We are building a custom internal platform for our travel advisor network. This is not a website or a Webflow project. This is a production-grade full-stack application built in Next.js and TypeScript with MongoDB Atlas as the primary database and Airtable as the CRM and operations layer. The platform includes a role-based advisor dashboard, a super admin dashboard, a custom booking submission form, commission tracking and tier logic, five admin report types with CSV exports, secure invoice file storage, transactional email workflows, and integrations with Airtable, Webflow CMS, Mailgun, Cloudinary, and a private object storage service such as AWS S3 or Cloudflare R2. We have a detailed internal technical proposal covering architecture, phased delivery plan, data models, role and permission structure, milestone definitions, and cost modeling. You will receive the full document before any engagement begins. This is a fixed price milestone based engagement across five phases over approximately eight weeks. All source code, accounts, and assets are owned by Xullu throughout the project. Do not apply with a generic proposal. Your application must include a live production Next.js application you have built, your approach to Airtable API caching for high volume reporting, your approach to secure financial document storage with server side access control, and your fixed price broken down by milestone. Budget range is $10,000 to $14,000. We are not looking for the lowest rate. We are looking for the most qualified.

## Project Overview I am seeking an experienced Senior AI Systems Architect / Full-Stack Engineer to evaluate and potentially lead the technical architecture of a new enterprise software platform currently under development. At this stage, I am not looking for someone to simply write code. I am looking for an experienced technical professional capable of evaluating architecture, recommending technologies, and helping define the engineering roadmap for Version 1. The project involves the integration of artificial intelligence, enterprise software architecture, workflow automation, secure data management, API integrations, and cloud-based application design. Because the project contains proprietary intellectual property, detailed information will not be disclosed during the initial interview process. Candidates selected to move forward will be asked to execute a Non-Disclosure Agreement before reviewing project documentation. ## Initial Objectives • Review the existing project at a high level. • Evaluate technical feasibility. • Recommend the most appropriate technology stack. • Design the production architecture. • Develop an implementation roadmap. • If mutually agreed, continue as the lead software architect for Version 1. ## Required Experience Applicants should have significant experience with: • Enterprise software architecture • Artificial Intelligence integration • API development and integration • Full-stack application development • Cloud architecture and deployment • Database design • Authentication and application security Excellent communication skills are important. I am looking for someone who enjoys solving complex architectural challenges and who is interested in building something from the ground up. ## Please Include 1. A brief summary of your architecture experience. 2. Examples of enterprise software systems you have helped design. 3. AI-related experience. 4. Your preferred technology stack. 5. Why this opportunity interests you. The initial engagement is intended as an architectural evaluation. A longer-term relationship may develop if there is a strong mutual fit.

Senior Full-Stack Developer — WordPress, Web Ops & Workflow Automation Tax Relief Helpers helps individuals and businesses resolve tax debt and IRS issues. Our websites are the front door of our business — they drive our lead generation and run our paid and organic marketing. We're looking for a senior developer to own that web stack end to end and help us tighten the operations behind it. This is a full-time (~40 hrs/week), ongoing, remote role with real autonomy. We want someone who can diagnose problems, propose solutions, and ship them without heavy supervision. WHAT YOU'LL DO Own our WordPress sites (on WP Engine): keep them fast, secure, and up to date — themes, plugins, updates, backups, performance. Build responsive landing pages and site sections that convert visitors into leads, and run A/B tests to improve them. Own conversion tracking and integrations: Google Analytics 4, Google Tag Manager, ad pixels (Google, Meta, Microsoft), call tracking, and form-to-CRM connections. Evaluate our workflows: audit how work moves through our tools, document it, and automate the manual, repetitive steps. Protect the stack: secure forms, SSL, access controls, and reliable backups for sensitive customer data. Support technical SEO: Core Web Vitals, page speed, structured data/schema, clean markup. REQUIRED SKILLS (please only apply if you can show real work in each) 7+ years building and maintaining production WordPress sites — child themes, plugins, PHP, page builders (Elementor and/or Gutenberg). WP Engine a strong plus. Solid HTML5, CSS3, JavaScript (ES6+), PHP, MySQL, and REST APIs. Proven track record building responsive, high-converting landing pages and running A/B tests. Hands-on with GA4, Google Tag Manager, and conversion tracking/pixels for Google, Meta, and Microsoft ads. Experience connecting forms and web apps to CRMs via APIs, webhooks, or Zapier/Make, and scripting automations (JavaScript/Node or Python). Secure handling of sensitive/PII data, SSL, and least-privilege access. Git version control and a disciplined staging-to-production workflow. Technical SEO fundamentals (Yoast familiarity a plus). NICE TO HAVE Experience in lead-generation, financial services, or a tax/legal business. Modern JS framework (React), headless WordPress, or custom API development. Basic DevOps — monitoring, uptime alerts, CDN configuration. HOW TO APPLY In your proposal, please answer these and include links to 2–3 sites you've built or manage (proposals without work samples won't be considered): Which WordPress sites have you built or managed (ideally on WP Engine or similar)? Share links. Describe a manual workflow you automated — what tools did you use, and what was the result? How do you approach conversion tracking and analytics for a lead-gen website? How would you spend your first two weeks auditing our sites and workflows? What's your weekly availability, timezone, and expected rate? Rate: $60-$80/hr depending on experience
