We’re hiring an extraordinary developer to own and grow our Base44 apps and sales products. around the future of AI discovery 1. Future of AI Discovery Core Demo – https://pull-discovery-core.base44.app/ You’ll evolve https://pull-discovery-core.base44.app/ into a beautiful, fluid, high‑performance, full-functional future of AI discovery demo following our advanced and sophisticated technical blueprint Integrate and orchestrate AI models incorporating LLM's, Search and World Models into a seamless experience with no visible seams between UX and intelligence. Own front‑end performance, responsiveness, and micro‑interactions—animations, transitions, and state changes should feel intentional and “alive,” not bolted on. Implement robust logging and analytics to understand how users explore, where they get stuck, and how the discovery engine can adapt dynamically. 2. Book Sales Engine – Six‑Channel Publishing System The second current Base44 project is a system that operationalizes our comprehensive sales plan across six channels. SEE THE COMPREHENSIVE BOOKSALES PLAN ATTACHMENT UNDERNEATH THIS POSTING You will: Translate a detailed multi‑channel publishing strategy (KDP optimization, physical bookstores via IngramSpark, other digital platforms, libraries, bulk institutional sales, and authority‑engine content marketing) into concrete workflows, tools, and dashboards. Build internal interfaces and automations to: Track metadata, pricing, and promotions across Amazon KDP and other platforms. Monitor campaigns across TikTok, Meta, LinkedIn, YouTube, newsletters, and partnerships. Surface KPIs like BSR, review velocity, ad spend, email growth, library adoptions, and bulk orders in a single, coherent view. Design light internal UIs that make it easy for non‑technical team members to update copy, add titles, trigger campaigns, and view performance without breaking anything. Implement robust, testable integrations between Base44, external APIs, and data sources to keep everything in sync as we scale from 8 to 22+ titles and beyond. Who You Are We’re not looking for a generic “fullstack dev.” We’re looking for an unusual combination of visionary and doer: Creative technologist mindset – You think in systems and interfaces at the same time. You care deeply about how a product feels as well as how it works. Obsessed with execution – You’re disciplined, structured, and relentless about shipping. You break ambiguity into sprints, reduce complexity into tickets, and never let projects stall. Proactive owner – You don’t wait for instructions. You propose better ways to do things, flag risks early, and bring options—not problems—to every conversation. Strong product sense – You can balance ideal UX with realistic constraints and understand when to ship v1 vs. when to invest in polish. Comfortable with complexity – Multi‑channel distribution, layered data flows, and evolving requirements don’t scare you; they energize you. Ideal Skills & Experience You don’t need all of these, but you should recognize yourself in most: 5+ years building production web applications, ideally with a strong front‑end/UI focus. Deep experience with modern web stacks (React/Vue/Svelte or similar) and TypeScript, plus comfort with Node or comparable back‑end runtimes. Strong visual/UI instincts: experience collaborating with designers or owning design yourself for data‑rich interfaces and dashboards. Experience integrating AI/LLM APIs and retrieval systems into real products (RAG flows, multi‑step tool use, chat‑like interfaces, recommendation engines). Experience with analytics and experimentation: event tracking, funnel analysis, A/B testing. Familiarity with publishing, ecommerce, or multi‑channel marketing systems is a plus (KDP, IngramSpark, email platforms, ad platforms, analytics). Prior work in environments like Base44 or other low‑code/agentic platforms is a strong plus, but not required if you learn fast.

I am seeking a senior-tier, independent full-stack developer to architect and finalize a high-performance, mobile-responsive Web App MVP for a proprietary sourcing tool called Reseller Bro. The core conceptual logic and UI wireframes are defined; I need an expert to build a production-ready, ultra-low-latency web interface. This application runs directly inside mobile web browsers (Safari and Chrome) on iOS and Android devices—we are completely bypassing the app stores for this phase. Speed and mobile responsiveness are the highest priorities. The Technical Scope of Work:Live Browser Camera View Layer: Build a seamless, cross-platform HTML5 mobile web camera viewport. The video stream must stay active without causing memory leaks, battery drain, or page lag while rendering real-time UI overlay states. Advanced API Data Pipeline: Integrate the front-end capture with the Gemini Flash API to handle fast visual analysis and text parameter inputs. Payloads must be stripped down to return sub-second, structured JSON results. Cache-First Architecture: Implement local storage database logic. The application must instantly query a local cache data ledger using unique product/tag identifiers before initiating an external API request, minimizing token overhead and latency. Preference Panel (X-Multiplier Profit Manager): Build a comprehensive settings interface allowing users to save custom parameters:Custom Multiplier Targets: Users can select profit thresholds based on multipliers (e.g., 3x, 5x, 10x, 15x). The app must weigh user input prices (via voice or text parameters) against Gemini's market data to trigger a binary "Flip or Skip" decision. Marketplace & Category Toggles: Interactive switches to filter consensus data from target platforms (eBay, Amazon, etc.) and categories (Sneakers, Electronics, Vintage). Digital Sourcing Cart with 1-Click Clipboard Export: Create a lightweight workspace data table where approved "FLIP" items accumulate. Implement a 1-click "Copy to Clipboard" feature that formats the entire daily list into a structured string ready for instant pasting into inventory spreadsheets. Exclusive Creator Intake Funnel: Build a clean, single-page application form featuring 6 custom fields and integrated routing logic to process incoming tracking cookies and custom URL parameters for affiliate tracking. Developer Requirements:Proven track record building high-performance, mobile-first web applications with deep API integrations. Elite mastery of managing low-latency JSON payloads and handling unstable cellular network dropouts gracefully. Deep proficiency with Bubble.io or modern, lightweight JavaScript frameworks that plug seamlessly into scalable cloud databases. Must be a solo freelancer. Agencies will be automatically declined. Milestones & Deliverables (Total: $1,500 Fixed Price):Milestone 1 — Core Capture & API Pipeline ($500): Deliver a functional mobile web camera wrapper that successfully captures images, passes text parameters, and parses structured data back from the Gemini Flash API in under 1.5 seconds. Milestone 2 — Profit Logic & Local Cache Engine ($500): Deliver the fully operational X-Multiplier Profit Manager settings panel. Connect the local data tables to execute the cache-first logic, proving that existing data rows load instantly without executing external API triggers. Ensure complete UI responsiveness across iOS Safari and Android Chrome. Milestone 3 — Creator Funnel, Cart Workflow, & Deployment ($500): Deliver the 1-click clipboard export digital cart and the affiliate intake questionnaire with cookie tracking capability. Conduct a final optimization sweep for speed, assist with production hosting deployment, and provide a 3-day post-launch bug-support window.

I need 1 person. no middleman Generalists and "I can pick up Rails" applicants will not be a fit. If we can't see your projects on github dating back years (temp) you're not serious.

Summary I'm hiring a senior full-stack engineer to lead the build-out and launch of a longevity-medicine platform: B2B formulary ordering for licensed providers, plus a patient prescription and reorder portal, built on Canvas Medical (a programmable, ONC-certified EHR). The design and product logic are set. I need someone who configures the EHR, builds the integrations, finishes the frontend, ships it, and keeps it running. This is not a learn-on-the-job seat. It is a finisher seat.

This is a live EHR with patient data, not a storefront. Frontend competence to finish a web app and connect it to a REST/FHIR API A track record of shipping.

Your monthly availability in hours? Thanks
