Custom Cryptocurrency ASIC mining Chip

I’m looking for an experienced ASIC engineer or hardware consultant to help develop a custom low-power ASIC chip designed to mine the Kaspa cryptocurrency, which uses the kHeavyHash algorithm. The goal is to create a compact, USB-powered miner (similar in concept to Bitaxe for Bitcoin), intended for hobbyists and solo miners. The project will be fully open-source, and we are building both the ASIC and supporting control board (likely with an ESP32 or STM32 microcontroller). I’m a non-technical founder leading this initiative, and I need someone who can: • Advise on or create the ASIC design (based on the open kHeavyHash spec) • Suggest or manage FPGA prototyping (if needed) • Prepare the design for low-volume fabrication (ideally <5W–50W power budget) • Work with or provide input for PCB/control board integration The ideal candidate will have experience with: • Crypto mining ASICs (Bitcoin, Ethereum, or altcoin mining chips) • FPGA-to-ASIC transitions (helpful but not required) • Low-power chip design and Stratum/miner protocol integration This is an exciting opportunity to help launch the first open-source Kaspa ASIC miner, and potentially contribute long-term as the project scales.

Development of an AI-Powered Web Application for a Running Shoe

This project aims to develop an innovative web application to market a customizable running shoe. The app will utilize computer vision, machine learning, and adaptive questionnaires to determine each user's optimal shoe size and gait characteristics. A foot scanner using the front-facing camera will measure foot dimensions to ensure proper fit. Users will also complete an intelligent health survey and upload a short video of their gait for analysis. Powerful AI models will integrate this multi-dimensional user data to customize the shoe's support for pronation and supination on an individual basis. The app will additionally facilitate direct e-commerce functions for purchasing customized pairs. An engaging mobile-first design focusing on usability and data privacy will optimize the user experience. Potential freelance candidates should have proven experience developing full-stack projects, with an emphasis on front-end skills like React and backend abilities in Python frameworks. Proficiency in computer vision, deep learning, and a cloud infrastructure is desired for training models and processing multimedia assets at scale. Overall, this project aims to leverage cutting-edge technologies to deliver personalized running gear and aftercare through a hassle-free digital platform.

AI-Powered Video Analysis for 50–100 Soccer Training Exercises

This project aims to develop an AI-powered video analysis system for a mobile soccer training application. The system will analyze user-uploaded video recordings of soccer drills to track the ball and player movements. Key objectives include detecting repetitions, sequences, rule compliance for exercises like juggling and kicking drills. The analysis will output metrics such as repetition count, time taken, foot usage to provide automated feedback. Developers are sought to build a prototype analyzing 5 drills, scaling to 100, along with modular code, an API and accuracy benchmarks integrating with a React Native/Flutter app concept. Strong skills in computer vision, pose estimation, objection detection with YOLOv8 and mediapipe are required. The deliverables will be milestone-driven with an open budget discussed.

Prezi Presentation

We are a law firm specialising in immigration and employment and we host webinars on a weekly basis. We rely very heavily on PowerPoints, and I am very keen to get away from them as I think they are incredibly boring and there's nothing worse than somebody reading what's written on a slide which is the trap that all lawyers fall into. I want visuals that the audience enjoy watching whilst the lawyers are presenting the law. I appreciate from the site most freelances charge for a certain number of prezi slides so what I would like to do is for you to pick a random selection of the power point slides so we can get a feel for your thoughts and ideas. Whilst writing I confirm we've put this out to a number of Prezi experts. On receipt of your slides and proposal , we will review and we are looking to award a contract to do all of our webinars until December. This particular pack I've sent you is very very dry, approximately 20 slides but as above please just pick a selection just so we get a feel for your ideas. If you require any further information beforehand please contact me. As you can appreciate our branding is very important and the logo is on the PowerPoint. We do have a shorter logo but again at this stage just for the proposal we're happy for you to roll with what you've got on the PowerPoints. If you require any further information do not hesitate to contact me and we're looking forward to receiving your ideas.
