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. Backend Logic & Automation • Execution of a daily automated backend job (cron job) to calculate dynamic share pricing using revenue metrics. NOTE: I have a 3-page highly detailed technical specifications document with formula metrics and prototype links that I will share under a Non-Disclosure Agreement (NDA) once we pass the initial screening.

3D Printable Wall-Mounted Vertical Ant Farm Model Design Needed

I am looking for someone to design a vertical wall-mounted ant farm model that can be 3D printed. The model needs to be practical, secure, and designed properly for printing. It should be suitable for ants, with natural-looking tunnels and chambers visible from the front. The design will need to be supplied as printable STL/STEP files. ⸻ Main Design Requirements The ant farm should be designed as a vertical wall-mounted unit. It needs to: * Be easy and secure to wall mount. * Have a strong rear body/frame. * Include mounting holes or keyhole-style wall fixings. * Be stable once fitted to a wall. * Be suitable for 3D printing without unnecessary supports where possible. ⸻ Front Perspex Panel The front needs a recessed area to hold an A4 sheet of 3 mm Perspex. The Perspex size will be: 297 mm wide x 210 mm tall x 3 mm thick Please note: the Perspex must sit neatly into the front recess. The model also needs screw holes around the front so the Perspex can be fixed securely using M3 screws. I would like the screw holes positioned neatly around the Perspex, with enough support around them so the print does not crack when tightened. ⸻ Magnet Slots The model also needs small recesses for magnets to be glued into place. Magnet size: 4 mm wide x 2 mm deep These should be placed in sensible positions to help secure interchangeable side parts, covers, or connection pieces. The magnet holes should be slightly oversized to allow for glue and tolerance. ⸻ Natural Tunnel System The main visible section needs to include a natural-looking tunnel system, similar to the example image supplied. The tunnels should not look too geometric or artificial. I want: * Natural burrow-style tunnels. * Wider cave areas/chambers. * Larger voids for breeding, resting, or storing food. * Multiple routes up, down, left, and right. * Interconnecting tunnels. * Tunnels and chambers fully visible from the front through the Perspex. * Enough depth for ants to move comfortably. The tunnels should feel organic, but still printable and easy to clean where possible. ⸻ Side Connection System The design needs interchangeable side sections on both sides. These side sections should allow the user to either: 1. Connect multiple ant farm units together, or 2. Block the side opening if only using one unit. So I need: * Left and right side connection points. * Removable connector parts. * Removable blanking/blocking parts. * Secure fitting using magnets, screws, or a simple mechanical slot system. * The ability to expand the ant farm in the future by adding more printed units. ⸻ Foraging Area The design needs a foraging area built into it. This should be separate from the main tunnel section but connected so ants can access it. The foraging area needs to be large enough for: * Ants to explore. * Food to be placed inside. * Easy access for maintenance. * Good visibility. ⸻ Water / Sweet Water Area The model also needs a dedicated area large enough to place water or sweet water. This could be designed as: * A small removable tray area. * A recess for a small test tube/water tube. * A space to place a small feeding dish. I am open to suggestions on the best option, as long as it is practical, safe for ants, and easy to refill. ⸻ Printing Requirements The model must be designed for FDM 3D printing. Please design with the following in mind: * Printable on a standard large-format 3D printer. * Strong walls. * Minimal supports where possible. * Sensible tolerances for Perspex, magnets, screws, and connectors. * Parts should be split if needed to make printing easier. * The design should not rely on very fragile details. * Wall-mounted strength is important. Ideally, I would like files supplied in: * STL * STEP, if possible * Separate files for the main body, side connectors, blanking plates, and any removable parts ⸻ Style Reference I have attached an image showing the style I like. The tunnel system should be visible from the front and have a natural cave/burrow look, rather than straight lines or basic grids. I want the final design to look clean, modern, and functional, while still feeling like a natural ant habitat. ⸻ Final Deliverables Please provide: * Full 3D printable model files. * Separate printable parts where needed. * A version with the A4 Perspex recess. * Side connector pieces. * Side blanking/blocking pieces. * Magnet recesses. * M3 screw holes for the Perspex. * Wall mounting points. * Any notes on print orientation and assembly. ⸻ Important Notes The design must be practical, not just visually nice. This will be printed and used, so tolerances, strength, Perspex fitting, wall mounting, and ant access all matter. Please include examples of previous 3D printable product designs or functional models you have created. Designs for enclosures, terrariums, aquariums, modular systems, or mechanical parts would be helpful.
