Learning Yogi

Helped designers with design requirements

What's possible in a given time frame?

How long any feature would take?

Would it be scalable?

Can we use these features globally?

Any technical design ideas that would help kids learn easily?

Quickly prototyped games

Created testable prototypes which can help designers in UET (User Experience Testing) with kids

Added improvements and new features in existing games

Built an Addressables system, and a Curriculum System to support more than 60 games

Procedurally generated a scrollable area to launch games based on kids learning progression

Build various platform systems:

Upsells - Client and Web support (JavaScript)

Referrals system - To invite new users and give free stories

Storybook mega pack - Contains 100s of stories

Unity package system to link multiple projects together

Built a speech-recognition game using Google speech to text APIs

Built an Art App with more than 50 activities

Built brushes, canvases, and techniques

Built the OLD Asset bundle system to dynamically deliver activities on demand

Created various Unity Editor tools to support designers

Developed protocols to optimize workflow

Took responsibility for the continuous release process

Built pipelines using Unity Cloud, allowing for easy deployment on Play/App store and Test Flight

Built pipelines for building Addressables

Helped backend team with development and release process

Helped in recruitment of new developers and QA engineers

Maintained technical documents for development processes

Designed and implemented content pipeline security for curriculum-driven game content, protecting proprietary educational assets from extraction and unauthorized redistribution

Built asset bundle encryption layer using AES-256 with per-asset keys, preventing direct dumping of game assets from device storage or network captures

Implemented integrity verification (HMAC signing) on asset bundles so tampered or injected content is detected and rejected at load time

Established secure content delivery pipeline with signed URLs, expiration policies, and token-based authentication for CDN-hosted assets

Applied obfuscation techniques (control flow flattening, string encryption, symbol stripping) to Unity assemblies to raise the bar against static analysis and ILSpy/dnSpy reverse engineering

Implemented application security measures safeguarding children's game data and progression, addressing COPPA and GDPR-K compliance requirements

Encrypted all personal identifiable information (PII) at rest using envelope encryption with per-user data encryption keys

Applied secure session management with token rotation, device fingerprinting, and anomaly detection to prevent account takeover and progression manipulation

Secured API communication with certificate pinning, request signing, and replay protection to prevent man-in-the-middle and data tampering

Implemented rate limiting and abuse detection on all user-facing endpoints to prevent progression farming and automated exploitation
