Our goal: Turn every missed call into a booked job with smart voice agents, seamless SMS follow-ups, and rock-solid telephony. We're early-stage, fast-moving, and need someone who can own the voice backbone and make it bulletproof. The Challenge Our telephony setup (currently with Telnyx DIDs) has issues — inbound routing, call handling, and reliability problems that are blocking smooth missed-call recovery and voice agent automation. We need an experienced backend engineer to diagnose/fix it or migrate to Twilio (or a hybrid) so we can reliably: Capture missed calls and auto-respond with AI voice agents Enable instant booking via voice or SMS Support outbound reminders/confirmations Scale to hundreds of tradie users with high uptime What You'll Do Fix & Optimize Telnyx Integration: Troubleshoot DID inbound routing, SIP/WebRTC issues, call flows, and reliability. Ensure DIDs work flawlessly for inbound voice. Evaluate & Migrate (if needed): Compare and potentially switch to Twilio Programmable Voice for better ecosystem support, easier AI agent integration, or hybrid setup. Build Voice Automation Core: Inbound/outbound call handling (missed call → voicemail → AI agent → booking) Integrate with AI voice platforms (e.g., Retell AI, Vapi, or custom) Real-time call routing, IVR flows, transcription, and post-call actions (create jobs, send quotes) Backend Development: Node.js/Python (or your strong preference) services, webhooks, databases (likely Supabase/Postgres), API endpoints for the mobile app. Reliability & Compliance: Call recording consent, STT/TTS, error handling, monitoring, and scaling. Collaborate with the founder and mobile team to deliver end-to-end flows that feel magical for tradies. Requirements Strong experience with Twilio or Telnyx (both is a big plus) — Programmable Voice, SIP trunks, DIDs, webhooks, Media Streams. Proven track record building production voice/IVR/AI agent systems (missed call handling, conversational agents, booking flows). Solid backend skills (Node.js, Python, or Go preferred) + experience with real-time systems and webhooks. Familiarity with AI voice tools (Retell, Vapi, Bland, etc.) and telephony best practices. Ability to debug complex call flow issues quickly.

1. Project Overview This project builds a computer vision system that tracks whether a handheld object is inside or outside a user defined region on a person's head in real time. The system observes the user through a webcam, allows the user to define a region on their head once at the start, tracks that region as the user moves, and outputs a binary signal whenever a tracked object is inside or outside the region. The signal is transmitted to an Arduino over USB serial and can be used to control any device, such as turning a flashlight on when the object is in the correct region and off when it leaves. The previous developer completed Milestone 1, which covers webcam capture, frame rate monitoring, multi camera support, and a basic overlay system. The remaining work is organized into five milestones over an estimated nine weeks. 2. System Architecture The system runs as a single Python application on the user's computer. It captures frames from the webcam, runs all computer vision processing, and sends commands to the Arduino over USB serial. The Arduino runs a minimal firmware that reads those commands and switches an output pin accordingly. That output pin can drive any device the client chooses. The processing pipeline has six stages that run on every captured frame. First, the frame is read from the camera and corrected for lens distortion using stored calibration parameters. Second, MediaPipe Face Mesh detects 468 facial landmarks on the user's head. Third, the previously stored region anchor points are reprojected into the current frame using the new landmark positions, which is how the region follows the head as it moves. Fourth, a color based tracker locates the handheld object in the frame. Fifth, the system computes whether the object is inside or outside the region using a point in polygon test. Sixth, the resulting on or off signal is sent over serial. A separate safety supervisor runs alongside the main pipeline. It forces the output signal to off if the face cannot be detected, if the object cannot be tracked, or if the serial connection is lost. This guarantees the output is only on when the system is confident about the object's position This WHAT Im looking to be Completed a simple part of the project: Milestone 1: Camera Setup & Calibration Goal: Set up the camera and calibrate the system for accurate real world distance measurements. Steps: Set up and test the camera for real time video capture. Correct camera distortion using OpenCV and a checkerboard pattern. Calibrate the system using a reference object of known size and adjust dynamically based on the user's inter pupillary distance. Success Criteria: Achieve real world measurements with an accuracy within 5%. Correct camera distortion and dynamically adjust scale during use. I do have existing code that does cover this part:with basic webcam capture, FPS display, multi camera preview and overlay logic It is however missing this:calibration, head anchored region tracking, smoothing, object detection, Kalman filtering, Arduino communication and safety logic are missing.

We are looking for an experienced AI automation developer to build a private executive assistant named Jarvis for a business owner named Vince. Jarvis must operate as a professional, respectful, fast-moving executive assistant. The assistant will communicate with Vince through iMessage, access his Google Calendar, remember important information, send meeting reminders, and maintain local files/data on an office iMac. This is not a basic chatbot. We need a working AI assistant that can hold real conversations, remember context, anticipate needs, and protect Vince’s time. Core Requirements The assistant must: Communicate with Vince through iMessage on macOS. Store all data, memory, and files locally on the office iMac. Access Vince’s personal Google Calendar. Send Vince a message 20 minutes before meetings. Remember meeting times, preferences, important facts, and prior conversations. Use context from previous messages and stored memory. Start conversations professionally with: “Hello Sir. What do you need today sir.” Maintain a direct, respectful, professional tone. Avoid fluff, long explanations, repetition, and unnecessary questions. Understand that Vince has zero tolerance for wasted time. Validate Vince’s instructions and respond with useful answers quickly. Ask onboarding questions at first launch to learn Vince’s occupation, goals, priorities, communication preferences, daily routines, and assistant expectations. Be built in a way that can expand later into email, task management, document handling, and proactive reminders. Important Personality / Communication Rules Jarvis must be designed around Vince’s communication style: Direct. No fluff. No jargon. Lead with the answer. Never ask for information Vince has already provided. Protect his time, brand, relationships, and workflow. Jarvis should function as an executive personal assistant whose purpose is to remember everything so Vince does not have to repeat himself. Technical Scope The developer should be comfortable with: macOS automation. iMessage / Messages.app integration. Google Calendar API. Local file storage and local memory architecture. AI agent frameworks. Cron jobs or scheduler-based reminders. Secure credential handling. Local database or file-based memory. Python, Node.js, or similar automation stack. Optional: BlueBubbles, AppleScript, Shortcuts, SQLite, vector database, local LLM tools, OpenAI API, Claude API, or similar. There is already a macOS/iMessage path available using CLI-based message tooling, but we are open to the developer recommending the best reliable implementation. Existing iMessage automation concepts include sending, reading, and watching message history through macOS Messages.app tooling. Deliverables We need the developer to provide: Working Jarvis assistant installed on the office iMac. iMessage communication with Vince. Google Calendar integration. Automatic 20-minute meeting reminders by text. Local memory system. Local file/data storage structure. First-run onboarding question flow. Prompt/personality system for Jarvis. Basic admin documentation showing how to restart, update, and maintain the assistant. Security notes for credentials, permissions, and local storage. Testing checklist proving iMessage, memory, reminders, and calendar sync work. First-Run Intro Flow Jarvis should text Vince an introductory message and ask important setup questions such as: What is your primary occupation? What are your top business priorities right now? What meetings or events should I always remind you about? Who are your key contacts? What should I never interrupt you for? What should I always notify you about? What tone do you prefer from me? What daily reminders would make your life easier? What are your current goals for the next 30, 60, and 90 days? Ideal Candidate The ideal freelancer has built AI agents, personal assistants, calendar bots, local automation tools, or macOS/iMessage workflows before. We want someone practical who can build a reliable working system, not just create a demo. Please include: Similar AI assistant or automation projects you have built. Your recommended tech stack. How you would connect iMessage. How you would handle local memory. How you would secure calendar credentials. Estimated timeline. What you need from us to start.

About us Nucci HQ is an established coaching and consulting company. We run one-on-one and group coaching programs, a consulting arm, and a real estate division, with an active student community and a fast-growing content presence on YouTube and social. We move quickly, and we are investing heavily in AI to make every part of the business faster — and we are looking for the person who will build and own that. The role We are hiring a contract AI Agent & Automation Engineer to design, build, fix, and maintain the AI agents and automations that run across our business — sales, operations, finance, coaching, and content. You will work directly with our founder, Anthony, ship quickly, and see the impact of your work right away. There is a clear roadmap of work ready from day one: stabilizing automations we have already built, standing up an internal command-center dashboard, and shipping a library of single-purpose agents. This is a contract role billed hourly — a flexible, low-friction way for both of us to start, with room to grow as the work does. What you’ll do • Fix and stabilize existing automations so they run reliably. • Build an internal CEO dashboard that pulls sales, consulting, finance, real estate, and social metrics into a single source of truth. • Build workflow automations — meeting note-taking from call transcripts, a speed-to-lead responder, coaching-call tracking, and weekly accountability recaps. • Build a library of single-purpose AI agents across sales, operations, finance, and content — each with one clear job. • Connect agents to the tools we already run on — Slack, Google Workspace, Whop, Heartbeat, ManyChat, Granola, and Fathom. • Prototype new ideas quickly, then harden the ones that work into reliable, monitored systems. • Document what you build so the team can use it and trust it. What we’re looking for • Two or more years building software, with hands-on experience building LLM-powered apps or agents. • Strong Python and/or JavaScript / TypeScript. • Practical experience with LLM APIs (Anthropic, OpenAI, or similar) — prompt design, tool / function calling, and retrieval (RAG). • Strong, hands-on experience with n8n, webhooks, and APIs — building, connecting, and debugging integrations. This is essential. • Comfortable reviving or debugging automations that someone else started. • Good judgment about when an agent is reliable enough to ship — and how to test for it. • A clear communicator who is self-directed and comfortable owning projects end to end. Nice to have • Experience with agent frameworks and orchestration (LangChain, LlamaIndex, MCP, CrewAI, or similar). • Familiarity with our stack — Slack, Whop, Heartbeat, ManyChat, Granola, or Fathom. • Front-end skills for building dashboards and internal tools. • Experience deploying and monitoring production AI systems. • A portfolio, GitHub, or side projects we can look at. Details Location: Fully remote. Type: Contract, billed hourly. Rate: $70–$110 per hour, depending on experience. Hours: Flexible — we will agree on a weekly range based on your availability. Start date: As soon as possible. How to apply Send a short note about a recent AI agent or automation you built and what it does, your resume or LinkedIn, and links to any code, demos, or projects. No long cover letter needed — we care most about what you have built.
