🥇 Over 7 Years of Experience in Real-Time Applications, Healthcare Platforms, and AI-Driven Systems.
Hi 👋, I'm Fabian and thank you for visiting my profile.
I build secure, HIPAA-compliant telehealth platforms and AI-powered real-time video applications that handle thousands of concurrent patients and providers with ultra-low latency (<500ms).
I specialize in WebRTC, LiveKit, AI/ML integrations, and modern full-stack development, the exact stack modern healthcare apps need for virtual consultations, remote patient monitoring, and AI-driven clinical workflows.
Recent projects include:
✓ Built a HIPAA-compliant telehealth video platform handling 5,000+ daily patient consultations with WebRTC & LiveKit
✓ Created an AI-powered remote patient monitoring dashboard integrating real-time vitals streaming and LLM-based clinical summarization
✓ Developed a secure virtual care app with screen sharing (for medical imaging), EHR/EMR integration, and real-time AI medical transcription
I help health-tech startups and medical enterprises launch secure, scalable MVPs fast with production-ready, compliance-first infrastructure.
Healthcare & Real-Time Video (WebRTC/LiveKit)
• HIPAA-compliant Audio/Video streaming for telehealth
• LiveKit SFU integration for multi-party virtual care
• Secure screen sharing for medical imaging (DICOM viewer integration)
• Real-time chat, file sharing, and end-to-end encryption (E2EE)
• Low-latency optimization & cross-browser reliability for clinical use
AI & Full-Stack Healthcare Integrations
• AI Medical Transcription & Ambient Clinical Intelligence
• LLM integration for automated clinical note generation (SOAP notes)
• EHR/EMR integration (Epic, Cerner, HL7, FHIR standards)
• Full-Stack Development (React, Next.js, Node.js, Python, Go)
• Secure cloud infrastructure (AWS HIPAA, Azure, GCP)
WebRTC & AI Service Providers I Work With
• LiveKit
• Daily
• Twilio Video
• Agora
• Vonage (TokBox)
• OpenAI / Anthropic (LLMs)
• Deepgram / AWS Transcribe / Whisper (AI Voice/Text)
• Janus / mediasoup / Jitsi (self-hosted SFU/MCU for on-premise healthcare)
What I deliver:
• Telehealth & Virtual Care platforms (like Zoom for Healthcare / Doxy.me clones)
• AI-assisted clinical workflows & ambient scribing tools
• Remote Patient Monitoring (RPM) real-time dashboards
• Secure video recording, VOD, and compliance auditing pipelines
• End-to-end Full-Stack architecture with strict data privacy (PHI/PII)
• Integration of AI models into existing healthcare workflows
I am not an agency but a reliable and individual developer, I can start to work immediately and commit 40+ hours per week in your business time.
Kindly drop a message! Looking forward to making our cooperation a success! 🎯

WebRTC, FFmpeg, AI, OpenCV, Streamin – I fix real-time video apps and have since 2005. 13,485 hours, 14 projects, 100% Job Success. Zero abandoned. ⚡ 𝗙𝗿𝗲𝗲 𝗣𝗥𝗗. 𝗠𝗩𝗣 𝗶𝗻 𝟳-𝟭𝟰 𝗱𝗮𝘆𝘀. 𝗙𝗿𝗲𝗲 𝗰𝗼𝗱𝗲 𝗿𝗲𝘃𝗶𝗲𝘄 𝗼𝗿 𝟮-𝘄𝗲𝗲𝗸 𝘁𝗿𝗶𝗮𝗹 𝗼𝗻 𝗮𝗻 𝗲𝘅𝗶𝘀𝘁𝗶𝗻𝗴 𝗰𝗼𝗱𝗲𝗯𝗮𝘀𝗲.
Netflix, HBO, EA, Nokia, the World Bank, and Harvard trust platforms I've built. These clients don't give second chances. Mine work.
⚠️ Invite me to your job – I reply within 15 minutes.

→ Speed.Space – live production platform for Netflix, HBO, EA, and Apex Legends. Multi-stream switching, real-time collaboration, pro codec control. Used at Paris Fashion Week and Live Nation events. Zero downtime.
→ ShortKlips – video project management for Nokia and the World Bank. 200K+ monthly video views. Cut client project turnaround by 30%.
→ VirtualCr8tive – hybrid event platform for Harvard University and U.S. Vets.
→ CloudDoctors – HIPAA-compliant telehealth on WebRTC. Built from concept through multiple release cycles.
→ YUUALL – WebRTC platform built across multiple versions, long-term engagement.
𝗪𝗵𝗲𝗿𝗲 𝗜'𝗺 𝗦𝘁𝗿𝗼𝗻𝗴𝗲𝘀𝘁
– Pipeline latency – I profile FFmpeg filter graphs and cut processing time without losing quality.
– WebRTC under load – jitter buffer, codec mismatch, TURN/STUN. I find which one is yours fast.
– AI on live video – TensorFlow inference under 80ms; object and audio recognition on live feeds.
– FFmpeg deep work – custom filter graphs, muxing, hardware acceleration (NVENC, VAAPI, VideoToolbox).
– Scale & reliability – systems handling 600M+ call minutes a month, fixed at the architecture level.
𝗦𝗽𝗲𝗰-𝗙𝗶𝗿𝘀𝘁 𝗔𝗴𝗲𝗻𝘁𝗶𝗰 𝗘𝗻𝗴𝗶𝗻𝗲𝗲𝗿𝗶𝗻𝗴
I work spec-first, not vibe-first. I write the full spec and architecture before any code. Then I drive AI agents: developer, tester, analyst – against strict guardrails to produce production-grade code. The hard real-time work I handle or verify myself: WebRTC pipelines, sub-second latency, on-device ML. You get AI speed with the stability of a senior engineer, 4-10× faster than classic coding.
𝗛𝗼𝘄 𝗜 𝗪𝗼𝗿𝗸
You describe what's broken or what you're building. I send back a diagnosis: the problem, the fix, the cost. Not a sales call. Then we scope the work together before either of us commits. My estimates average ~10% off actuals. I validate before building and run staged QA on every release.
𝗛𝗼𝘄 𝗬𝗼𝘂 𝗖𝗮𝗻 𝗪𝗼𝗿𝗸 𝗪𝗶𝘁𝗵 𝗠𝗲
1. Build from scratch – real-time video, AI, or streaming, end-to-end.
2. Drop in on your team – I take the hard video, AI, or WebRTC modules.
3. Rescue and modernize – fix slow or unstable platforms and ship to production.
I work inside the Fora Soft team – 51-200 engineers. If your project grows, a PM, QA, and more developers are already there. No solo freelancer who vanishes when scope expands.

I build production-grade audio plugins, real-time 3D tools, and AI-powered software for startups and studios from C++/JUCE DSP engines to WebGL configurators and AI pipelines, shipped end to end.
My strength is combining rigorous engineering with design precision: the result is software that's not just functional, but fast, polished, and easy to use.
Core skills:
Audio/DSP : JUCE, C++23, VST3/AU/CLAP, FFmpeg, custom plugin GUIs
3D/XR : Three.js, WebGL, WebXR, Unity, Unreal Engine, OpenGL, Blender
AI/ML : Python, PyTorch, OpenCV, RAG, FastAPI, automation workflows
Full-Stack : Next.js, React, Electron, Node.js, Cloudflare-native architectures (Workers, D1, R2) for SaaS products and creative tools
I work best as an ongoing technical partner on retainer or for multi-phase builds for teams shipping complex creative or AI-powered software. Happy to scope shorter projects too, but I do my best work when I'm involved from architecture through launch.

🎯 I turn repetitive video production into automated pipelines that run without anyone touching them — subtitling, encoding, and template-driven video generation for media companies, broadcasters, and content creators.
⭐ Top Rated · 100% Job Success · 54 projects delivered · 5.0 · 13+ years in broadcast engineering
Using FFmpeg, Python, Node.js, React, Remotion, After Effects scripting, Whisper AI, and n8n, I've built high-throughput FFmpeg pipelines (CPU & GPU — NVENC/CUDA), API-driven After Effects rendering systems, and AI-powered speech-to-text captioning workflows. If it's a repetitive video task, I turn it into a script that scales.
▸ WHAT I AUTOMATE FOR YOU
• After Effects — JSX/ExtendScript, aerender pipelines, template-driven video generation
• AE → Remotion pipelines — convert After Effects templates into server-side React/Remotion renders (props for text, image, video, alpha overlays; multi-language output)
• FFmpeg — encoding, compression, watermarking, format conversion (NVENC/CUDA)
• Video generation APIs — automated rendering pipelines & queue systems (Remotion, Node.js, FastAPI)
• Subtitles & captions — generate, convert, burn-in (SRT, WebVTT) powered by Whisper AI
• n8n workflows — connecting your tools into one hands-off automated flow
• Live production — OBS/vMix consulting, ATEM switching, Blackmagic DeckLink integration
• Playout & ingest — SDI and file-based/IP workflows
• Media asset management — LTO archiving & long-term storage
▸ WHY CLIENTS KEEP HIRING ME
• 13+ years in live broadcast — I've shipped under real deadlines, not just in theory
• Led a team of 13 engineers — I document properly and deliver production-ready systems
• Performance-obsessed: GPU acceleration, parallel processing, efficient encoding
• I speak both "editor" and "engineer" — bridging creative workflows and backend automation
