• At Cloudfeather Games, a gaming tech startup, I joined as a Founding Engineer and led the frontend engineering efforts, helping build and scale products at the intersection of gaming and web technologies.
• My primary focus was on the development of Bountyverse, a proprietary JavaScript SDK designed to integrate seamlessly with HTML5 games. Bountyverse enables games to plug into real-money rewards, achievements, leaderboards, and real-time player actions — turning casual games into monetizable, competitive experiences.
• 🔹 Key Contributions:
• 1. Built Bountyverse SDK from scratch using JavaScript, enabling seamless integration into any third-party HTML5 game with minimal overhead.
• 2. Designed it to capture in-game events, scoring logic, player actions, and outcomes for analytics, rewards, and leaderboard tracking.
• 3. Developed a full-featured admin dashboard using ReactJS + NextJS + TypeScript, allowing internal teams to manage games, users, scoring rules, rewards, and performance metrics in real time.
• 4. Integrated 15+ HTML5 games into the Bountyverse ecosystem. This included:
• (i)Reverse-engineering and adapting game core logic
• (ii)Customizing scoring mechanisms for fairness and anti-cheat
• (iii)Hooking into gameplay events to enable action tracking and analytics
• 4. Ensured all integrations were high-performance, cross-platform compatible, and responsive across devices and game engines.
• 🔹 Team Leadership:
• 1. Led the frontend engineering team, setting up code architecture, best practices, and CI/CD pipelines.
• 2. Collaborated closely with game developers, backend engineers, and product managers to ensure end-to-end delivery and high user engagement.

• As a Lead Engineer, I focused on platform-level security features for Samsung's Android devices, working on Sensitive Data Protection (SDP) and Dual Data-at-Rest (Dual DAR) encryption, both critical components of Samsung Knox.
• In the SDP project, I helped secure sensitive user and enterprise data (biometrics, credentials, enterprise keys) through hardware-backed encryption and policy-enforced access control. I worked on isolating data using TEE (Trusted Execution Environment), Keymaster, and Knox Keystore. I contributed to encryption key lifecycle management, ensuring keys were accessible only after secure authentication and revoked on events like screen lock or session timeout. I also integrated fscrypt-based encryption policies into Secure Folder and Knox Workspace environments.
• In the Dual DAR project, I worked on building a dual-layer encryption system that uses both device-level (FBE) and container-level (Knox) encryption. This ensured that sensitive data remained protected even if one layer was compromised. My work involved implementing key separation, managing secure boot flows, and integrating MDM policy controls for enterprise key provisioning and revocation.
• I also led a small team, conducted design/code reviews, collaborated across Knox and platform security teams, and contributed to the secure data path for critical use cases such as enterprise mobility and regulated industries.
• Tech Stack: Android, C/C++, SELinux, fscrypt, Knox, Keymaster, TEE, Git, ADB

• At Samsung Research Institute, Noida, I was part of the Mobile Security and Enterprise Mobility teams, where I worked on several core platform features related to security, data encryption, and enterprise partitioning for Samsung Android devices.
• 🔐 SELinux Permission Automation Tool
• In my early phase, I contributed to Samsung's internal SELinux (Security-Enhanced Linux) infrastructure. SELinux is essential for enforcing mandatory access controls (MAC) in Android.
• 1. Developed an automation tool that analyzed access logs and denial events to auto-generate permission rules for SELinux.
• 2. The tool helped reduce the manual effort of system engineers in auditing and configuring policy exceptions during the development of new features or system modules.
• 3. Integrated with Samsung’s custom Android build pipeline for real-time feedback and iterative policy refinement.
• 4. Improved both development speed and security compliance by reducing human error in SELinux configurations.
• (Note: Since SELinux policy creation can be tedious and error-prone, automating rule generation based on actual denial logs can significantly speed up development while maintaining strict security boundaries.)
• 🗂️ Enterprise Partition Manager (EPM)
• Later, I joined the Enterprise Partition Manager team, where I worked on managing secure partitions and data isolation for enterprise use-cases — primarily focused on Secure Folder and Samsung Knox functionality.
• 1. Contributed to the creation and lifecycle management of secure partitions, used in Knox Secure Folder and work profiles.
• 2. Worked on logic for isolating personal and enterprise data using containerization and hardware-backed encryption keys.
• 3. Helped ensure data-at-rest protection and seamless integration with enterprise policies (e.g., remote wipe, data separation, encrypted boot).
• 4. Ensured compatibility with Android’s Device Policy Manager (DPM) and enterprise MDM (Mobile Device Management) frameworks.

• At Samsung Research Institute Noida, I worked on a project focused on enterprise data security within the Samsung mobile ecosystem — particularly addressing the challenge of safely using third-party (BYOD) Samsung devices in enterprise environments.
• 🔹 Project Goal:
• To enable users to securely store and access enterprise data on personal Samsung devices, without compromising organizational security policies.
• 🔹 Key Contribution:
• I developed a proof-of-concept that allowed enterprise data to be securely encrypted and stored on a third-party Samsung mobile device. The solution leveraged Samsung Knox, Samsung's enterprise-grade security framework, to isolate and protect sensitive information.
• 🔹 Security & Integration:
• 1. Ensured data was encrypted both at rest and in transit
• 2. Integrated with Knox APIs to enforce device-level security policies, enabling features like containerization and remote data wipe
• 3. Focused on data integrity and compliance, critical for regulated enterprise environments

• I co-founded Infistart Solutions, an EdTech startup focused on improving access to quality education through intelligent and user-friendly technology solutions.
• At Infistart, I primarily led the frontend development efforts — designing and building intuitive, responsive user interfaces that made complex educational tools easy to use for both students and educators. I worked closely on creating platforms that integrated AI/ML-powered features while maintaining a strong focus on user experience (UX) and accessibility.
• 🔹 Key Contributions:
• 1. Designed and developed clean, functional frontend interfaces using modern web technologies
• 2. Worked closely with the product and backend teams to bring AI-driven features to life
• 3. Ensured a seamless user journey for educational institutions and learners
• 4. Helped define product vision and align it with real-world educational needs

• During my internship at IDRBT Hyderabad, I had the opportunity to work on a pioneering prototype aimed at digitizing traditional banking instruments — Digital Cheques and Demand Drafts — as part of a broader initiative to modernize core banking technologies.
• My role focused on both the development and security aspects of the platform:
• 🔹 Project Overview:
• I built an end-to-end system that allowed banks or individuals to issue digital cheques and demand drafts, and enabled users to upload and process them online to complete transactions — reducing the dependency on physical documents and enhancing convenience.
• 🔹 Security Innovation:
• To address the risk of document forgery, I implemented embedded watermarking on the digital instruments. This tamper-evident watermark acted as a security layer to prevent fraud. I used MATLAB to develop the watermarking algorithm and seamlessly integrated it into the document generation flow.
• 🔹 Tech Stack:
• Frontend: HTML, CSS, JavaScript
• Backend: PHP
• Image Processing & Watermarking: MATLAB
