About

Backend Software Engineer with 1+ year of experience building production-grade Go microservices at scale. Currently at Antier Solutions, I've led end-to-end delivery of a blockchain abstraction product and designed core infrastructure across a cloud marketplace platform — owning services in auth, billing, marketplace, and team management. I specialize in event-driven architectures (Redpanda/Kafka), API security (RBAC, JWT, Envoy), and distributed systems design — including mechanisms like fund locking, session isolation, and cross-chain intent orchestration. I care about correctness under failure, clean architecture, and systems that hold up in production. Outside the happy path, I've diagnosed and fixed Kafka consumer group starvation bugs, resolved PostgreSQL bottlenecks under load, and secured smart contract interactions with ERC-712 signing and AES encryption. Open to connecting with engineers, teams, and opportunities in backend infrastructure, distributed systems, and Web3.

Work experience

Associate Software Engineer at Antier Solutions, Apr 2024 - Present · 2 yrs 2 mos, Mohali, Building and maintaining production-grade Go microservices across two products — owning 4 services end-to-end in a blockchain abstraction platform and 2 core services in NXT, a cloud infrastructure marketplace. • Led the full lifecycle of a blockchain abstraction product: architecture design, smart contract integration (ERC-712, AES encryption), and production release. • Built a centralized RBAC authorization gateway in Go, integrated with Envoy Proxy for path-based access control, JWT authentication, and IP/geo-based restrictions. • Designed event-driven inter-service communication using Redpanda (Kafka-compatible), processing ~400K–500K messages/day with zero failures and environment-scoped consumer group isolation. • Engineered dual-role session isolation with separate cookie domains for concurrent user and admin sessions, backed by a Redis sliding-window token refresh system. • Diagnosed and resolved a critical Kafka consumer group starvation bug caused by shared group IDs across dev and prod environments. • Identified and resolved performance bottlenecks across services, Kafka pipelines, and PostgreSQL layers — improving throughput and reducing latency under load.
