About the app: StoreRead is a video storytelling app for families and communities to record and preserve spoken memories and life stories. It's live on the App Store and has been tested in-house. We now want honest feedback from a first-time outside user — can a non-technical person succeed at the core flow, and does it feel good to use? Location: US-based testers only. What you'll do: - Use the app as a real first-time user and work through the guided tasks we provide. - Try the core flow end to end: record/upload a video, look at the auto-generated transcript, play it back, search, organize into topics, and share (including opening a shared link). - Share honest impressions as a non-technical adult — what was easy, what was confusing, and anything that felt slow, unclear, or broken. About the videos you'll upload: You'll record and upload two of your own test videos to exercise the flow — please include at least one longer video close to the 20-minute maximum StoreRead supports, plus a short clip. Content can be anything low-stakes (talk about your day, describe a hobby, read aloud). Pay attention to upload time, transcription, and playback on the long video especially. Uploads are private by default and deletable. What we're looking for (deliverables): 1. Work through the guided tasks as a first-time user. 2. Upload two of your own test videos (one short, one close to the 20-minute max) and note how upload, transcription, and playback went. 3. Fill in our simple feedback form as you go — for each task it just asks: did it work as you expected, how easy was it (a 1–5 rating), where you hesitated or got confused, whether anything broke, and any other comments. Short, honest notes are perfect. 4. A few sentences of overall impressions: your biggest point of confusion, what a non-technical person would struggle with, your favorite thing, and whether you'd recommend it. 5. Optional but appreciated: a quick screenshot or screen recording for anything that was confusing or broke (no formal bug reports required). Devices: - Real devices only (no simulators). - iPhone primary (iOS 17+); iPad secondary if you have one. We provide: - App Store download link, a test account, and sample content. - A guided task list and a simple feedback form (mostly short questions and 1–5 ratings). Requirements: - Comfortable using iPhone apps day-to-day and writing clear, honest feedback. - Attention to detail and the patience to notice what's confusing. - Formal QA experience is NOT required — we specifically want a genuine first-time-user perspective. Consumer-app or usability-feedback experience is a plus, not a must. Compensation & duration: - Hourly: $30/hour, up to a 4-hour maximum (about $120 total). - Expected effort roughly 2–4 hours over 5–7 days. - Tracked through Upwork's hourly system (Work Diary); we'll set a 4-hour weekly limit so the total is capped.

We are migrating an existing, field-proven embedded firmware codebase from its current microcontroller onto a new PCB design built around an STM32F4-series MCU(STM32F417, Cortex-M4F, LQFP-100). The firmware controls precision sensing and closed-loop valve/actuator drive on the instrument. The codebase exists and works today; this is a port and bring-up effort, not a clean-sheet design.

I need the text updated on an existing badge/graphic on my website's homepage. I have the SVG source files ready to share for both desktop and mobile versions. What needs to change: Replace "Transparent Pricing" with "LLC & Insured". Matching the existing font, size, and style exactly (I don't have access to the original font file, so you'll need to match it visually from the current design). What I'll Provide: SVG files for both desktop and mobile versions, Screenshot/reference of the current live badge for exact style matching Scope: Edit text only. No redesign, layout, or other changes needed Should be a quick turnaround for someone comfortable with SVG editing

I am looking for a paparazzi- I am attempting to find myself; but as someone who’s always observing others I need an outlet that allows for me to observe myself from the outside looking in. I am also looking to be apart of the entertainment industries (music, fashion, business) and with that comes stares from strangers - I want to ensure I’m showing my best self and be sure that I am aware of who that is in all phases of my life. And I want to be able to show that display to others.

Scope of work (fixed) 1. Firebase setup — create/configure the project under my firm-owned account, enable Authentication and Firestore. 2. Database structure — create the collections per my spec: users (first name, last name, email, phone, consent, A-number, language, created date), a recipients subcollection, and an alerts collection. 3. Security rules — users can read/write only their own data; alerts written via Cloud Function only. Data minimization matters (see note below). 4. Wire the existing registration screen to save name / phone / email to users on submit (consent-based; the screen and consent UI already exist). 5. In-app account deletion — delete the user's Firestore data + Auth record (Apple requires this). 6. SOS engine — a Firebase Cloud Function that sends SMS via Twilio when SOS is pressed: text each saved recipient + notify the firm, include the user's captured GPS location as a map link, and log an alerts record. Wire the app's existing "Alert my people" button to call it and pass location. 7. Leads dashboard — a simple authenticated web page listing registered users (first name, last name, email, phone, sign-up date) with CSV export. List + export only; no CRM features needed. Out of scope: any UI/screen design, navigation, or content — all done. Encounter audio/video recording (v2). Android (later). What I provide • The finished FlutterFlow project (I'll grant access) • A detailed build spec (data model, cloud function outline, permissions, App Store requirements) • All content and branding • My Apple Developer + Firebase accounts (firm-owned)Required experience • Firebase: Firestore, Auth, Cloud Functions, security rules • Cloud Functions calling Twilio for SMS — this is the critical skill • Integrating a backend into an existing FlutterFlow project • Understanding of iOS constraints around messaging (see note) Critical technical note (please address in your proposal) Please confirm you understand that iOS cannot send SMS silently in the background, so the SOS messaging must be dispatched server-side (Cloud Function → Twilio), not from the app directly. Proposals that describe the app texting contacts directly will not be considered. About the users (please read) Users are often undocumented or mixed-status people. Data minimization, encryption, and transparent consent are requirements, not options. No covert or undisclosed data collection. I need someone who takes this seriously. To apply, include 1. Links to 1–2 apps where you integrated Firebase/Twilio (App Store links if possible) 2. A brief description of a Cloud Function you wrote that called an external API (Twilio or similar) 3. Your fixed-price quote and timeline for the scope above 4. Any questions about the spec

Project Overview We're building out a new ecommerce homepage on Shopify. We're currently planning to use the Mila theme, but we're not married to it — if you have a strong reason to recommend a different base theme (better fit for the design, more reliable section architecture, better long-term maintainability, etc.), we're open to hearing that in your proposal. Full mobile and desktop designs are provided (attached) and need to be implemented as close to the designs as possible, using the theme's native sections/customizer wherever feasible, with custom sections/liquid where the theme doesn't already support what's shown. This is the first phase of a larger site build — we're starting with the homepage to establish the pattern for how we'll work together before handing off additional pages (collection, product, etc.). What's Provided Full homepage design (attached image/Figma — confirm which you'll receive) Brand assets: logo, fonts, color palette (to be shared on hire) Existing Shopify store with Mila trial theme installed An detailed overview of the sections will be provided on the kickoff call Technical Requirements Build using the chosen theme's built-in sections, blocks, and theme editor settings wherever possible — do not fork into a fully custom theme unless a section genuinely can't be achieved with the theme's architecture Every section must be theme-editor-configurable — this is a hard requirement regardless of which theme is used. No hardcoded content; we need to be able to edit text, images, and links ourselves after handoff without touching code Fully responsive across desktop and mobile — please confirm mobile breakpoints match (or reasonably adapt) the desktop design Cross-browser tested (Chrome, Safari, Firefox, Edge) Optimized images/lazy loading — no page speed regressions. Optimized images will be provided. Basic accessibility: proper alt text fields, semantic heading structure, keyboard-navigable menus Clean, commented Liquid/CSS/JS — no leftover unused code from the base theme Open Questions for Freelancer (please address in your proposal) Do you have experience with the Mila theme? If you'd recommend a different theme for this design, tell us why and what it would change about cost/timeline If we do use Mila, are you comfortable extending it with fully theme-editor-configurable custom sections where needed? Will all content (product grids, testimonials, sale badges, stats) be dynamic/theme-editor-driven, or should any sections be static/hardcoded for now? Will you be able to integrate the third party plugins required here (Yotpo reviews specifically)? What's your estimated timeline for the homepage build? Do you provide a staging/preview link for review before pushing live, and how many rounds of revisions are included in your quote? Can you flag anything in the attached design that may need clarification (icon behavior, hover states, mobile stacking order) before starting? Deliverables Fully built, responsive homepage live on the Mila theme or other theme in a development/unpublished format, ready for review

Partiful (the events platform) is hiring a freelance QA professional to audit the Spanish-language version of our mobile app. The work - two sessions: Session 1: full review of the Spanish app on both iOS and Android - translation accuracy in context, flagging awkward or broken copy, proposing tighter phrasing where strings run long. Deliverable: clear, written, reproducible bug reports. Session 2 (a few weeks later): re-verify after our fixes ship. Strong work may expand scope (web + notification strings) and can lead to recurring per-release Spanish QA. Requirements: Professional QA experience - mobile app testing, with reproducible written bug reports Native US/Latin American Spanish (our app ships es-US - not Spain Spanish) Able to test on both iOS and Android devices Remote welcome (US/LatAm time zones); NYC or LA a plus Preferred: you already know Partiful as a user - context matters for judging copy Process: Short intro call → paid 2-hour trial task (audit one section of the app, deliver a bug report) → full engagement. Approximately 25–40 hours total across both sessions.

Figma UI/UX polish for 2-screen mobile prototype (iOS) Need a Figma designer to quickly clean up and finalize a simple 2-screen prototype for a popular voting mobile app (QED). Screen 1: Bill voting card (Yea / Nay / Abstain, Up / Down / Skip options). Screen 2: Live results summary screen. I already have the wireframes sketched in Figma and the Apple iOS 27 UI Kit attached to the draft file. You will just need to convert my rough sketches into clean, standard iOS components so I can shelf the visual design.
