I am launching a free volunteer-run English club in Tokyo Japan for elementary school kids age 6-12. The idea is simple: give kids a relaxed place to build confidence in every core English skill—speaking, listening, reading and writing—while also making new friends and having fun. Where I need your expertise is in turning this vision into a practical, well-structured program that volunteers can pick up and run smoothly week after week. The sessions will revolve around games, storytelling, arts & crafts, plenty of English singing and dancing, the occasional field trip, guest speakers, and even music or dance recitals. If you have experience designing ESL curricula for young learners, organising community events, or creating engaging, hands-on lesson materials, y...

...hands-on technical projects that will stretch my programming abilities and would like a seasoned developer to guide the process. The core of this engagement is simple: you design a stream of bite-sized yet progressively challenging coding tasks, I complete them, and you review my work with clear, actionable feedback. My immediate focus is programming, so languages such as Python, JavaScript, or Java are ideal starting points, though I’m open to others if you can show why they add value. Each task should highlight a distinct concept—data structures, algorithms, version control practices, test-driven development, or clean code techniques—so I can build a well-rounded skill set while producing tangible portfolio pieces.

I want a ready-to-play Java Minecraft modpack that recreates the money-making loop of the game “Mine Moguls.” The core gameplay should revolve around three pillars: players mine a variety of ores, sell those ores for currency, then spend that currency on progressively better gear and automated machinery. Gameplay & balance • Use the Create mod for all mechanical processing, drills, conveyers, crushers, and automated packing. • Handle the economy with Create : Numismatic so every ore automatically converts to coins that can be spent in in-game shops or vending machines for upgraded tools, belts, drills, and decorative add-ons. • Difficulty set to moderate: mobs and resource scarcity should challenge the player without feeling punishing.

...Facebook pages for years now. We have worked hard to perfect our content, reaching the perfect target audience and customer base. We frequently see our posts go viral, always with our target audience. PROBLEM: In mid March this suddenly changed with a single reel. The algorithm pushed one of our reels to go viral in overseas regions we do not do business with. Since this event, everything has changed. Meta keeps sharing our posts to random, overseas audiences we don’t ship to, and it’s hurting reach, engagement and sales. The algorithm is consistently pushing new content to these audiences, while hiding it from our niche audience and current followers. Even our searches and explore pages have been altered, displaying primarily overseas pages. We are getting s...

I need a registered patent practitioner to transform my AI-driven gaming algorithm innovations into a fully-fledged, filing-ready patent application. The core of the invention lies in novel algorithmic techniques that enhance in-game decision making and adaptability, so the claims must spotlight those computational advances rather than hardware or user-interface elements. Where I’m starting: I have a handful of legal notes and references (“Law”) but no formal write-up yet. You will therefore guide the entire process—prior-art search, claim strategy, detailed specification, flow-chart style drawings, and formatting to USPTO standards. Experience with software and artificial-intelligence patents is essential; familiarity with gaming technology terminology and ...

I’m building a smart fitness companion that adapts every workout to how much discomfort a user is feeling that day. The core of the product is an algorithm that generates personalized plans, asks the user to rate their pain on a simple in-app scale, and then adjusts intensity, exercise selection, and rest periods automatically. Over time it should learn from completed sessions and update routines while presenting clear progress trends so the user can see where they’re improving without aggravating problem areas. Here’s what matters most: • Personalized fitness plans generated by AI. • Live pain-level monitoring through self-reported scales (no wearables in the first release). • Visual progress tracking that highlights correlations between pain...
