My professional journey and key experiences
Software Development Intern - Research & Development
Vivriti Capital Pvt. Ltd.
- Designed a full-stack Data Vault Management System utilizing Spring Boot, React.js, and REST APIs, establishing secure document storage and enterprise-level workflow management.
- Architected scalable backend modules for secure file upload, metadata processing, and lifecycle management, reducing data retrieval latency.
- Benchmarked and analyzed Ory Hydra alongside Keycloak to evaluate OAuth2/OpenID authentication capabilities, scalability, and robust token management.
- Implemented a customized IAM architecture integrating Ory Kratos and Keto to enforce centralized Role-Based Access Control (RBAC), secure session management, and API security.
- Constructed a high-performance C++ File Compression System supporting Text, PDF, MP4, and WebM formats, optimizing encoding workflows and significantly reducing storage overhead.
My Projects
File Compression Tool
Engineered a cross-platform CLI tool supporting 4+ file formats with 100% offline execution capability across Windows and Linux environments. Integrated 3 distinct compression engines (Zstd, FFmpeg, Ghostscript), successfully achieving a 60–80% reduction in overall file size. Formulated a 4-level compression hierarchy featuring custom bitrate and DPI tuning, delivering a 30–50% improvement in size-to-quality ratio control. Developed an extension-independent file signature detection system, boosting processing accuracy and reliability by approximately 40%.
ResumeIQ Hiring Assistant
Built a full-stack candidate screening web app using Next.js (SSG/SSR) and TypeScript, connected to NestJS REST APIs and a MySQL database to ingest and index resumes. Implemented a resume ingestion pipeline that processed resumes across 5+ sections, extracting and normalizing candidate data into a structured MySQL schema. Engineered an AI/LLM-assisted matching pipeline using RAG with a vector store (FAISS) to improve candidate-job matching precision by 15% on internal tests. Built a containerized 4-microservice ecosystem using Docker.
WordleDoodle
Real-time multiplayer word search game. Players join via shareable codes, scan a letter grid for hidden words in 8 directions, powered by a trie running in a Web Worker. A beautifully crafted, modern word-guessing game clone. It challenges players to guess a hidden word within a limited number of attempts, featuring smooth animations and an elegant user interface.
