Full-Stack Developer for Business Operations

Summary Project Overview We are a manufacturing company with our own delivery fleet, supplying our products to customers across the island. We are looking for an experienced developer (or small team) who can analyze our existing workflow and build a modern solution to automate and simplify our operations. Our Current Workflow 1. Customers place their orders via WhatsApp, usually one day before delivery. 2. A staff member manually copies every order from WhatsApp onto paper. 3. Orders are grouped by delivery region. 4. The processing department receives the handwritten orders and prepares the products for each region. 5. Once processing is completed, invoices are manually created. 6. All invoices are written and handed to the drivers before deliveries. 7. At the end of the day, drivers return with payments collected from customers. 8. Payments (cash, cheque, or bank transfer) are then manually reconciled. Product Pricing & Weight Calculation We deal primarily in fresh chicken products, and our pricing is based on net weight (kg). However, customers may place their orders either by pieces (pcs) or kilograms (kg), depending on their preference. Each customer may also have their own negotiated pricing, so the system must support customer-specific price lists. During processing, the products are packed into crates before dispatch. Each crate has a different tare weight (typically 1 kg, 1.9 kg, 2 kg, 3 kg, or 4 kg). For example, if a customer orders 50 pieces of chicken, the order may be packed into 6 or 7 crates with varying tare weights. The processing staff records the gross weight and the tare weight of the crates, and the system must automatically calculate the net product weight (Gross Weight − Total Tare Weight). The customer is then invoiced based on the net weight, using their agreed price per kilogram. Order Complexity We currently manufacture and sell approximately 50 different chicken products. The system must support customers ordering any combination of these products in a single order. As our business grows, the solution should efficiently handle large multi-line orders while ensuring accurate order processing, production planning, invoicing, and delivery. The application should remain fast, reliable, and easy to use even when processing complex orders with many different product lines. Delivery Adjustments & Exceptions As we deal with fresh chicken products, the invoiced quantities may occasionally need to be adjusted during delivery. Some customers choose to verify the weight of the products upon receipt. If the measured weight is lower than the invoiced net weight, the driver contacts the office and the invoice must be adjusted so that the customer is charged only for the weight actually received. If the delivered weight is higher than the invoiced weight, no adjustment is required. In addition, there are occasions where a driver may inadvertently leave one or more items at the factory. In such cases, the driver contacts the office from the customer's location, and the missing items must be removed from the invoice so that the customer is billed only for the products that were successfully delivered. The system should make these delivery-time adjustments simple, fully traceable, and synchronized with the final invoice and payment records. Our workflow involves many real-world operational exceptions that cannot always be anticipated. We are looking for a developer who can design a flexible system capable of handling these scenarios without requiring manual workarounds or software changes each time a new business rule arises. While this process works, it requires a significant amount of manual work, duplicate data entry, printed paperwork, and repetitive administrative tasks. What We Are Looking For We are looking for someone who can study our workflow, understand our business processes, and propose a modern, scalable solution. We are open to suggestions if there are better ways to improve our operations.

React, Node Postgress Developer

We have a software project that is almost complete, but unfortunately the original developer has become unresponsive, leaving us unable to launch. The project is based around the board game **Backgammon**, which is also played online. Serious players analyse their matches using software called **Extreme Gammon (XG)**. Currently, every move from a match must be entered manually into XG, which is extremely time-consuming. Our platform, 'BackgammonAnalyst.com', aims to automate this process. Users upload a completed match, the software reads and reconstructs the game, and generates an output that can be imported into XG for analysis, dramatically reducing the time and effort required. You can view the current website at **BackgammonAnalyst.com**. From our assessment, there are relatively few changes remaining on the desktop version, with a little more work required on the mobile web version. However, we have not yet seen the software fully working, either via a live demonstration or a comprehensive video. We have our own server infrastructure and a dedicated server administrator. The first task would be to assess whether all source code has been deployed correctly, review the current state of the project, and thoroughly test the application to identify any remaining issues before completing the outstanding work. The product was scheduled to launch this coming Friday/Saturday. We appreciate this is ambitious, but if the remaining work is genuinely limited, there may still be an opportunity to meet, or come very close to, that target. If this is a project you would be interested in reviewing, we would be happy to provide further information, access to the codebase, and discuss the next steps. You can view the amends: https://docs.google.com/document/d/1eMHSHC_IXyfQxUNWQkAYAjGRW8hwMIRKh--Zwk37aPI/edit?tab=t.0 The project fee can be a place holding initially.

FinTech Web Application Developer

Summary Project Summary: I want to develop a FinTech web application that allows users to invest in fractional shares of luxury cars. The platform features a user-friendly interface for browsing and purchasing shares, with secure payment processing and real-time market updates. Project Overview: The platform features two core investment mechanics. 1. TurboYield (Car Fractionalization): Users purchase fractional shares of a car to earn passive monthly income derived from rental revenue distributions. Example: A Porsche car is valued at ₹1 Crore. Total Shares Issued: 10,000. Price per share: ₹1,000. Car earns ₹5 lakh net revenue after expenses. Monthly Rental yield = 500000 ÷ 10000 shares = 50/share. 2. TurboFlip (Car Buy & Sell): Users pool capital to purchase a vehicle, which is then resold at a premium, returning the principal and profits back to investors. Example: A Mercedes G wagon is available at 1.5 crore. 150 Investors pool in money. (1 lakh each.) Car is purchased Car is re-sold at 20% premium (i.e. 1.8 crore net revenue after expenses) Payout to each Investor = 1.8 crore ÷ 150 = 1,20,000. Platform: Web-based app (optimized for desktop and mobile) OR Native Mobile Apps for iOS and Android. Preferred Tech Stack: Frontend & Mobile: Cross-platform frameworks like Flutter or React Native to deploy seamlessly to Web, iOS, and Android simultaneously. Backend: Node.js (Express), Python (Django/FastAPI), or Go for scalable backend API development. Database: PostgreSQL or MongoDB to safely manage transactional data, user accounts, and fractional investments Cloud & Infra: AWS, Google Cloud, or Firebase for secure hosting and scaling. Core Features & Technical Scope: 1. User Authentication & Onboarding • OTP-based signup and login via Mobile (SMS/WhatsApp) and Email • KYC compliance system (PAN, Aadhaar, and Bank Account verification) 2. Investor Dashboard / Members Area • Dashboard – invested amount, current value, total earned, shares owned • Cars (TurboYield) – shows a list of cars that users can buy shares of. When clicked, it opens vehicle details page, where users can select # of shares they wish to buy. • Cars (TurboFlip) – shows a list of cars that users can invest money. • Marketplace (p2p Exchange) – Users can sell their shares here. They can also buy shares listed by other users. • Rewards – e.g. users who own 10 shares get a chance to win an iPhone every quarter. They can choose their own 6-digit number and enter the draw. • Refer & earn – Users can refer others to sign-up and get paid a commission. • Wallet – Members can top-up their account here. Also, payouts from admin are credited to the wallet. They can withdraw to their bank account from here. • Profile – Members profile, KYC details etc. 3. Centralized Admin Console • Overview – shows metrics like total users, # of investors, invested amount etc. • Users – list of users and management. • KYC – pending KYC approvals are reviewed by admin here. • Manage Cars (TurboYield and TurboFlip)– add and manage cars • Payouts – calculate and manage monthly payouts or profit distribution. • Manual Payments – Review UPI / bank transfer submissions and approve • Withdrawals – Approve bank withdrawal requests • Settings – payment and general settings • Rewards & Draw – choose winners for iPhone draw 4.

Email Template Developer — Responsive HTML Newsletter Build

A UK-based ecommerce company is looking for a developer to build a set of reusable, responsive HTML email templates for our regular newsletter and campaign sends. We currently rebuild each email from scratch, which is slow and produces inconsistent results across inboxes. We want a small library of modular, well-coded templates we can reuse and populate ourselves, that render reliably everywhere from Apple Mail to Outlook. The work covers three master templates: a standard newsletter with stackable content blocks, a single-product promotional layout, and a plain transactional style for order and service messages. Each should be built from interchangeable modules — hero, text block, two-column, product row, button, footer — so our marketing team can assemble new emails by rearranging sections without writing code. Requirements for the build: bulletproof buttons, web-safe fallbacks for custom fonts, retina-ready images with correct fallbacks, dark mode handling, and full responsiveness down to narrow mobile widths. Everything must degrade gracefully in Outlook's rendering engine, which is the usual sticking point and where we will be looking most closely at your work. Inline CSS as required by email clients, with clear comments so our team can edit safely. Deliverables are the three master templates plus the module set, tested across the major desktop, mobile and webmail clients, with a short written record of which clients were tested and any known limitations. We will provide brand guidelines, fonts, imagery and example content. Copy and campaign setup are handled in-house; this is a build-only brief. To be considered, please share email templates you have personally coded, ideally with a link to a rendering test or live example, tell us how you approach Outlook rendering specifically, and confirm your availability. Applications without examples of email development will not be shortlisted.

Experience with Solidity or Rust, blockchain wallet integrations, Ethereum or other EVM-compatible networks, and development tools such as Hardhat or Foundry would be a plus. Your responsibilities will include developing new frontend and backend features, integrating blockchain functionality where required, improving existing code, optimizing performance, and collaborating throughout the project to deliver a high-quality application. When applying, please share a brief summary of your relevant experience, links to similar projects or your GitHub profile, your availability, and your expected hourly rate. I'm looking for a reliable developer who communicates well and can contribute consistently throughout the project.
