Project Overview & Vision
The professional tech upskilling and certification sector requires flawless digital media delivery. Students on mobile networks require instant, zero-buffer video playback, while education institutions must protect proprietary high-value course content against link scraping, unauthorized sharing, and screen recording.
TechyArts was commissioned to architect and deploy the Netra Learning System (NLS) — a proprietary, high-throughput Learning Management System capable of delivering secure, adaptive bitrate HLS video streaming, automated multi-tier certification pipelines, and zero-latency analytics tracking for 50,000+ concurrent learners.
We transformed a bottlenecked, monolithic system into a resilient cloud infrastructure with 99.98% playback reliability, zero video piracy leakage, sub-180ms Time-To-First-Byte, and automated Cashfree installment reconciliations.
"In online education, video buffering kills student momentum and video piracy destroys business value. TechyArts eliminated both. Their adaptive HLS proxy and dynamic forensic watermarking allowed us to scale to over 50,000 students with absolute peace of mind."

Streaming Latency & Video Piracy Vulnerabilities
Direct cloud storage delivery and legacy video players created systemic scaling friction and intellectual property risks:
Video Latency & Cross-Origin (CORS) Drops
Direct cloud storage delivery caused severe buffering, erratic network throttling on mobile 4G/5G connections, and frequent CORS 403 Forbidden drops across mobile browsers.
IP Vulnerability & Video Piracy Leaks
Unprotected raw video URLs risked screen recording, link scraping, and unauthorized redistribution, lacking session-bound cryptographic protection.
Fragmented Cross-Device WebKit Rendering
Inconsistent mobile WebKit rendering between iOS Safari and Android Chrome caused viewport letterboxing, broken fullscreen states, and displaced UI on notched displays.
Payment Reconciliation & Enrollment Delays
Split-installment payment lifecycles and manual course enrollments created high support overhead and drop-offs during high-volume cohort onboarding.
Decoupled Cloud-Native Video & Learning Architecture
TechyArts engineered a decoupled, cloud-native architecture optimized for high throughput, cryptographic security, and low-latency mobile rendering:
Zero-Trust Media Delivery Proxy
Constructed a cryptographic streaming proxy (/api/video/hls-stream/) with dynamic JWT token signing, origin verification, and automated S3 path traversal shielding.
Dual-Mode HLS Video Engine with Auto-Healing
Integrated client-side HLS.js paired with native WebKit fallbacks, equipped with auto-healing error interceptors dynamically switching streams upon network variance.
Edge-to-Edge Notch-Aware Responsive Canvas
Implemented modern viewport controls (viewport-fit=cover, 100dvh, CSS pseudo-fullscreen abstractions) guaranteeing notch-aware, zero-gap video playback.
Automated Two-Tier Installment & Payment Engine
Full Cashfree SDK and webhook integration powering instant enrollment unlock, installment milestone alerts, and dynamic coupon validation.

Strategic Engineering Pillars
How TechyArts engineered resilient multi-platform systems to solve complex operational challenges, lower cloud infrastructure costs, and deliver seamless user experiences.
Adaptive Bitrate HLS Media Pipeline
AWS MediaConvert · Multi-Rendition HLS (1080p to 360p)
Automated media ingestion pipeline converting raw MP4 masters into multi-rendition HLS (1080p, 720p, 480p, 360p) with chunked .ts segments and synchronized master playlists. Dynamically adjusts resolution based on client network bandwidth, dropping TTFB to under 180ms.
Active Forensic Session Watermarking
Dynamic Canvas Overlay · Cryptographic Audit Trails
Client-rendered dynamic canvas watermarks displaying randomized, moving overlays containing student ID, session timestamps, and encrypted audit trails to completely neutralize screen capture theft and unauthorized course sharing.
Smart Orientation-Aware Video Stage
Gyroscope Detection · Zero-Gap Fullscreen Scaling
Orientation-aware video player engine that auto-detects landscape transitions on mobile devices, seamlessly scaling into fixed, zero-gap full screen without page layout displacement or mobile WebKit letterboxing.
Automated Installments & Auto-Enrollment
Cashfree Payment Gateway API · Webhook Reconciliation
Engineered an automated split-installment payment lifecycle with Cashfree webhooks, instantly provisioning student access upon transaction confirmation, tracking milestone dues, and auto-disabling overdue access with zero manual intervention.
Cryptographic Certification & QR Verification
90% Watch-Time Milestone · Instant Public QR Audits
Rules-driven certificate issuance triggered only when verified video watch-time exceeds 90% and all module milestones are completed, generating tamper-proof digital certificates with unique QR codes for instant external verification by employers.
