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.

AI SaaS architect, senior full-stack developer, AI developer, and automation expert. I build LLM/RAG systems, AI agents, agentic workflows, ChatGPT and OpenAI integrations, and production SaaS platforms that ship in 2–4 weeks. No prototypes. No disappearing after handoff.
Founders and CTOs don't call me first. They call after the offshore agency delivered a half-working prototype. After the generalist ran out of depth. When the stakes are too high to get it wrong again — that's when they call me.
I work like a technical co-founder: I understand your business problem as clearly as the technical one. No account-manager layer, no junior handoff. You work directly with senior engineering across architecture, implementation, deployment, and the post-launch fixes that real systems always need.
Over 70% of clients come back for another engagement — because trust is easier to earn through delivery than through proposals.
📈 PRODUCTION RESULTS
✅ n8n + GPT-4 replaced a 12-person workflow — 10,000+ records/day at 99.2% accuracy, saving $380K/year. Shipped in 3 weeks.
✅ Flutter + Node.js fintech SaaS processing $2M+/month — 3 years ongoing, same client.
✅ React + LangChain legal AI tool — cut attorney document review time by 73%.
✅ Next.js + Supabase multi-tenant SaaS with Stripe — zero to $45K MRR in 5 months.
✅ Cross-platform Flutter app — 50,000+ active users across iOS, Android, and desktop.
✅ OCR + GPT-4 + LangChain document pipeline for logistics — 8x throughput, same headcount.
✅ HIPAA-compliant clinical RAG system — delivered in 5 weeks.
✅ Loan-decision latency cut from 4.2s to 280ms for a Series-A lender.
✅ Author of ngx-mask — 2M+ monthly npm downloads, used in fintech, healthcare, and enterprise SaaS worldwide.
🛠️ WHAT I BUILD
→ LLM/RAG features — OpenAI, Claude, Gemini, ChatGPT, RAG pipelines, AI agents, multi-agent systems, agentic workflows, semantic search, vector databases, embeddings. Evals, latency, observability, fallback paths included.
→ AI SaaS platforms, MVPs & PoCs — multi-tenant architecture, Stripe billing, RBAC, onboarding, analytics, CI/CD. From validated PoC to production-grade platform without rebuilding from scratch.
→ AI workflow automation — n8n + LLM pipelines replacing manual ops, copy-paste, spreadsheet cleanup, CRM updates. Human-in-the-loop review flows. 10,000+ records/day at 99%+ accuracy.

I help founders and teams build and ship reliable production ready apps quickly.
Most projects I work on don’t start from scratch they’re already in progress, but stuck. Maybe the MVP works but feels fragile, the code is messy, or you’re not confident putting real users on it yet.
That’s where I come in.
I focus on moving things forward fast, while making sure what we build is stable, maintainable, and ready for real use not just demos.
With 6+ years across startups, agencies, and public sector teams, I’m comfortable jumping in at any stage and bringing structure, clarity, and momentum.
What you can expect working with me:
• Fast turnaround without cutting corners
• Clear communication and consistent progress
• Clean, maintainable code that won’t cause problems later
• Thoughtful UX that actually improves usability
• A clear path from MVP → real product
I work across both AI driven builds and traditional full stack development, so whether you’re starting from an idea, an AI generated prototype, or an existing app, I can help you move forward with confidence.
If you need to build or ship something quickly and want it done properly feel free to reach out. Happy to take a look and point you in the right direction.

Starting a new mobile project and want to ensure it’s built right from day one? Or do you have an existing application that needs a professional architectural overhaul to handle growth?
Most mobile MVPs hit a ceiling because they lack a scalable foundation. I specialize in helping founders and businesses navigate the critical transition from "initial idea" to a high-performance, production-ready application. Whether you are starting with a blank canvas or looking to stabilize an existing codebase, I ensure your mobile presence is secure, responsive, and built to last.
I don't just "build apps"; I architect mobile solutions. I prioritize clean, typed, and efficient Dart engineering to ensure your product isn't a "house of cards" that breaks the moment you gain traction.
👤 Why Partner With Me?
- I act as a Technical Partner who understands that code is a means to a business end. With 5+ years of experience in mobile leadership, I treat your budget and timeline with the same respect I treat my own.
- Strategic Planning: I don't just ask "How do I code this?" I ask, "Is this the most efficient way to solve the business problem?" I help you prioritize the core features that drive value and revenue.
- Architectural Foresight: I have the experience to spot potential bottlenecks—like poor state management or inefficient API layers—long before they become expensive disasters.
- Clear Communication: I bridge the gap between "Tech" and "Business." I explain complex architectural decisions in plain English so you always maintain full control over your product roadmap.
🤝 Who Am I a Good Fit For?
- Founders Starting from Scratch: You want a solid foundation from Day 1 so you never have to "rebuild from the ground up" later.
- Businesses Improving Existing Apps: You have a working app but need a professional to refactor the core for better stability, speed, or security.
- Non-Technical Visionaries: You need a partner to own the technical roadmap and manage the complexities of the App Store and Google Play.
- Long-Term Thinkers: You value reliability, clean architecture, and a partner who will tell you "no" if a feature isn't technically feasible.
Ready to start your next project or professionalize your existing one? Let’s discuss your technical roadmap and build something that scales.
