What I'm looking for

I'm looking to build end-to-end, high-impact SaaS and real-time products, from user-facing experiences to scalable backend systems, infrastructure, and production deployments.

I've built Gmail-like webmail, Slack-style chat, Google Drive-like file collaboration, and a unified OAuth 2.0 SSO experience at Yukthi Systems. These products serve 100K+ active users and include real-time messaging, calls, video streaming, file versioning, billing, analytics, and administration.

I engineer Go microservices, automation, release pipelines, and production deployments across the platform. I also led the GPL-3.0 open-sourcing of core repositories, including high-throughput email archival and synchronization tools operating at million-email scale.

Previously at AtticBits Solutions, I built Workstation, a workflow and business management platform used by 500+ companies, alongside hiring, booking, inventory, and productivity products. I implemented WebSocket-based bulk resume parsing that processed 21,000+ resumes in a single run.

Through freelance and personal projects, I've delivered e-commerce, POS, mobile, ed-tech, and secure PDF-sharing products, including PdfWarden and Codemy. I work across React, Next.js, React Native, Node.js, Go, PostgreSQL, MongoDB, Redis, and AWS to take products from idea to deployment.
