Our custom construction ERP is in the final stretch. The core modules are in place, but three areas still block go-live: 1. Sales pipeline – Automation & workflows I have the UI and basic routes, yet deals do not progress automatically through stages, nor do the triggers for emails, task creation, and forecast updates fire reliably. I need you to hard-wire the logic in Node.js/Express and make sure the jQuery / Select2 front-end reflects every state change instantly. 2. PostgreSQL – Connection issues Under load the app occasionally drops connections and stalls. The schema relies on complex JOINs and several polymorphic associations, so I need a deep dive into pooling, transaction handling, and any rogue long-running queries that may starve connections. Fixes must ...

I need a fresh, well-structured database of original multiple-choice questions for MH-CET that fully covers Mathematics, Physics, Chemistry, and Biology. Each question must be paired with a clear, step-by-step explanation that shows how the correct answer is reached and, where helpful, why the distractors are wrong. Total numbers of questions are avarage 10000 to 12000 included all subjects The end product should allow me to filter questions quickly by subject, chapter, sub-topic, and difficulty level, so organising the content in Excel, Google Sheets, or an SQL table makes sense. If you already have a more efficient system, describe it and I’ll consider it. Accuracy must align with the latest MH-CET syllabus and typical exam pattern. Deliverables • A single file (or databas...

I need a compact module that connects to my SQL Server database, fetches raw attendance data, and delivers a clean report that mirrors the sample layout I will share. Two filters must work flawlessly and in combination: date-wise and employee-wise—both hold equal weight for daily use. Any duplicate rows you encounter should be excluded before the data reaches the final grid or export. My preference is an ASP.NET / C# backend, though you’re free to craft the stored procedures as you see fit. Once the dataset is shaped, the user should be able to export the report to both Excel and PDF with a single click, keeping the exact formatting intact (headers, column order, totals, page breaks). Deliverables I expect: • A ready-to-run report with source code • Brief setup no...

I need a developer who can build a compact ERP system tailored to a recruitment-focused operation that also handles day-to-day finance. Core recruitment functions—applicant tracking, structured onboarding, and multi-channel job posting—must sit seamlessly beside standard finance workflows such as invoicing, expense logging, and basic reporting. The flow I envision is simple: candidates are sourced, tracked through each hiring stage, converted to employees once onboarded, and their payroll and billing data feed directly into the finance area without manual re-entry. A clean, browser-based interface is preferred so my team can work from any location. Deliverables • A working web ERP with the three recruitment features running end-to-end • Integrated finance sectio...

I’m looking for a fresh 2026 updated dataset of U.S. residential contacts that I can drop straight into my campaigns without worrying about bad emails or dead phone numbers. The file must cover every state and include only individuals aged 45 or older. For each contact I need a full name, a working email address, and a reachable phone number. Approx data count according to the USA demographics should be around 100-120 millions I’ll be running the list through ZeroBounce and similar verification tools, so I expect a true 0 % bounce rate. Please deliver everything as a statewise well-structured CSV so I can import it immediately. Deliverables • One/Multiple CSV containing validated records (name, email, phone, age 45+) for all 50 states • Verification repo...

Looking for SQL expert who has experience with the stored procedures to debug and fix the errors

I quote jobs for drilling multiple holes into solid steel bars that range from 1.5 in to 12 in in diameter. Hole diameters vary from 0.75 in, 1 in, 1.5 in, 2 in, all the way up to 8 in, and a single bar can have any number of these holes spaced along its full length. Right now I juggle the numbers in a spreadsheet, but I need a faster, cleaner way. Please build the solution in FileMaker Pro. The calculator must let me choose the run size (bar diameter) and each branch size (hole diameter) from drop-down menus, enter the quantity of identical holes, and then return an instant price. The pricing logic is advanced: it has to consider the run size, every hole size, and the total number of holes, with the flexibility to factor in changes to material, labour, or machine rates later. I’d ...

Trabajo con Odoo y necesito reforzar el esquema de seguridad y pulir algunos flujos clave: 1.

I need a lightweight MVP website built that lets visitors type a name into a search box and instantly see a dynamic page generated from the underlying data. All content will live in a small database, so new entries automatically create new pages without manual coding. A clean, minimalist interface is important, but the code structure has to be equally tidy—SEO-friendly URLs, proper meta hierarchy, and an ad-ready layout so I can drop in display ads later without redesigning anything. Core scope • Search: a simple, name-based lookup that returns an exact or closest match. • Dynamic pages: rendered server-side from database content, not static files. • Database: whichever stack you recommend as fastest to spin up and scale for a light workload. • Front-end:...

I have two nearly identical Excel workbooks—each with approximately 300 rows and columns A through AE—that need to be merged into a single, clean master sheet, which is already established. The goal is to streamline our data management by ensuring every record is transferred accurately and all duplicates are eliminated using an automated duplicate-checking tool, rather than manual review. The finished file must reach me by Wednesday, 16 April 2026, midday AET.

I am building an automated question-paper generator and I need a steady stream of original, curriculum-aligned content to feed into it. The subjects in scope right now are Mathematics, Science, History and Geography. For each of these, I will need every standard classroom format covered—multiple-choice, short-answer and full essay questions—each paired with a clear, accurate answer key or marking guide so the software can score automatically. If you have solid experience writing educational material, please tell me where and for whom you have produced it before; that context matters more to me than formal proposals. Familiarity with syllabus mapping, Bloom’s taxonomy or similar frameworks will be a plus, but the core requirement is the ability to create clear, well-grade...

I’m putting together a full-featured hostel management system and need an experienced developer who can deliver the entire platform from database to user interface. Core modules must cover room allocation, fee management, student records, visitor logging and attendance. On top of that, I also want an events module so staff can announce activities, collect RSVPs and track turnout. Both staff and students will use the system, so role-based access, separate dashboards and mobile-friendly screens are essential. I expect clean navigation, secure login, searchable listings and exportable reports (PDF/Excel) for finance and occupancy. Please build the project with a well-structured codebase and include: • Fully functional web app (source code) • SQL schema and sample data for...

I’m looking for a reliable computer operator who can keep our day-to-day information flowing smoothly. Your core focus will be entering new database records with speed and accuracy, watching over system dashboards to catch issues before they turn into problems, and turning raw activity logs into clear, well-structured reports for management. You’ll work directly inside our database interface for record entry, using Notepad whenever you need a quick scratch-pad or to clean up text before pasting it into the system. While the data itself is structured, attention to detail is critical because any typo can ripple through multiple departments. On the monitoring side, I’ll count on you to keep an eye on resource usage, job queues, and error alerts, then note anything unusual s...

I’m in the start of a performance-focused data-migration effort that moves our current datasets into Snowflake, with Geneva and straight SQL powering the pipelines. To keep momentum, I need someone who can help on the hands-on analyst work while thinking like a Business Data Analyst. What I still have to finish centres on two areas: • Data extraction and transformation – mapping existing schemas, writing efficient SQL, and using Geneva/Snowflake utilities to cleanse and reshape data so downstream analytics run faster. • Data loading and validation – building repeatable load jobs into Snowflake, designing row-level and aggregate checks, and documenting reconciliation so stakeholders can trust the numbers. Acceptance criteria • Clean, reusable ETL scripts ...
