We are building a next-generation workflow automation platform that combines deterministic business rules, artificial intelligence, document intelligence, and human review workflows into a single operating system. This is not a traditional CRM project. Our vision is to develop a doctrine-driven platform where business rules serve as the system authority, AI serves as an analytical and drafting layer, and human reviewers serve as the final compliance checkpoint. We are seeking an experienced engineer or engineering partner who can help architect and build the platform from the ground up. Project Objectives The platform will: • Ingest and analyze large volumes of structured and unstructured documents • Extract data from reports, PDFs, and supporting documentation • Apply rule-based workflow logic • Generate AI-assisted recommendations and draft outputs • Maintain complete audit trails and workflow transparency • Route work through human review checkpoints • Support future deployment of local AI infrastructure for privacy and performance Core Architecture The system will be built around four primary layers: 1. Rules Engine * Deterministic business logic * Workflow orchestration * State management * Trigger and escalation logic * Audit tracking 2. AI Layer * Document analysis * Classification * Pattern detection * Summarization * Draft generation * Structured outputs 3. Local Processing Layer * OCR * Document parsing * Data extraction * Vector search * Local inference capabilities * Privacy-first processing 4. Human Review Layer * Quality assurance * Workflow approvals * Compliance review * Exception handling Initial Development Priorities Phase 1 • User authentication • Client record management • Document upload system • OCR and document extraction • Workflow engine • Rule-based status management • Review dashboard Phase 2 • AI-powered document analysis • Automated classification • Recommendation engine • Draft generation workflows • Response parsing Phase 3 • Local AI infrastructure • Vector database integration • Knowledge retrieval system • Multi-agent workflow orchestration • Advanced automation Desired Technical Experience Required • React / Next.js • Node.js, Python, or similar backend framework • PostgreSQL or equivalent relational database • REST APIs • Cloud infrastructure (AWS, Azure, or GCP) • Workflow automation systems • Document processing pipelines Preferred • OpenAI APIs • Anthropic APIs • Retrieval-Augmented Generation (RAG) • LangGraph, LangChain, or similar frameworks • Vector databases • OCR technologies • AI agent architectures • NVIDIA AI ecosystem • Local model deployment What We Are Looking For We are not looking for someone who simply builds forms and dashboards.

OVERVIEW We are a technical advisory firm that partners with VC-backed companies to design, build, and scale their engineering foundations. We embed with our clients as a core part of their technical team, not as outside consultants handing over a document, but as engineers who own the outcome alongside them. Our current client is a VC-backed company operating in the auto logistics space. They're at an exciting and critical stage: they have product-market fit, they have backing, and now they need to build the production infrastructure to match their ambitions. We've been brought in to lead that build, and we're looking for a senior full stack engineer to join us for it. This is a greenfield backend API platform built in TypeScript on Node.js with Express or Fastify, and you'd be involved from the very beginning. That means shaping the architecture, setting the patterns, and building something that will need to handle real production load in a fast-moving, operationally complex industry. The backend we're building needs to be reliable, well-structured, and built to grow. If you want to do meaningful backend work on a greenfield codebase, in a real industry with real complexity, working with a team that has high standards, this is the opportunity. WHAT YOU'LL BE BUILDING A production-grade backend API platform in TypeScript on Node.js, using Express or Fastify. Because we're starting from scratch, the early decisions carry significant weight and you'll be part of making them. API architecture, project structure, middleware conventions, authentication approach, error handling, observability, data access patterns: these are all on the table and we want engineers who have opinions about them informed by experience. Day-to-day you'll be writing and reviewing TypeScript, contributing to architecture and design discussions, collaborating with the team on Slack, and joining at least one Zoom sync per week with the broader team and client stakeholders. WHAT WE'RE LOOKING FOR - 5 to 10 years of professional software engineering experience with a strong backend or full stack background. Specifically: - Fluent in TypeScript with a solid working knowledge of the Node.js runtime, including async patterns, error propagation, and performance characteristics, not just the surface API - Hands-on Express and/or Fastify experience with real APIs built using them, a clear understanding of their trade-offs, and the ability to make informed structural decisions without needing to be guided - A track record of shipping and operating production systems, having been accountable for something running live, having handled production incidents, and thinking seriously about reliability, logging, and failure modes. - Comfort operating in a greenfield environment with some ambiguity, able to ask the right questions, help define what isn't yet defined, and take ownership of outcomes rather than waiting for a fully formed spec. - Strong English communication skills, written and spoken. We're a distributed team, async-first on Slack, and we interface directly with a client whose business is moving fast. Clear communication is as important as clean code US-based strongly preferred with meaningful overlap with US business hours required for team and client collaboration NICE TO HAVE - Cloud infrastructure experience (AWS, GCP, or Azure) - Familiarity with authentication protocols (OAuth 2.0, OIDC) - API versioning strategy experience - CI/CD pipeline experience - Domain familiarity with logistics, fleet management, or supply chain systems is a genuine bonus HOW WE WORK We are a tight team with high standards and low tolerance for vague communication or dropped balls. Slack is our primary channel, async-first with responsiveness expected during working hours. We sync on Zoom at least weekly, more often during active design and planning phases. We use Jira for our ticket management. You'll receive a Microsoft 365 account on hire for SSO access to all internal and client tooling from day one. We don't micromanage. What we do expect is proactive communication, early flagging of blockers, and the kind of ownership that comes naturally to engineers who treat a codebase as something worth getting right, not just getting done. On a greenfield project with a client at a pivotal growth stage, that distinction matters. HIRING PROCESS - Intro call (15 min) - the firm, the client, the project, your background, and your questions - Technical screen (if applicable, via Coderbyte) - Background check - standard criminal background check required for all hires, no exceptions - Offer and onboarding - Microsoft 365 account and full tooling access provisioned before day one HOW TO APPLY We read every proposal that makes a genuine effort. Please include: - A description of a production backend system you've built, including what it did, the scale it operated at, your specific contributions, and what decisions you made that you're proud of or would revisit today - Your honest assessment of your TypeScript and Node.js depth. We value specifics and self-awareness over a list of buzzwords Links to code, whether GitHub, open source contributions, a portfolio, or anything else that shows us how you think and work We work with companies at inflection points and we hold ourselves and the engineers we bring in to a high standard. If this project sounds like the kind of work you want to do, make that clear in your proposal and tell us why this domain, this stage, and this type of build appeals to you specifically.

This project is a continuation of the existing SMOX audit and production readiness review currently in progress. The objective is to continue working with the current auditor and transition from audit findings into implementation planning and execution. Current priorities include: • Review completed audit findings • Verify repository structure and production readiness • Implement 30-Day Smox Pro Trial functionality • Review Stripe Connect subscription management • Review Stripe webhook handling and payment events • Resolve subscription and payment-related issues • Correct booking timeline and client visibility issues • Resolve calendar history and scrolling issues • Improve notification reliability • Address production-impacting defects identified during the audit • Establish a milestone-based implementation roadmap Existing repositories, AWS access, Stripe access, audit documentation, and project assets will be provided as needed. This is not a new application build. The project already exists and is currently deployed. The goal is to continue the audit engagement and execute the highest-priority production readiness improvements identified during the review process.

SHOPIFY CUSTOM APP MIGRATION — LIFT-AND-SHIFT, NO DEVELOPMENT I'm looking for an experienced developer to perform a clean lift-and-shift migration of two existing custom Shopify apps from my current development agency's hosting infrastructure onto hosting that I own and control. This is purely a migration job. No new features, no code changes, no enhancements. The apps work as intended in their current state — I simply need them moved. THE TWO APPS BEING MIGRATED 1. A custom currency recorder app used for dual-currency (KYD / USD) transaction reconciliation in our Shopify store. 2. A custom Shopify POS UI extension that integrates with our in-store loyalty program (Jericommerce). Both apps are currently live and in operational use. They cannot go dark, even briefly, during the migration. WHAT I NEED FROM YOU - Coordinate with my current developers to obtain the source code, environment variables, deployment configurations, and any other materials needed to redeploy the apps on new infrastructure. - Recommend a target hosting environment that makes the most sense long-term for this kind of workload (e.g. Render, Heroku, AWS, DigitalOcean) and explain why. - Stand up the new hosting environment under accounts that I own. - Deploy the apps onto the new hosting in a staging state, run them in parallel with the existing deployment, and confirm they are functioning identically to the current production version. - Confirm with me, in writing, that the migrated apps are fully functional before any cutover takes place. I will not authorize the cutover until you have demonstrated the new deployment works as expected. - Execute the cutover — switching webhook endpoints, DNS, Shopify app URLs, or any other relevant routing — in a way that produces zero downtime or operational disruption. - Verify all Shopify connections (webhooks, OAuth, app proxies, POS UI extension registration, etc.) are correctly wired to the new hosting after cutover. - Document the new deployment so I have a clear record of where each app lives, how it is accessed, how the environment is configured, and how to maintain it going forward. WHAT I AM NOT LOOKING FOR - No new features. - No code refactoring. - No "improvements" to the apps. - No exploratory audit or rebuild. - The apps work. They just need to live somewhere else. If you see something in the codebase you'd genuinely recommend addressing, flag it to me separately — but do not change it as part of this engagement. Migration first, anything else later, only if I ask. WHO YOU'LL BE COORDINATING WITH This migration involves three parties: 1. You (the migration contractor). 2. My current development team (who will provide source code and deployment details). 3. Me (overseeing the engagement and approving the cutover). You will need to be comfortable coordinating with my current developers professionally to obtain what you need from them. The relationship is winding down, but the handover should be cordial and efficient. I will introduce you to them directly once we have an agreed scope and timeline. WHAT I'M LOOKING FOR IN A CONTRACTOR - Strong experience with Shopify custom apps (private apps, public apps, app extensions, POS UI extensions). - Strong experience with cloud hosting and deployment (Render, Heroku, AWS, DigitalOcean, or equivalent). - Experience with zero-downtime migrations and parallel-deployment cutover patterns. - Comfortable working with code you did not write and deploying it without making changes. - Direct, honest communication style. I do not need to be managed or shielded — I just need clear updates and reliable execution. - IP ownership: all deployment configuration, hosting accounts, environment variables, and documentation produced under this engagement belong to me. QUOTE AND PROPOSAL Please provide: - A fixed-price quote for the full migration as described above. - Your recommended hosting environment and rationale. - An estimated timeline from kickoff to cutover. - A brief description of your relevant prior experience (Shopify app migrations, hosting transitions, or similar). - Any clarifying questions you have before quoting. Looking forward to hearing from you.
