I’m launching an online school and need a complete platform—both a responsive website and a companion mobile app—that lets me teach live video classes. The classroom experience must include an interactive whiteboard, screen-sharing capability, and a live Q&A chat so I can engage with students in real time. Students have to be able to create an account, verify their email or phone, and sign in securely before joining a session. From there they should see upcoming classes, enter the live room at the scheduled time, and interact with the tools mentioned above. Deliverables • Website front-end and back-end ready for production • iOS and Android app built from the same codebase or native, as you prefer • Secure user registration and authentication flow • Real-time video classroom with interactive whiteboard, screen sharing, and chat integrated seamlessly I’m open to your preferred tech stack—whether that’s React, Flutter, Node.js, WebRTC, or similar—as long as it can reliably support low-latency live streaming and the whiteboard features. Please outline your approach, any similar projects you’ve completed, and a projected timeline in your proposal.

We have created a backend part of our system and vibed out the frontend. Basing on this and on a new design of the user interface we will want to re-develop the frontend part of our application. Assume 1 month full time development for price estimation.

Reading original files with OCR precision, preserving the exact layout and fonts. Editing data within the file. Saving the work to PDF files while maintaining the exact appearance, parameters, and metadata of the original files. File behavior must be identical to the original—text must be clickable and copyable, not an image, etc.

We are building a real-time in-car fuel cost tracker that plugs into any vehicle's OBD-II port. The device uses an M5Stack Core2 microcontroller to read engine data via CAN bus, calculate live trip costs in EUR (like a taxi meter), and track CO2 emissions—all without draining the car battery. It automatically logs trips, maintains a multi-year history, and exports data to microSD as CSV for tax or fleet analysis. The prototype must survive automotive thermal extremes, power loss, and frequent starts/stops. This is market validation for a consumer product targeting the 95% of drivers who want real cost visibility but won't install complex diagnostics. Success is measured by accuracy within 10% after one calibration fill-up, zero data loss through 50 abrupt power cuts, and deep sleep at 2 mA or less.

Project Description: I need to develop a simple embedded fuel cost calculator on Arduino. This is a basic device that tracks trip expenses based on fuel consumption, NOT a complex system. Requirements: Hardware: Arduino Nano or similar microcontroller 16x2 LCD display 3 pushbuttons: START, STOP, and RESET Simple plastic enclosure 12V power supply (car cigarette lighter or battery) Functionality: Initial Setup: Upon startup, select vehicle type (dropdown menu on LCD) or manually enter fuel cost per km (example: 0.10€/km) Trip Mode: Press START button to begin tracking LCD displays real-time distance traveled in km Trip is recorded every 1 second or per kilometer Trip End: Press STOP button to end trip LCD displays: total distance (km), total cost (€), cost per km Memory: Keep last trip data displayed until next START RESET button clears all data and restarts Input Data: Distance sensor (wheel rotation sensor via odometerOBD2 data or GPS if simpler) Manual entry of fuel cost via keypad (€/km) Output: LCD shows: distance, cost per km, total trip cost Simple, readable display (no graphics needed) Nice to Have (Not Required): Small buzzer for START/STOP confirmation Data storage of last 5 trips Toggle between € and $ currency Budget: Maximum 150€ for parts + labor Delivery: 2-3 weeks Quantity: 1 prototype

Zlecę stworzenie skryptu, który przez oficjalne API Allegro będzie codziennie wyszukiwał popularne, ale wyprzedane/zamknięte oferty w wybranych przeze mnie kategoriach. Działanie bota: Pobiera listę aktywnych ofert ze wskazanych kategorii i zapisuje w bazie te z wysoką sprzedażą (np. >50 sztuk). Przy kolejnym skanie sprawdza ich status. Jeśli oferta została zamknięta lub stan spadł do 0, skrypt to wychwytuje. Generuje codzienny raport (Excel/CSV) z listą tych produktów. W raporcie potrzebuję: Nazwa przedmiotu, Kategoria, Kod EAN (GTIN), Cena oraz liczba sprzedanych sztuk przed zamknięciem. Proszę o podanie ceny, czasu realizacji oraz informacji o doświadczeniu z API Allegro.

We are publishing an audiobook of a Polish children's travel book (9 chapters, ~70 min of mastered audio with music). A warm story of a young girl who, thanks to a magical find, travels across the world: the Mexican jungle and Mayan pyramids, the Himalayas, the Trans-Siberian Railway and Lake Baikal, a Turkish bazaar, the Mongolian steppe. Watercolor illustrations. We are looking for a freelancer to turn it into ONE FULL-LENGTH VIDEO (~70 min) for YouTube — the whole book in a single film. CONCEPT (we have a working proof-of-concept): - top-down shot: the book on a wooden table (compass, map, toy plane); a woman's hand opens the book and turns pages in rhythm with the narration; - the pages show the REAL spreads of the book (we provide 300 DPI renders) — legible text and illustrations; - the "magic" effect: every now and then an illustration comes alive for a few seconds (wind in the hair, a flying bird, a glimmering crystal), then returns to a still page; the watercolor style MUST be preserved (no photorealism); - everything synced with the audio (we provide word-level narration timestamps). WE PROVIDE: audio of all 9 chapters (MP3), 300 DPI page renders (PNG), 28 hi-res illustrations, timestamps (JSON), our test clip as a reference, full commercial rights. TECHNIQUE: your choice — AI video (Kling/Veo/Runway), After Effects 2.5D, or a combination. What matters: a natural hand, a locked-off camera, legible pages, charming "come-alive" moments. STAGES: 1) PILOT — chapter 1 (~13 min) to approve the style; 2) after approval — the full ~70 min film assembled into one video (smooth transitions, an intro with the book opening, an ending with it closing). IN YOUR OFFER: portfolio (illustration animation / storybook / AI video), your technique and ideas for the "come-alive" moments, a price for the pilot and the full film, a realistic pilot deadline (preferably within 3 weeks). Communication in Polish or English.
