that relies on intelligent, self-orchestrating workflows. The stack must be built end-to-end—interface, APIs, and infrastructure—while weaving in three core AI enablers: Claude code, GPT Codex, and a deeply Agentic development approach. The heart of the assignment is process automation: think hands-free data ingestion, decision logic that evolves with new prompts, and autonomous agents that hand off tasks to one another without human nudging. I already have the big-picture user stories and a loose wireframe; what’s missing is a robust full-stack implementation that transforms those ideas into a production-ready, scalable platform. Key deliverables • Architecture proposal detailing how each agent will call Claude code and GPT Co...

    I’m building a full-stack web platform that sells access to an in-house large-language-model (LLM). The site’s core is e-commerce, but instead of one-off product sales I need subscription services with clear, tiered plans (think “Starter”, “Pro”, “Enterprise”). Each tier will unlock a different usage quota to the model, so the paywall must integrate tightly with the API gateway that fronts the LLM. Scope of work • Design a responsive customer-facing site where visitors can learn about the model, compare tiers, and sign up. • Implement secure user authentication, payment processing, and a dashboard where subscribers can view remaining tokens, upgrade/downgrade, or cancel. • Build the back-end that meters requests to the L...

    I’m ready to launch a new venture whose entire value proposition is anchored on one person’s standout skill. If you are already operating at a mastery level—whether that is in software development, digital marketing, graphic design, or another niche you can prove superior in—I want to wrap an entire business model around what you do best. We will work in a hybrid style: some sessions will be face-to-face for deep-dive strategy and creative sprints, while day-to-day execution can remain remote. Timing is critical; I’d like to move from first conversation to a validated proof of concept as quickly as humanly possible. What I need from you right away • A concise presentation that demonstrates your signature skill and how it can translate into a scal...

    I need a responsive web application built around a Unilevel-based MLM model. The first priority is a rock-solid user registration and account-management module: new sign-ups should flow smoothly, profiles must be editable, and every action has to be logged for compliance. The commission engine follows a classic Unilevel structure. Each customer will be able to refer others, accrue commissions on their direct and indirect sales according to configurable percentage tiers, and view their running totals in real time. The logic must be transparent and easy for me to adjust later from the database or an admin panel. For now, the only active role in the system is Customer, yet the architecture should leave room to introduce Admin and Distributor levels without major refactoring. Clean role-...
