From 152,902 reviews, clients rate our Database Development Experts 4.9 out of 5 stars.I need a full-stack web application built from concept to live deployment. This includes planning the architecture, designing an intuitive responsive interface, implementing secure back-end logic, integrating a database, writing clean APIs, and setting up automated tests as well as CI/CD pipelines. The finished app must run smoothly on modern browsers, scale easily in a cloud environment, and come with clear documentation so I can maintain or extend it later. Deliverables: • Complete source code in a Git repository • Deployed, production-ready instance on my chosen cloud host • Step-by-step setup and maintenance documentation • Basic test suite proving core functions work out of the box Acceptance criteria: the code installs with one command, all tests pass, and...
I need a new Cognos dashboard focused purely on data visualization. The dashboard will pull its figures from our existing SQL databases, so you’ll be working with relational data structures, writing efficient queries, and making sure refreshes stay fast even as record counts grow. The look and feel matter to me: clear charts, intuitive drill-downs, and a layout that lets managers grasp trends at a glance. If you have experience shaping Cognos visualizations with custom prompts, calculated fields, and conditional formatting, that’s exactly the skill set I’m after. Deliverables • A fully functional Cognos dashboard connected to the specified SQL sources • Reusable data modules and any query subjects you create • Brief setup notes so my internal admin ca...
I have an in-house VB.NET application backed by SQL Server 2008 R2 that currently schedules four 6-hour shifts per day. Operational changes now require three 8-hour shifts instead. The change touches two main areas: • Business logic – all routines that build the daily roster, assign staff and calculate shift boundaries work off the 4 × 6 model. • Database structure – several tables store fixed shift identifiers, start / end times, and downstream references that assume four records per day. Because the scheduling and allocation algorithms drive time-sensitive workflows, any adjustment must keep existing calculation accuracy intact. The user interface itself can stay as is; only back-end logic and schema need attention. What I need delivered 1. Updated ...

The goal is to create an organized tool that functions as an efficient database for registering and tracking animal batches from nursery placement to the finishing phase. The system must be able to manage and relate the following production stages: 1. Nursery Placement: * Integrated registration, placement date, number of animals, origin, truck license plate, and farm capacity. * The system must allow multiple placements for the same farm until its capacity is reached. 2. Vaccination Control: * Registration of vaccination date, vaccine name, number of vials used, and number of animals vaccinated. * It must allow m...
I look after supply management for a medical provider that serves the LGBTQ+ community. We have just consolidated everything into a single distribution hub, and from this point forward that hub will handle every inventory-related task for all of our clinic locations. To keep pace, I need our inventory tracking to move from manual spreadsheets to a fully automated, scalable workflow that plugs straight into the software stack we already use. First priority is real-time stock visibility. As soon as an item is received, dispensed, or transferred between sites I want its quantity to update instantly across the system. Barcode scanning at each touchpoint is essential so staff can work quickly without typing errors. Low-stock alerts will come later, but the foundation has to be bullet-proof tra...

I’m ready to commission a full-stack build of a trading website that can handle real-time market activity and everyday user operations without a hitch. The site must: • Stream live market data to every visitor with minimal latency. • Provide secure user account management for sign-up, login, KYC storage, and profile dashboards. • Run a robust backend that processes orders, positions, balances, and any other trading activity in a reliable, auditable way. You are free to suggest the best stack, but I expect industry-standard security practices, clear API design, and clean, well-documented code. Front-end styling does not need to be flashy—speed and accuracy take priority—yet it should remain intuitive on both desktop and mobile. Deliverables 1. Front...
I need a full-featured central monitoring application that talks seamlessly to Tuya-based panel alarm systems and Tuya cameras. The core requirements are: • Real-time alerts whenever a sensor, zone, or camera triggers • Live and archived video surveillance from all registered Tuya cameras • Continuous system-health monitoring so I can see device status, connectivity, and battery levels at a glance • Complete alarm-system arm, disarm, and event handling from the same dashboard The solution must run on a Windows server yet present everything through a clean, secure web interface that any modern browser can open—no thick desktop client. Please rely on Tuya’s official API/SDK (MQTT, HTTPS, WebRTC, etc.) so future firmware updates remain compatib...
I need two focused Python utilities that help me keep both of my data platforms tidy by flagging objects that haven’t been touched in X days and suggesting safe-to-drop SQL. Program #1 – AWS Athena • Connect to my Athena catalog (I work from the AWS Management Console, but in code I’d like you to stay with boto3). • For every table and view in a specified database, look back over completed query executions for the chosen time window. • Views can nest CTEs or reference other views, so the script must walk the full dependency chain to decide whether a reference is direct or indirect. • Return one CSV with the following columns exactly: database , objectname, objecttype, last_reference_datetime, referencetype (direct/indirect) , referencedBy,...
I need a single, cohesive Berkel tracker that lets me follow two things at once: where each technician is and what is happening with every item of stock. For the technicians I must see their real-time location on a map, push out tasks to them, watch those tasks move from assigned through to completed, and keep an activity log that I can export for later audits. For stock, I want a live view of inventory levels, a clear movement history so I always know who touched what and when, and a way to pinpoint the current location of any item in seconds. Please propose the platform, database and mapping tools you feel suit this best and outline a realistic timeline. Typical deliverables would include: • A responsive dashboard showing technician positions and stock KPIs in real time ...

I need a sizeable, up-to-date database of medium-sized U.S. companies that spans every sector—healthcare, retail, technology, and any other field you can reach. For every record I only require two data points: a direct phone number and a working email address and company name and person name. Accuracy matters more than sheer volume, so I’ll be checking for bounced emails, disconnected lines, and duplicates before releasing final approval. Please deliver the file in Excel. Include one row per company contact, clearly labeled columns, and make sure the data has been gathered ethically and is compliant with U.S. privacy laws. I will consider the job complete once: • at least 95 % of emails pass validation tools such as ZeroBounce or NeverBounce, • phone numbers are c...
I am building 630792Dooro as a dedicated software application for e-commerce and need a solid, production-ready shopping cart coded from the ground up.

Core objective • Design and implement a secure, scalable shopping cart that can handle item selection, quantity updates, discount codes, tax and shipping calculations, and checkout hand-off to a payment gateway. What you will deliver • Source code with clear, commented logic • Database schema or ORM models for cart persistence • Simple UI mock-ups or wireframes demonstrating cart flow • A short README explaining setup and build st...

I need a secure, well-structured database system dedicated to our school’s fee records. The core focus is capturing and managing payment transactions in real time, then making that information available to students and parents through a simple login interface. Key points • Database scope: fee payment transactions only (no grade or staff data for now). • Primary users: students and parents; an admin panel will still be required for me and my team to add, edit, or correct entries. • Access: web-based dashboard is preferred, yet I’m open to a lightweight API that could later feed a mobile app if you think that future-proofs the build. • Security: role-based permissions, encrypted credentials, and activity logs are must-haves. Deliverables 1. Nor...
