Online Course Platform Development

Video lesson upload and streaming with adaptive bitrate (ABR) delivery via Mux or Wistia -- both transcode uploaded source files into multiple quality renditions (1080p, 720p, 480p, 360p) and deliver via HLS (HTTP Live Streaming) so each learner's player automatically selects the rendition that matches their available bandwidth. Learners on a 3G connection get continuous playback at lower resolution; learners on broadband get the full-quality rendition without buffering delays.

Video transcription using AWS Transcribe or Deepgram generates accurate time-coded captions automatically on upload. Transcripts are indexed for search so learners can find specific content by keyword within a lesson, and captions are served as WebVTT files for WCAG 2.1 AA accessibility compliance. Chapter markers with thumbnail previews let learners navigate directly to the section they need. SCORM 1.2 and SCORM 2004 content package import accepts content authored in Articulate Storyline, Adobe Captivate, or any SCORM-compliant authoring tool, embedding the interactive content within the course player. Quiz and assessment builder supports multiple-choice, true/false, short-answer, and matching question types at the lesson, module, and course level. Content drip scheduling releases lessons on a fixed calendar schedule or after a defined number of days since enrolment. Bulk content import from another platform handles video migration, quiz data, and learner progress records as part of a platform switch project.

Self-enrolment for open courses and cohort-based enrolment for live cohort programmes with fixed start dates and capacity limits. Individual progress tracking per lesson and module shows each learner exactly where they are in each course and what remains to complete. Progress data is stored via xAPI (Experience API, also known as Tin Can) learning records to a Learning Record Store (LRS), giving organisations a portable, standards-compliant record of learner activity that can be queried across platforms and integrated with corporate HR or LMS systems using the LRS REST API.

LTI 1.3 (Learning Tools Interoperability) integration allows third-party tools -- interactive simulations, virtual labs, plagiarism checkers, proctoring services -- to be embedded directly within course content and pass completion and grade data back to the platform without the learner leaving the course environment. LTI 1.3 replaces LTI 1.1 with a more secure OAuth 2.0 and JSON Web Token (JWT) authentication flow. Resumable video position saves exactly where a learner stopped, synced across devices, so a learner who watches 40% of a lesson on mobile can resume at the same point on desktop. Completion certificates fire automatically on course completion with no manual admin trigger. The learner dashboard provides a clear view of active courses, progress percentages, and earned credentials with download and share links.

Stripe integration handles one-time course purchases, recurring subscription access via Stripe Billing with configurable billing intervals, and payment plan models (for example, three monthly instalments for a $900 course) -- all without a platform transaction fee on top of Stripe's processing cost. PayPal is integrated as an alternative checkout method for markets where it is the preferred payment instrument.

Promo code engine supports percentage-off and fixed-amount discount codes, expiry dates, redemption limits, and single-use codes generated in bulk for affiliate or launch campaigns. Affiliate tracking uses UTM parameter ingestion at landing page entry with server-side session storage, tying each conversion to its originating traffic source. Conversion attribution reports show which channels, campaigns, and affiliates are generating paid enrolments, not just traffic. Course completion webhooks fire to Zapier, Make (formerly Integromat), or custom endpoints when a learner completes a course, enabling post-completion automations -- CRM record updates, certificate dispatch emails, cohort community invitations, or upsell sequence triggers. Course bundles group multiple courses at a single price point, with individual course access unlocked automatically on bundle purchase. Revenue reporting per course and per instructor shows gross revenue, refunds, net collected, and instructor payout owed. Refund handling is managed through the admin panel without requiring manual Stripe dashboard access.

Instructor dashboard shows enrolment numbers, module completion rates, assessment performance, quiz score distributions, video engagement drop-off points, and revenue analytics in one place -- giving course creators the data to identify which lessons are losing learners and which assessments are too easy or too hard. Multi-instructor support with configurable revenue sharing splits handles marketplace models, co-authored courses, and affiliate instructor arrangements, with payout calculation automated against recorded sales.

Multilingual content delivery with locale-based routing serves course content, UI labels, and notification emails in the learner's language. Content localisation workflows let instructors upload translated video files, subtitle tracks, and resource documents per locale without rebuilding the course structure. Locale routing selects the correct content variant automatically from the learner's browser locale or explicit language selection. Discussion thread management lets instructors respond to learner questions without leaving the platform, with thread notifications delivering via email or in-platform alert. Student Q&A moderation tools allow pinning the most useful answers, marking questions as resolved, and filtering by unanswered threads so instructors address the highest-value questions first. Bulk announcement and email tools let instructors reach their full enrolled cohort or a segment of it without requiring a separate email marketing tool.

Automated certificate generation fires on course completion with no manual admin work. Custom certificate design carries your branding, course name, completion date, instructor signature, and a unique verification code that links to a public verification page. For professional certifications that need to be independently verifiable by employers, universities, or licensing bodies, blockchain-anchored credentials use the Blockcerts open standard to issue a cryptographically signed JSON-LD credential anchored to a public blockchain (Ethereum or Bitcoin Blockchain). The issuer, recipient, award, and issue date are permanently and tamper-evidently recorded. Anyone with the credential file can verify it independently without contacting the issuing platform.

Shareable LinkedIn credential links use the LinkedIn Add to Profile deep-link format so learners can add their completion to the Licenses and Certifications section of their LinkedIn profile with two taps, extending your brand reach to every learner's professional network. Credential expiry and renewal workflows handle certifications with time-limited validity -- the platform sends renewal reminders before expiry and re-issues a new credential when the renewal course or assessment is completed. Bulk certificate generation for cohort completions issues credentials to all qualifying learners at the cohort close date without manual processing per learner. All credential issuance events are logged with timestamps and learner identifiers for audit purposes.

Course-specific discussion forums and Q&A threads per lesson give learners a place to ask questions and connect with peers without leaving the platform. Thread visibility can be scoped to the enrolled cohort or open to all platform learners, depending on your community model. For live cohort programmes where community happens off-platform, Slack workspace provisioning via the Slack API automatically adds learners to the cohort workspace and the correct channels on enrolment, and removes them on cohort close or course access expiry.

Peer assignment review workflows route completed assignments to two or three other enrolled learners for structured feedback based on a rubric defined by the instructor, with reviewer assignments managed automatically by the platform so the instructor does not coordinate manually. Live session scheduling for cohort courses integrates with Google Calendar and Outlook Calendar via their respective APIs -- session events with Zoom or Google Meet links are pushed to enrolled learners' calendars on creation, and reminder notifications fire 24 hours and 1 hour before each session. Re-engagement workflows trigger automated notifications to learners who have not accessed the platform in a defined number of days, with personalised messages referencing the specific lesson or module they left incomplete. The engagement data -- login frequency, content completion rate, community post count, and assignment submission rate -- feeds the instructor dashboard so instructors can identify at-risk learners and reach out before they drop off entirely.
