I worked as a full-stack

I worked as a full-stack software engineer on Kalakar.io, an AI captioning and video-editing SaaS platform. I implemented its subscription billing system and ElevenLabs-powered audio processing, and contributed to the frontend and backend product experience.

The platform supports multilingual transcription, editable captions, media uploads, usage-based plans, cloud storage, team accounts, and several professional export formats. I have build the following features on this app: -Automatic captions for more than 20 South Asian and international languages - English and other mixed-language transcription - Roman and native script selection - Editable word-level captions - Timeline-based caption editing - Custom caption templates, fonts, colors, and animations - AI audio cleaning and background-noise removal - Video and audio uploads - Batch uploading - Translation into English - Horizontal and vertical video formats - Rendering up to 4K at 60 FPS - SRT and VTT subtitle exports - Alpha-channel caption rendering - Green-screen and blue-screen rendering - Transcript exports in DOCX, TXT, and Markdown - Premiere Pro and DaVinci Resolve support - Subscription plans and recurring payments - Transcription, translation, and storage limits - Add-on credit purchases - Team workspaces and per-member billing - Recent projects and storage-usage dashboards
