Application development

@mrresearcher99

Hello, I’ve reviewed your requirements for an Access Control & Attendance Management System and can deliver a secure, scalable, and enterprise-grade solution. The platform will include user & device management, real-time monitoring, shift & attendance tracking, alerts via SMS/WhatsApp/Email, audit logs, and role-based dashboards. We’ll integrate with biometric devices (Hikvision, Dahua, ESSL, Matrix, Biomax) and provide Excel/API-based imports & exports. Built using a secure architecture with AES-256 encryption, TLS 1.2+, and a responsive web interface, the solution will also support future phases like visitor management, mobile apps, and AI-based anomaly detection. Could you confirm: Preferred deployment — cloud or on-premises? Existing biometric devices & APIs? Do you want the visitor module in Phase 1 or later? Let's discuss timelines and milestones. Best Regards, Bhargav.

Hello, I can build a centralized access control management tool where all devices (doors, gates, biometric readers, etc.) can be monitored and controlled from a single dashboard. The platform will include role-based access, device status monitoring, logs of all entry/exit events, and the ability to add/remove users or change permissions in real time. The system can be web-based for central management, with APIs to integrate various hardware vendors. Questions: – Which type of access control devices should the system support first (RFID, biometric, smart locks)? – Do you already have APIs/SDKs from the device vendors, or should I help identify integration methods? – Should the system support multi-site/device grouping (e.g., multiple buildings) from the start?

Thanks and Best regards, Kamran.

@techsty2014

Hello, Building a centralized tool for managing access control devices is a smart approach to streamline security and simplify administration. I can develop a secure, user-friendly application that consolidates control of all access devices into a single platform, enabling real-time monitoring, centralized permissions management, and efficient access policy enforcement. Questions: – Are there specific types or brands of access control devices this system needs to integrate with? – Do you require features like real-time alerts, reporting, or role-based access within the tool? – Should the system be cloud-based for remote management or on-premises for local control? I am a TOP Rated Freelancer, and you can check my reviews here as well: https://www.freelancer.com/u/techsty2014 Looking forward to potentially working together on this project.

Hello there, I can build your access-control platform with full user/device management, real-time device monitoring, punch and attendance exports (Excel/API/DB link), bulk user/device mapping, audit logs, configurable alerts (email/SMS/WhatsApp), role-based dashboards, licensing & backup workflows, and optional visitor management, mobile credentials, and AI-driven reports — designed for on-prem or hybrid deployments and compatible with common device makes. I have 11 years of experience delivering secure, enterprise-grade systems with complex integrations, reporting, and device ecosystems. To proceed: 1. Which deployment model do you prefer first — on-prem, cloud, or hybrid — and which RDBMS should we target (SQL Server or PostgreSQL)? 2. Can you confirm the exact device models/SDKs to support initially (Hikvision, Dahua, ESSL, Matrix, Biomax or others) and whether you have existing device/API docs? I can share relevant samples and provide a timeline and estimate after reviewing your device docs and any existing system. Best regards.

Hello! As per your project post, you’re looking to build a Windows and Android-compatible program that automates tennis court bookings on th.gametime.net. The goal is to streamline the reservation process by handling automatic login, scheduled bookings, court preferences, and smart notifications to ensure users secure their desired courts with minimal manual effort. I'M GLAD TO SAY THAT I HAVE ALREADY DEVELOPED TENNIS COURT BOOKING WEB & APP SO I HAVE EXPERIENCE IN THIS PROJECT. I specialize in automation software, cross-platform app development (Android + Windows), and API/web scraping solutions. My experience includes building auto-login systems, scheduled task runners, and real-time notification workflows that reliably interact with third-party booking platforms while maintaining security and performance. My focus will be on delivering a robust, user-friendly booking automation tool that allows input of date, time, players, and preferred courts, executes scheduled bookings at precise times (8am for courts opening at 12am), and notifies users intelligently if the preferred slot is unavailable ensuring a smooth, efficient court reservation experience. Let’s connect and build a seamless, automated tennis court booking system tailored to your needs. Best regards, Nikita Gupta

@ralphyh

Hi, I am a senior Python (Django, Flask) developer with 10 years of total experience. I love the API-first paradigm with JS frameworks like React.js, Angular.js, or Vue.js on the frontend, and Python for the backend for complex interface apps. I can develop mobile applications using React Native and Cordova (Ionic/PhoneGap). One of my projects is an AWS cloud-based Video-On-demand streaming platform with microservices architecture for Cisco. I have done some pretty big projects with Python. The most recent ones were an employee testing platform for a company and a website for a scientific society with a fairly complex rating and recommendation system. I have a pretty decent amount of projects in my portfolio. I am happy to tell more during a video call.

For a project of this scale and nature, which requires an on-premises deployment and a relational database, I propose the following technology stack: Backend: A robust and secure framework like .NET Core (C#) or Java Spring. These frameworks are ideal for building mission-critical enterprise applications that need to handle complex business logic and secure API endpoints. Frontend: A modern JavaScript framework such as React or Angular to create a responsive, professional, and intuitive user interface as requested. Database: I will use PostgreSQL or SQL Server, as specified, to ensure data integrity and provide a scalable foundation for your data. Real-time Communication: For the real-time device monitoring and event tracking you require, I will implement WebSockets to handle a constant flow of data from devices to the web interface. This stack is known for its reliability and performance, ensuring your system can grow from small sites to an enterprise scale.
