As a forward-thinking Senior Engineer and Team Leader with over two decades of experience, I work as a full stack developer specializing in Video Streaming and real-time communication solutions based on WebRTC. I combine strong architecture thinking with hands-on delivery, acting both as a technical leader and a practical full stack web developer who understands real product needs and builds scalable WebRTC-powered systems.
Today, my focus as a full stack developer includes the strategic application of advanced AI technologies alongside WebRTC-based real-time communication platforms. I actively work with OpenAI APIs, Whisper for speech recognition, LLaMA2 for open-source large language models, and LangChain for building AI-driven workflows. This positions me as a full stack developer AI who can integrate intelligence directly into real-world WebRTC video and streaming products.
Throughout my career as a full stack developer, I’ve contributed to Telemedicine, Online Education, and Real-time Entertainment by building WebRTC-powered communication platforms. I’ve led teams delivering webinar platforms, live chat systems, and complex real-time applications, acting both as a senior web developer and system architect who ensures scalability, security, and long-term maintainability for WebRTC infrastructures.
In AI-focused projects, I operate as a full stack developer who bridges data, logic, and user experience inside WebRTC-enabled applications. My team and I integrate conversational AI, speech-to-text, and knowledge-driven systems using OpenAI, Whisper, and LLaMA2. With LangChain, we design intelligent pipelines that automate workflows and data processing, enhancing WebRTC communication platforms with AI-driven capabilities.
WebRTC remains a core part of my work as a full stack developer, especially for building high-performance real-time systems. We design everything from low-latency WebRTC infrastructure to complete applications, delivering solutions that work seamlessly across web and mobile. This includes building scalable video streaming app architectures capable of handling thousands of concurrent users through WebRTC.
As a full stack developer, I also provide consulting and development services across North America and Europe, helping companies design and build WebRTC-based video communication platforms. I work with companies in Entertainment, E-Learning, Healthcare, and Finance. Depending on project needs, I act as a React developer, Wordpress developer, or mobile app developer while implementing scalable WebRTC solutions.
Our services as a full stack developer team include system architecture, UI/UX design, and custom development of WebRTC streaming and real-time communication platforms. We build modern interfaces, robust back-ends, and real-time systems, including secure WebRTC video stream delivery for live and on-demand use cases.
We have worked with most of the major Webinar and Online Education platforms on the market, delivering solutions as a full stack developer team that understands both the business and technical sides of WebRTC video streaming products. We frequently modernize existing platforms and migrate legacy systems to scalable cloud-based architectures built around WebRTC technologies.
As a full stack developer, I’ve led the creation of webinar systems, live chat apps, WebRTC video conferencing platforms, real-time video auctions, messengers, e-learning platforms, telemedicine solutions, dating apps, Twitch-like platforms, TikTok-style apps, VoD systems, and live shopping platforms. Many of these solutions rely on modern stacks including full stack developer React and full stack Lavarel approaches integrated with WebRTC.
Beyond development, I support clients as a full stack developer with load testing and performance optimization for large-scale WebRTC streaming systems. My background across front-end, back-end, databases, and cloud platforms allows me to lead projects end-to-end and deliver reliable, production-ready WebRTC platforms.
I invite you to collaborate with me as a full stack developer who understands AI, WebRTC, and scalable real-time product development. Together, we can build innovative WebRTC-powered solutions that align with your business goals and grow with your users.

Node.js and React is my love but React Native is my passion
Hi there!
I'm a senior Full Stack Developer React Node.js with 7+ years building web and mobile apps end to end, from the database up to pixel-perfect interfaces. I live in the JavaScript and TypeScript ecosystem and pair a React and Next.js frontend with a Node.js backend to ship scalable web applications and SaaS platforms. Most of my web app development and mobile app development work involves heavy third-party API integration. I've delivered everything from data-heavy dashboards to cross-platform React Native apps.
🏆 7+ years as a Full Stack Developer React Node.js & React Native Mobile Developer
🏆 $100K+ earned on Upwork as Full Stack developer at 100% Job Success Score with Top Rated status
🏆 3,000+ hours as a full stack web developer & React Native mobile developer across 10+ delivered projects
🏆 10+ web app development and mobile app development projects delivered as a Full Stack Developer
I'M USUALLY BROUGHT INTO PROJECTS THAT NEED:
- a Full Stack Developer who can take a feature from the database all the way to the UI without handing it off
- a Backend Developer or Backend Engineer who has kept real production systems running, not just demos
- a React Native Mobile Developer to ship a single codebase to both iOS and Android with proper cross-platform mobile app development
- a Front End Developer or React developer who gets the React and Next.js UI pixel-perfect
- a SaaS Developer who builds for the version you'll have in two years, not just launch day
- an MVP developer whose MVPs are made to grow into real SaaS products
- a web app developer for web applications where the workflows and business rules are the hard part
BACKEND IS WHERE I SPEND MOST OF MY TIME. AS A BACKEND DEVELOPER AND NODE.JS DEVELOPER, THAT MEANS:
- designing and shipping backend services in Node.js and TypeScript with Nest.js and Express, the full stack developer react node engine behind most of my progressive web applications
- owning data in PostgreSQL end to end, from schema to migrations, plus Redis, MongoDB and DynamoDB where they fit
- treating API integration as core work, the kind of api developer territory that covers REST APIs
IN A REACT NATIVE MOBILE DEVELOPER ROLE, I CAN TAKE CARE OF:
- shipping a single React Native codebase to iOS and Android, real cross-platform mobile app development instead of two separate native teams
- setting up React Native with Expo, navigation, push notifications and React Native Firebase for auth, storage and messaging
- adding real-time features such as chat and calls with React Native WebRTC, plus offline support and clean mobile app design
MY STRONG SKILLS INCLUDE:
- Programming Languages: Javascript (ES5+) Typescript C# Solidity
- Technologies: Node.js HTML5/CSS3 React React Native Smart Contracts (Ethereum) Ether.js
- Frameworks: Express.js Nest.js Next.js Koa.js .NET Core React Native (Expo)
- Libraries: Bootstrap Moment.js RxJs Nodemailer Redux Redux-toolkit Axios Sequelize TypeORM Prisma Dapper Entity Framework AutoMapper luxon SocketIO JsonWebToken Storybook
- DBMS: MySQL PostgreSQL MongoDB FireBase SQlite3 DynamoDB Redis CosmoDB Neo4j
- AI Tools I can use: Cursor GitHub Copilot Codex Claude
A note on honesty, because it saves everyone time. I'm not your python developer, php javascript or java backend hire. I won't claim full stack developer php, python full stack developer, ruby on rails, wordpress full stack work as my own. A dedicated wordpress developer, shopify developer or flutter developer is the better call.
I'm always open to new challenges, whether you need a full stack developer, a react native developer or just an extra senior pair of hands on a web app or mobile app development project.
☎️ Feel free to contact me here anytime.
