I am only a regular member there, yet I’d like to pull out just the recently active accounts and move them into a second channel that I own and administer. Here is what I need from you: • A working method (Python / Telethon, TDLib, or another reliable approach) to scrape the member list, filter for users who have been active recently, and then add them to my destination channel automatically. • The solution must cope with Telegram’s rate limits and any relevant policies, so batching and delay logic are essential. • A short read-me that lets me rerun the process whenever I want, plus any API keys or configuration tips required. • Proof of concept: after we test, at least a small samp...

    I run a public Telegram channel with 30 000+ members but only a fraction appear truly active. I need a specialist who can dive into the Telegram API / MTProto from the vantage point of a regular member account and tell me, with evidence, exactly what member-level data is retrievable. The priority is clear: I want to know whether user IDs and usernames can be enumerated, how many can be reached, and under which technical or policy constraints. While you are exploring, please note any practical way to spot genuinely engaged users, describe the rate limits you hit, and flag the differences I would face if I ever upgraded the account’s role. Deliverables • A concise proof-of-concept script or notebook that demonstrates the maximum data you were able to pull as a standard member, i...

    I need a lightweight key-logging application that runs silently on Windows and continuously captures every keystroke. The program must bundle those logs and forward them automatically to both an email address and a Telegram chat that I will specify during setup. Stability and stealth are important: the executable should start with Windows, avoid triggering Defender, and write minimal footprints to disk. Logs have to arrive in near-real time or on a schedule I can change in a simple config file. Deliverables: • A compiled Windows installer or standalone executable • A brief setup guide showing how to enter my SMTP credentials and Telegram bot token / chat ID • Source code so I can review and recompile if needed Please keep external dependencies to a minimum and...

    Our production platform is running well, but every now and then a functional bug slips through. When that happens I reach out by email and need a senior engineer who can jump straight in, diagnose the root cause, and ship a fix without disrupting business hours. Tech stack you’ll be touching: • Python / Django • Celery for background jobs • Redis for caching and as the Celery broker • Daphne with Django Channels powering WebSockets Because most of the hiccups we’ve seen are classic functional bugs rather than performance or integration issues, I value someone who can trace application logic fast and write clear, maintainable patches. We don’t have a fancy tracker—issues are reported manually by the team—so concise communication ...

    I need reliable, automated access to a local website dedicated to the diamond industry so I can stay ahead of pricing movements, changing inventory levels, and broader market trends. The site is public but does not offer an API, so web-scraping (Python, BeautifulSoup, Selenium, or a comparable solution) will be required. Here’s exactly what I expect: • A scraper that pulls the latest pricing information, inventory quantities, and any market-trend indicators you can extract from the pages. • Two report formats: a concise daily snapshot and a more detailed weekly overview. Both must arrive ready-to-read (CSV or Google Sheet is fine; a short PDF summary for the weekly report would be ideal). • A reusable “prompt package” that lets me drop the fresh data...

    My WhatsApp Business account is already fully verified; the missing piece is a live Meta app that lets me run large-scale marketing broadcasts through the official Cloud API. I need you to step in, create the app in Meta’s developer portal, complete all required configurations (system user, phone number, webhooks, message templates), guide it through App Review, and hand it over ready for production traffic. Once the app is live I want to be able to send segmented promos, coupons, and new-product announcements directly from my backend, so please wire up a lightweight example endpoint or script (Node.js or Python is fine) that shows how to trigger a broadcast to an uploaded contact list and how to pull delivery analytics. To keep the hand-off smooth, make sure the final setup covers...

    I’m building a fully-featured fintech website and need an experienced developer to take it from concept to production. The platform must let end-users create an account, sign in with a traditional email-and-password flow, and then manage their finances through an elegant, mobile-responsive interface. Core modules will include user authentication, personalised dashboards, payment or transaction handling, rich data visualisations, and a lightweight admin panel. Strong application-level security (OWASP best practices, encrypted credentials, rate limiting) is mandatory, as is fast performance on both desktop and mobile. My preferred stack is React or on the front end, backed by Node.js or Python services that talk to a PostgreSQL database and external payment/banking APIs. I inten...

    I’m creating a complete historical total-conversion mod for Mount & Blade: Warband and need an experienced modder who can take the concept from rough notes to a fully playable release. The goal is to replace every native asset that matters—world map, factions, troops, dialogs, equipment, music and UI—so the game feels as though it was originally set in the chosen historical period. You should already be comfortable with the Warband Module System (Python), OpenBRF for mesh and texture work, and the typical companion tools such as Morgh’s Editor or Blender when custom models are required. If you have experience scripting advanced features like diplomacy, formation AI or custom settlement mechanics, that will help the mod stand out. Deliverables • A co...

    I want to guide a small group of absolute beginners all the way to the point where they can land an entry-level role in AI, machine learning and generative AI. To get there, I’ll need a mentor who can design and deliver a complete learning journey—covering core theory just enough to ground them, then pivoting quickly into hands-on coding, model training and project work that showcases real-world skills. Here’s what I’m expecting from you: • A clear, modular curriculum that progresses from Python basics through classic machine-learning workflows and on to modern generative models (GPT-style LLMs, diffusion, etc.). • Live or recorded sessions with practical demos, Jupyter notebooks and datasets my trainees can keep experimenting with after class. •...

    I have a sizeable set of sales transactions exported directly from my e-commerce platform and I need a clear, insight-driven analysis that helps me understand the market forces reflected in those numbers. Your task is to dive into this raw sales data, clean and structure it, then surface trends that answer key market research questions: What products or categories are gaining momentum, which customer segments are buying when and why, and how do seasonal or promotional events shift demand? I would like the final work delivered as: • A cleaned, well-documented dataset (CSV or database table) that I can reuse. • A concise written report highlighting the main findings, supported by visuals. • Interactive dashboards (Tableau, Power BI, or similar) so I can explore the trends...

    I need help turning a sizable collection of unstructured finance-related text and document feeds into an accurate, production-ready predictive model. My goal is to spot patterns that reliably forecast the target variables I will share once we start (think risk scores and market-driven KPIs). The raw inputs arrive as news articles, earnings transcripts, and PDF reports, so the first step is a solid NLP-centric pipeline that cleans, tokenises, and extracts meaningful features. I work in a regulated environment, which means the code must be reproducible, well-commented, and easy to audit. Python with libraries such as spaCy, Hugging Face Transformers, pandas, and scikit-learn—or an equivalent stack—makes the most sense to me, but I’m open to a better suggestion as long as i...
