With deep expertise in Kotlin, Java, Go, Android SDK, Dagger/Hilt, Retrofit, Node.js, Spring Boot, MongoDB, Docker, Kubernetes, and GitHub Actions, I excel in crafting high-performance software solutions. As a Full Stack Engineer at 0Chain, I specialize in Android development and backend engineering, delivering innovative solutions for decentralized cloud storage. I have developed Android apps Bolt and Vult, ensuring seamless integration with blockchain-based storage systems and robust system performance. Passionate about open source, I’ve contributed to Oppia, GNOME, and Google Summer of Code, designing CI/CD pipelines, enhancing build processes, and mentoring developers. Beyond coding, I actively lead development sessions, organize hackathons, and drive innovation in software engineering at my college.
Launched a new AWS region (Australia) for the testing platform, now serving 360K requests/hour in production. ◦ Cut dashboard load time from 3–4 min →3 s via indexed queries, unblocking a stalled enterprise deal. ◦ Built the access-control system from the ground up — RBAC with multi-team support across∼14 enforcement points. ◦ Root-caused a stale role mapping that hid 756 builds from customer dashboards; shipped the data and access-check fix. ◦ Drove a 208×query speedup (9.6 s →46 ms) on a 524M-row table via a zero-downtime schema migration across 4 regions. ◦ Averted an outage via zero-downtime primary-key migrations on 3 tables of 1B+ rows (∼1TB) growing 2.9M rows/day. ◦ Shipped input validation on high-traffic APIs (100M+ calls), adding multi-language support across web and SDK clients. ◦ Built test-run aggregation combining a run and its re-runs into accurate consolidated duration, status, and ordering. ◦ Cut database CPU from 96% to stable by offloading heavy aggregate queries to a columnar store (ClickHouse). ◦ Remediated SQL injection across 50+ APIs and rolled out CI security scanning covering∼98% of traffic.
• Refactored GoSDK and collaborated with cross-platform teams to enhance functionality. • Developed UAT tests for enterprise storage to ensure robustness and reliability. • Implemented CI/CD pipelines for mobile teams to streamline development processes.
• Implemented MVVM architecture to enhance code maintainability and scalability. • Utilized Dagger/Hilt for efficient dependency injection in third party libraries. • Developed high-quality XML layouts from Figma wireframes and integrated Realm database for data storage.
◦ Shipped 2 production Android apps, Bolt and Vult, driving 20% adoption growth and $2M+ in blockchain transactions. ◦ Built a UAT automation suite for blockchain storage, cutting bugs by 90% and release cycles from 2 weeks to 3 days. ◦ Optimized S3-compatible storage handling 500M+ files and 40TB+ across 50+ nodes at sub-100ms latency, 99.9% uptime. ◦ Automated dynamic Sharder/Miner management and view-change protocols, boosting developer productivity by 90%. ◦ Enhanced multi-wallet concurrency via unified Go SDK, supporting 10K+ concurrent transactions and 300% load-test gains.
• Mentored students and junior members in tech, conducted Android/Web/Open Source sessions, and organized hackathons. • Facilitated learning and growth opportunities for tech enthusiasts at Axios, IIIT Lucknow.
