Software Architecture Jobs

I need a production-ready circuit and compact PCB built around the ESP32-C6 for an IoT device that must run efficiently on both a small solar panel and a rechargeable battery pack. Wi-Fi connectivity is mandatory, and every part of the design has to prioritise ultra-low power consumption so the unit can sit in deep-sleep most of the day yet still wake to trigger a miniature solenoid valve on command. Power architecture The board should accept solar input (≈5-6 V) and seamlessly switch to a lithium cell when sunlight is unavailable. Please integrate an MPPT-style charge controller, battery protection, and a low-loss power-path so the ESP32-C6 always sees a stable 3 V3 rail. Current draw during sleep should stay well under 30 µA.

A single-purpose Discord bot is all that is needed. It should pull a dynamic list of 2000-5000 URLs from a standard Google Sheets document, then—running on a small DigitalOcean droplet—cycle through those links every two to three minutes. For each check the bot must load the page and confirm that expected content is present; if the page renders correctly the bot marks it “Active,” otherwise it flags it “Inactive.” Whenever a status changes, or on every poll if you prefer the simpler approach, the bot must post an individual message for each URL inside a designated Discord channel. Messages can be edited in place or sent anew, so long as they stay easy to read at a glance. Please build with reliability in mind: graceful handling of rate limits, reconne...

Tiny CRM, Lead Automation, and AI SO Setup for Single Hospitality Property LIVE DEMO REQUIRED OF WIP APP BEFORE AWARDING (web for mobile is fine for demo) We run a single hospitality property (book or not, rooms) and are looking for a reliable freelancer to help us put a simple, effective lead management system in place. Right now inquiries come in through different channels and in many different formats. Some are detailed, some are brief, some are forwarded from platforms, some are direct messages. We do not control the format of incoming inquiries, so the system needs to handle real-world messy lead intake rather than a single clean web form. We’d like one clear workflow that helps us respond faster, stay organized, and improve conversions. This is a small project for someone...

$100,000 BUILDER CONTEST — Build a SaaS product that charges Bloomberg Terminal rates while running on pennies. The thesis: Bloomberg charges $28,000 per seat per year. Salesforce charges $300 per seat per month. The APIs underneath them are mostly public. The missing layer was a gateway + AI router that could wire them together. That layer now exists. Our cost per API call is around $0.0001. That means a freelancer or indie founder can launch a micro-SaaS in any vertical (finance, legal, healthcare, real estate, crypto, dispensary, restaurant, HVAC) and charge enterprise rates while running on essentially zero marginal cost. 98% gross margin. What we are looking for in this contest: Build a working app on the MeterCall platform in 25 days. Any vertical. Show a 60-second screen rec...
