I have several datasets that need to be transformed into clean, well-structured information. At this stage I’m still defining the exact scope, so I’m open to a range of data-writing approaches—whether that involves straightforward data entry from spreadsheets, deeper analytical summaries drawn from a database, or shaping web-scraped records into a narrative that can power a report, a machine-learning pipeline, or an interactive dashboard. Here’s what I need from you: • A brief outline of how you would tackle the job once you see the raw files. • Your preferred tools—Excel, SQL, Python (Pandas, NumPy), or any other stack you’re comfortable with. • A sample of comparable work, if available, so I can gauge fit and style. • An es...

I have a collection of scientific articles in text form and I want a clear, reproducible way to uncover the key themes and topics running through them. The core of the task is natural-language processing: ingest the articles, clean and normalize the text, then apply topic-modeling or similar techniques to surface the dominant concepts. My preference is a Python-based workflow—think spaCy, NLTK, gensim, BERTopic, or comparable libraries—but I’m open to whatever stack you feel will give the most coherent results. Visual summaries such as word clouds or interactive topic maps are definitely welcome if they help make the findings intuitive. Deliverables • Well-commented code or notebook that I can run locally without tweaks • A short methodological write-up ...

I need an accurate list of 50–60 contract real-estate photographers who actively cover the corridor between Baltimore, MD and Richmond, VA. The goal is simple: I want to network with these shooters, so provide as many verified details as possible—name, direct phone number, email address and/or Instagram/Linkedin/Facebook accounts. I already have a shortlist of regional real-estate photography and media companies; I’ll pass that along at kickoff so you can mine their rosters first and then branch out to comparable firms or independent contractors in the same service area. You may use public directories, social platforms, company team pages, or direct outreach—whatever works, as long as the data is reliable. Acceptance criteria • 50–60 unique photographer...

I want to automate the hunt for future franchise partners in mortgage financing across Switzerland. The agent you build should scour professional networks, public directories, and relevant forums, then apply three non-negotiable filters: the person lives in Switzerland, has previous mortgage-financing experience, and shows clear interest in independent franchise opportunities. Once qualified, each lead must receive a short, personalised email—sent in French, English, or German depending on their profile—introducing our franchise model and inviting a call. One important point - franchise is not too popular in Switzerland. We might need to be a bit more open to people who are not actively looking for franchise opportunities, but are in general unexcited about their job and/or th...

I need a deep-dive study of the Food & Beverages segment of our country’s FMCG market. The work must blend solid consumer research with a clear reading of the wider market, so that by the end I can see both what shoppers feel today and where category demand is heading next. Scope • Consumer side – gauge satisfaction drivers, pain points, frequency of purchase, preferred price points and emerging taste shifts. Primary data collection (online panels, in-store intercepts or phone) is essential; I’ll rely on you to recommend the most cost-effective mix and execute it. • Market side – size the category, map growth pockets, and benchmark the leading brands against challenger labels. Secondary sources such as Nielsen, Euromonitor, Statista or government ...

I need a Natural Language Processing solution that accurately classifies social-media posts into predefined categories. The raw text will be provided in CSV format; it comes directly from public platforms and carries the usual noise—emojis, hashtags, abbreviations, and mixed languages—so an effective preprocessing pipeline is as important as the model itself. Here is how I picture the workflow. • Data handling: robust cleaning, tokenisation, and normalisation that respects emojis and common social-media shorthand. • Model building: a modern text-classification architecture (transformers via HuggingFace, or a lightweight scikit-learn baseline if you can justify comparable performance). • Training & evaluation: use train/validation/test splits and report ...

I need a fresh list of 100 % verified buyer contacts so we can expand our export sales for self-locking socket wrench tools and related hand-tool lines. The priority markets are the USA, the UK, and the UAE, and the companies that matter most to us are tool importers or distributors, hardware wholesalers, automotive-tool specialists, and, for our rebar couplers, medium-to-large construction companies. Scope of work • Source decision-makers (purchase, sourcing, or procurement) from the target company profiles above. • Deliver a minimum of 1 lead per company with accurate name, job title, company, country, work email, direct phone (when available), and LinkedIn URL. • All data must be recent and validated; hard-bounced emails or generic addresses (info@, sales@) will no...

I’m launching a new training calendar and the first item on the list is an Artificial Intelligence & Machine Learning batch that must dive straight into advanced territory. The cohort already has solid foundations, so the sessions need to centre on Deep Learning—building, tuning and deploying neural-network models with real-world datasets. If you’re also comfortable branching into Reinforcement Learning or NLP later, that flexibility will be a plus for the longer roadmap, but the immediate priority is Deep Learning mastery. The sessions will be delivered live (online or hybrid can be arranged), and I’ll rely on you to: • Shape a clear, week-by-week syllabus covering CNNs, RNNs, transformers, optimisation tricks, model interpretability and MLOps basics usi...

I have already fabricated both a conventional and a modified CCO, measured their performances, and logged every parameter in one consolidated Excel sheet. What I still need is a Python-based machine-learning workflow that learns from those results, predicts the required transistor W/L ratio for any new specification, and then surfaces the best-performing, fully optimised design point. The dataset is cleanly organised in Excel columns, but it still needs to be split into training, validation, and test sets, with any necessary feature engineering you judge appropriate. I have no fixed preference on the final algorithm—linear models, tree ensembles, or a small neural network are all acceptable as long as they deliver solid predictive accuracy and are easy to retrain when I add more dat...

I have one photo and need to trace it back to its original Instagram account as quickly as possible. Share the image with me only after we start our chat; once you have it, your task is to pinpoint the exact profile where it was first posted—or at least the earliest source you can reliably verify. You should already feel comfortable using the usual mix of Google Images, Yandex, TinEye, Face Recognition services, metadata checks, and any private-indexing tricks you rely on. Speed matters here; I’m hoping for a same-day turnaround if the match exists. Deliverables (all mandatory): • Direct URL to the Instagram profile you believe the image belongs to • Screenshot evidence of the match and date stamp proving earliest appearance • Short note (2-3 lines) on th...

I need help building a carefully curated list of YouTube channels that stream or publish real-time cryptocurrency market analysis every day. Your job is to search the platform manually, judge whether each channel truly delivers live or mixed live/recorded coverage of crypto prices, news, and charts, and then log only what you can verify from publicly visible sources—no scraping that breaks YouTube’s rules and absolutely no direct outreach. Here’s the structure I want captured in a Google Sheet: • Channel name • Channel URL • Estimated subscriber count • Content type ­– flag as live, mixed, or recorded based on what you observe • Language • Posting frequency (I am interested in channels posting daily) • Any public ...

looking for scraping expert with experience in scraping with different moduls

I have several public websites from which I need specific information gathered by hand rather than through automated scraping. You will visit each page I provide, extract the required details with care, and record them accurately in the spreadsheet template I share at the start of the project. Because this is manual work, close attention to spelling, consistent formatting, and absolute accuracy are essential. I will review the first batch you return and give immediate feedback so the rest of the job runs smoothly. The volume is straightforward for anyone experienced in data entry, and I am ready to start as soon as I select the right person. If you have completed similar manual website extractions before, mention an example so I can see your approach.

I need a steady stream of verified, high-intent prospects for our freight-forwarding operations platform. The entire focus is on small businesses in the shipping and freight-forwarding space, and the reach must be truly international rather than confined to any single region. Your task is to research, identify, and deliver contact data for company owners or operations decision-makers who fit this profile. I expect each record to include company name, website, country, contact person, title, work email, telephone (when available), and a short note confirming why the lead matches the criteria. All emails must pass standard validation tools such as NeverBounce or ZeroBounce. Please begin with a small sample so I can vet accuracy and relevance; once approved, we can move on to larger batches...
