These qualities were integral in my work as a lecturer and researcher-credentials that are present in every aspect of my work as a developer today.

@technologiesit

Drawing from my extensive experience as a seasoned Full Stack Developer and Digital Solutions Expert, I strongly believe that my skill set aligns perfectly with the scope of your project. My 8+ years working with Backend and Full Stack Development have endowed me with a deep understanding of Node.js, TypeScript, API implementation, websockets, webhooks – among others – just as you're looking for. One of the things I bring to the table is the ability to work on an existing production codebase. I understand this can be a challenge and I am more than capable of translating that into opportunity. Moreover, having had success with over 100 projects before, I am confident about my ability to provide clean-cut solutions with clear communication and faster delivery. Not least, reliability matters greatly to me. Being an individual freelancer fully committed to long-term relationships suits your need for somebody who’s able to own tasks and drive them independently. The combination of my strong experience in scalable backend systems paired with a demonstrated ability to optimize performance makes me an optimal fit for reducing bugs, improving code quality and overall system design and architecture – all vital aspects of your CPaaS project. Let's turn your vision into reality together!

@jagratip3

Hello!, I’ve carefully reviewed your requirements and understand you're looking for a long-term technical partner, not just someone to complete isolated tasks. Your CPaaS platform requires a developer who can work confidently with production systems, improve architecture, optimize performance, and build reliable event-driven services. With strong experience in Node.js, TypeScript, Express, PostgreSQL, Redis, WebSockets, REST APIs, queues (BullMQ), and microservice architecture, I can help debug complex issues, optimize real-time messaging, improve scalability, and implement new features while maintaining clean, maintainable code. I’m comfortable working independently, reviewing existing codebases, identifying bottlenecks, and proposing practical architectural improvements rather than simply following instructions. A few questions: How many microservices are currently in production? Do you already have CI/CD and staging environments? Which area is your highest priority—performance, messaging reliability, or new features? I’m interested in building a long-term collaboration and delivering high-quality, milestone-based work that keeps your platform stable, scalable, and ready for growth.

@albertc1996

I understand you need an individual developer who can work task-by-task on a live microservice-based messaging system covering SMS, WhatsApp, email, queues, webhooks, WebSockets, polling, and CRM integrations. I’m a full-stack developer with 8+ years of experience building backend systems with Node.js, TypeScript, Express, PostgreSQL, Redis, queues, REST APIs, WebSockets, and scalable event-driven services. I’m also comfortable working inside existing production codebases, finding root causes, improving performance, reducing bugs, and suggesting architectural improvements when something can be made cleaner or more reliable. Your stack aligns closely with my experience: Node.js, TypeScript, PostgreSQL, Redis/DragonflyDB, BullMQ, REST APIs, WebSockets, React, Tailwind, and modern frontend tooling. A couple of questions: how are your services currently separated—by channel, tenant, or event workflow? Also, do you already have monitoring/logging in place for queue failures, webhook retries, and message delivery states? I’d be happy to start with a focused milestone so you can evaluate my code quality, communication, and problem-solving style.
