What I'm looking for

I’m looking for a role where I can build secure, production-grade offline-first and real-time systems—especially cross-platform Electron or MERN products—while owning architecture decisions and delivering measurable performance and reliability gains.

I’m a Software Engineer focused on building high-performance offline-first systems with MERN and Electron.js. I design secure, efficient, production-grade architectures end-to-end, with a strong bias toward reliability in distributed environments.

In my current role, I’ve driven measurable improvements like reducing API payload size by 85% and improving synchronization across 20+ distributed instances. I engineered a 7-role RBAC system managing 30+ entities with zero permission bypass, and built scalable Redux architecture (38 slices) to support 15+ modules with optimized state updates.

Earlier work strengthened my offline-first foundation: I implemented PouchDB-based local data management for 10,000+ records, cut storage footprint by 40% using AES-256 encryption with zlib compression, and reduced sync time from 30s to 5s. I also built conflict detection with automatic document merging to prevent data loss, handling 500+ concurrent writes daily.

I also enjoy full-stack product engineering—scaling real-time user experiences with Socket.io, securing services with JWT and Redis session management, and improving performance using Elasticsearch and resilient patterns like circuit breakers. My projects reflect the same ethos: JSync Engine for offline-first realtime sync, with delta sync, compression, and CRDT conflict resolution.
