I’m juggling a full class schedule and could really use a dependable freelancer who can step in on an as-needed basis to keep my small projects moving. This is strictly freelance work, so you set your own hours—as long as deadlines are met. Most of the tasks are administrative in nature, but I’m open to handing off virtually anything that can be completed online. Typical responsibilities may include light data entry, basic document formatting, organising files in Google Drive, updating simple spreadsheets, researching information for school or personal projects, and keeping my email inbox tidy. If you have experience with Google Workspace, Microsoft Office, or similar cloud tools, you’ll feel right at home. Deliverables will vary week to week, but you can e...

I have a series of Excel sheets that hold raw customer information—names, addresses, contact numbers and a few free-text notes. All of this text data needs to be transferred accurately into our cloud-based database. Your task is straightforward: open each provided workbook, copy the relevant fields, paste or type them into the matching fields online, and double-check every record for exact spelling and formatting. No numerical calculations are involved; it is purely text entry and validation. Because the data concerns real customers, absolute accuracy and discretion are critical. I will supply a short style guide (capitalisation, phone-number format, forbidden abbreviations) and a login to the web portal. After a quick video walkthrough you can start right away. De...

I’m arranging a small online class for four Asian friends who want to feel more confident in everyday English. We have set aside one hour a week, 8-9 PM EST, and can meet either Wednesday or Saturday—whichever you can commit to consistently. We’ll begin with a ten-week block and hope to continue if everyone is happy with the progress. Their priority is simple, natural conversation: ordering food, chatting with coworkers, small talk, and other day-to-day topics. They learn best through interactive activities rather than rigid slide decks, so games, role-plays, and real-time feedback will be appreciated. All four are beginners, so patience, clear pronunciation, and the ability to explain idioms in plain language are essential. I’ll provide a stable Zoom link;...

... well-structured spreadsheets from raw data, shaping that information into clear financial reports, and keeping everything organized for timely GST filing. Once the numbers are in place I also rely on tidy, accurate supporting documents—think Word files that summarise findings and any workpapers that must be reviewed before submission. Every figure has to reconcile, every sheet must be error-free, and the final pack should be ready for upload to the GST portal without additional edits. Key deliverables: • Cleaned & organised data tables in Excel • Dynamic spreadsheets that drive my audit schedules • Concise financial reports ready for review • Supporting documents proof-read and formatted for compliance If you know your way around formul...

For each subject I want clear concept explanations followed immediately by practice so that learners can test understanding in real time.

I’m looking to extend the standard javac pipeline so that selected compile-time transformations flow seamlessly into runtime-level optimizations. The sole objective is measurable performance gains, and the hot spot I need addressed is the handling of function calls. Here’s the current thinking: • During compilation I want to inject bytecode-level hints or re-write patterns that the JVM’s JIT can exploit immediately at runtime. • The focus is on aggressive inlining, de-virtualization, and any other call-site refinement that reduces dispatch overhead without breaking portability. • I expect clear before-and-after benchmarks (micro-benchmarks are fine) proving the speed-up on a standard HotSpot JVM. Please bring practical experience with javac plugins...

I need a small Pine Script add-on (or even Java script) that looks at and recognize the text printed on the PREVIOUS candle of any TradingView chart, checks whether it contains the keywords “Buy” or “Sell”, and—if it does—immediately fires a webhook alert. Scope • Keyword detection only; no pattern recognition or number extraction involved. • Target words: “Buy” and “Sell”. The alert should trigger whenever either word is found, nothing else. • The scan must reference the candle that has just closed, so the alert goes out in real time for the next bar. • Webhook payload and URL should be easy for me to edit in the script parameters. Deliverable A single, commented Pine Script file that I can ...

I film short daily vlogs and want each one shaped into a clean, 30–60-second vertical reel that feels effortless rather than over-produced. You’ll receive raw clips straight from my phone; your task is to trim only what’s necessary, arrange the story chronologically, and add smooth, subtle transitions so the flow stays natural. Basic colour correction, audio levelling, and a light royalty-free music bed (nothing that overpowers my voice) complete the polish I’m after. Text overlays are minimal—just the occasional location or quick caption where context is needed. Deliverables • 4 finished reels per week, 1080 × 1920 MP4 • Consistent colour grade across all clips • Soft cross-dissolve or swipe transitions; no jump-cut mon...

...that will promote an upcoming event to a professional audience and work equally well on office walls and across our social channels. The design must translate cleanly from print (A3 and A4, CMYK, 300 dpi) to web (optimized JPEG/PNG for LinkedIn and email).
