I have a single formula in my Excel sheet that is meant to process te...I’m clearly referencing the wrong cells, using the wrong function, or missing some subtle syntax. I’m not certain which functions are best suited here; it could be a VLOOKUP, TEXTJOIN, IF combination, or something entirely different. What I need from you is straightforward: open the workbook, pinpoint why the current formula misbehaves with my text data, then rewrite or restructure it so every row returns the correct output. A brief note explaining the changes will help me keep this clear for future edits. Deliverable: • Updated, working formula in the sheet, fully tested against my current dataset, plus a short explanation of the fix. If you’ve untangled similar Excel logic before, thi...

I need a steady stream of fresh, accurate leads pulled from and DesignRush. Each batch should contain unique digital agencies and follow the simple pay-per-batch model sof $3/1,000 clean verifiable leads. What every row must include (in this exact order): • Company Name • Email Address (plain text, not hyperlinked) • Website URL • Company Location Please export the data to a clean CSV, double-check for duplicates across both platforms, and verify that each email belongs to the same domain as the listed website. Agencies outside the digital space or missing any of the required fields should be skipped.

I am setting up a lightweight CRM/ERP on the Buildzor no-code platform and want Buildzor (No code application development platform) creator to turn my process maps into working forms and their matching reports. The scope centres on functional areas may differ application to application as per client requirement: An additional requirement is a one-way sync from the CRM into my existing accounting software; once the basic connector is wired up I will supply the API key and field mapping. Acceptance criteria • Each form is live, responsive and secured with Buildzor’s role permissions. • Reports pull the exact data set defined during hand-off and refresh automatically. • Accounting sync pushes new invoices without errors and logs the transaction ID insi...

I have a set of PDFs that contain purely संख्यात्मक डेटा. Every number in those files needs to land in the correct cell of an Excel workbook so that the sheets are ready for immediate calculation and analysis. Accuracy is critical here; the figures must match the source without a single digit lost or transposed. Clean column-row alignment is equally important, but apart from that I do not require any elaborate re-formatting. If you spot inconsistencies or obvious scanning errors in the source, flag them so I can confirm the intended value before you proceed. You may use whatever extraction method suits you best—manual entry, OCR, or a mix—as long as the final spreadsheet is 100 % true to the originals and delivered on schedule in .xlsx format. Please inc...

I have a well-structured Excel sheet that already handles every pricing rule I need. What I want ...their own sessions and saved quotes. • Exports: one-tap PDF generation of the final price breakdown, ready to email straight from the device. • Live accuracy: anytime I tweak values or formulas, the app should reflect the change immediately without re-publishing. Doesn't have to be Glide but that's what I was recommended. 1. A fully functioning project with editor access. 2. The linked data source(s). 3. A brief Loom or written walkthrough showing how I can adjust pricing tiers later.

# Migrating a production application from a single-table key-value store to a normalized relational schema on Supabase Postgres. This migration replaces that flat KV layer with ~15–20 purpose-built tables, proper indexing, and Row-Level Security — all without downtime. # The frontend component layer stays untouched. This is a data layer project: schema design, API endpoints, and the persistence plumbing underneath the UI. # What You'll Build—The migration runs in four phases: - Phase 1 — Parallel Infrastructure Create the new relational tables alongside the existing KV table. Implement a dual-write layer so every write goes to both stores simultaneously. Run a one-time backfill script to hydrate the new tables from existing KV data. - Phase 2 — R...

I’m assembling a squad of eight seasoned Amazon-to-eBay dropshippers and I’d like to see what you can do before we scale up. Your first paid task is simple but telling: find 50 high-demand products that can be purchased directly from Amazon and are ready to move on eBay. Only product sourcing is on your plate—other team members handle the listings and order flow—so all of your attention should go into spotting items with proven buyer interest. For each pick, send me a quick spreadsheet containing the Amazon link, a concise title, the current Amazon price and the going-rate snapshot on eBay. With that I can confirm demand and green-light the next batch. Turnaround on the initial 50 should be fast (ideally within 48 hours of award). Deliver clean, accurate data and ...

...This engagement is for the architecture phase only. A separate engineering team will implement under your direction. We are seeking a Principal Infrastructure Architect who has designed secure, compliance-ready multi-tenant SaaS systems in production. This is not a coding role.

You will be responsible for planning, coding, testing, deployment and final hand-over; I don’t plan to split this into isolated tasks. Daily stand-ups, Git-flow, code reviews and an automated CI/CD pipeline are expected so we can iterate quickly and keep quality high. Core technologies The stack already outlined includes JavaScript/React (React Native on the client), Python/Django and Java/Spring for backend services, plus Dart/Flutter for rapid UI prototyping. Parts of an existing C++ library will need to be wrapped for mobile, so familiarity with native module bridging is important. Deliverables • A milestone-driven roadmap and sprin...

I have an Excel workbook that only needs the existing text swapped out for new wording I will supply in a second Excel file. Every column, row, and target cell is already mapped, so the job is a straight-forward copy-and-paste exercise—no formulas or formatting changes involved. If you can deliver the updated file accurately within about three hours (it usually goes faster once you get into a rhythm) and double-check that every specified cell is replaced while nothing else in the sheet is altered, I’ll have similar batches for you on a regular basis. Low hourly bids are encouraged, but reliability and accuracy come first. job needs to be done within 3-4 hours upon assigning it.

My service includes: - User registration and login - JWT authentication - Protected API endpoints - Admin panel - Clean and secure code - GitHub source code
