Looking for a FULL STACK DEV TEAM - MONTHLY PAY WHO WILL HANDLE THE FOLLOWING : ( this is to upkeep everything fix any issues with loading etc and making it better , this will be a 24/7 thing 30 days at a time ) so its month to month , not in 7 days or nothing like that . Its a full on job that will be paid monthly or bi weekly . We require an experienced development team to manage, maintain, improve and support our existing systems and future projects. Below is an overview of our current structure and requirements. Developers should review this structure and implementation as part of understanding the project setup and future requirements. Admin Portal We have an internal admin portal that manages our main website and multiple country based subdomains. All customer orders are received here and processed through different stages depending on the destination country. Each country has its own rules, workflows, and status tracking, such as: Awaiting customer documents Awaiting government response Processed/completed applications Manual review stages Chargeback & Dispute Portal We have a chargeback management portal used to search customer transactions and generate defence packs for disputes and chargebacks. The system stores important evidence such as: Customer IP address Device/browser information Download history of documents Email delivery/open history Communication logs This information is used to support disputes with payment processors and banks. Payment Gateway Management Portal We have a gateway management system that allows us to quickly switch merchant accounts/gateways across all or selected subdomains. This is important because some merchant accounts may reach processing limits, require rotation, or need temporary replacement. The process must be fast and reliable with minimal downtime. Email Management Portal We require a centralized email portal where staff can easily monitor incoming emails across accounts, quickly open conversations, and respond efficiently. Previously, emails had to be opened individually, which slowed response times. Server Infrastructure Ongoing server management, maintenance, monitoring, optimization, and troubleshooting are required to ensure high uptime and fast performance. Cloudflare Management Configuration, optimization, maintenance, and troubleshooting of Cloudflare services, including DNS, caching, security, WAF, and performance settings. Third Party Services Installation, integration, maintenance, and troubleshooting of third-party systems such as: Email services SMS providers Telephone/VoIP systems APIs and external integrations Website Development & Maintenance Development and maintenance of our websites and subdomains, including: Bug fixes Performance improvements UI/UX updates Troubleshooting issues affecting users Custom Application Development We require custom-built applications and workflows. These are not copies of government websites but internally developed systems that integrate with our services and processes. SEO & Performance Ongoing work is required to improve: Website speed Core Web Vitals SEO structure Mobile performance Conversion optimization Google Compliance We require ongoing monitoring and adjustments to ensure websites remain compliant with Google policies, including ad compliance, site quality, and technical requirements. Security & Data Compliance Site security and compliance are extremely important. This includes: Security monitoring Protection against attacks/exploits Data protection compliance Privacy and data handling requirements Mobile App Development We are currently building a mobile application which needs to function similarly to our existing website and integrate with our current systems and workflows. Developer Availability & Support We require developers to be available on demand for urgent issues, troubleshooting, updates, and ongoing support when needed. JavaScript Reliability Issues One of our major ongoing issues is JavaScript failures on the website which can cause forms or pages to stop working, resulting in lost customers. We need a more stable solution with proper error handling, monitoring, failover behaviour, and testing processes to prevent these issues from affecting users.

Hi - Elias here from Miami. The real challenge in full stack development lies in maintaining a seamless integration between frontend and backend while ensuring scalability and performance under load. Many projects falter when they overlook the complexity of state management, API design, and data handling, leading to increased latency or system failures. Common pitfalls include tight coupling between components, which can hinder flexibility and complicate future updates. Performance issues often arise from inefficient database queries or inadequate caching strategies, impacting user experience and system reliability. My approach would involve a microservices architecture, allowing for independent scaling of components based on load. Key to this is a robust API layer that can handle asynchronous requests effectively, minimizing blocking calls. Implementing thorough monitoring will help us catch edge cases and performance bottlenecks early. We should prioritize decisions around the database technology and schema design to ensure it can handle expected growth and optimize for read/write patterns. Early choices regarding state management in the frontend will also be crucial for maintaining a responsive user interface. What specific scalability requirements do you foresee for the user base? Looking forward to collaborating.

Hi, you’re not looking for a simple website maintainer here; this is a live multi-portal operations environment with payment routing, dispute evidence, subdomain workflow control, and customer-facing reliability issues. The real engineering risk is uncontrolled coupling between frontend flows, portal logic, and operational integrations, which is how small JS failures turn into lost orders and hard-to-debug production incidents. I’ve worked on live systems where the first step is understanding failure paths before adding more features. I usually structure this kind of engagement around codebase review, incident pattern analysis, and isolating the highest-risk surfaces first, especially around forms, state transitions, and admin-controlled behavior. The closest matches in my background are Custom Feature Development & Integration and Squarespace Checkout Streamlining for Meal Service -- 2. Both involved stepping into existing systems, tightening user flows, reducing breakage, and improving maintainability without disrupting live operations. I’d recommend separating frontend reliability, portal workflow logic, and integration control points so failures are observable and contained. For the JS issues specifically, I’d focus on error capture, recovery behavior, test coverage around critical conversion paths, and safer rollout patterns across subdomains. Thanks, Hercules

Hi, I’ve reviewed your project and I’d love to support you with a dedicated full-stack development team for ongoing monthly maintenance, optimisation, and 24/7 system support across your admin portal, chargeback system, payment gateways, email infrastructure, and multi-subdomain environment. I’ll start by auditing your current architecture across backend, frontend, Cloudflare, and server setup, then stabilise existing JavaScript issues, improve error handling and monitoring, and set up a structured maintenance + deployment workflow. After that, we’ll move into continuous improvements, security hardening, performance optimisation, and feature development in a sprint-based monthly cycle. I understand this is a mission-critical system where uptime, payment reliability, and dispute data integrity directly impact business operations. A few quick questions: What is your current tech stack (Node, PHP, Laravel, etc.)? Are you using AWS, DigitalOcean, or dedicated servers? Do you already have CI/CD and monitoring tools in place? How many active users/transactions per day across systems? Do you want a dedicated team or shared on-call rotation model? All work will be handled first in a staging/backup environment before production changes. Budget and timeline are placeholders and will be structured into a monthly retainer based on scope and SLA. Best regards Kanwal U.
