I build firewalls from scratch — the hard kind, with Linux network namespaces, nftables packet pipelines, and TLS interception. Currently the sole backend engineer at WiJungle, where I've been architecting a Next-Gen Firewall platform from zero. Not just features — the entire stack: multi-tenant control plane, data plane, inspect engine, HA clustering, distributed routing, and real-time telemetry. What I've built at WiJungle: → Multi-tenant architecture where each tenant runs in a fully isolated Linux network namespace with independent RBAC → HA cluster with NATS JetStream + Keepalived/VRRP — <3s failover, 99.9%+ availability → Distributed routing control plane with BGP/OSPF/RIP via FRR — 200+ dynamic routes, <100ms convergence → nftables packet pipeline with AST-based rule compiler — firewall rules, NAT, QoS, IDPS, app-aware filtering → L7 inspect engine (in progress): TProxy, TLS MITM, DNS sinkhole, Suricata signatures → Real-time telemetry pipeline with Redis clustering + ManticoreSearch — <500ms queries across 5TB+ daily traffic → Authored 20+ architecture design documents. Mentored 4 interns. → This work enabled Rs. 20+ crore in government contract bids under Make in India. Before WiJungle — 5 years at Trellix/FireEye (promoted Associate → SDE in 2 years): → Helped migrate SOAR platform from single-tenant on-prem to multi-tenant cloud SaaS — 1000+ customers → Built high-performance log parsing microservices for cloud SIEM (NXLog, UDP/TCP ingestion) → Built 15+ security connectors (Splunk, CrowdStrike, Palo Alto) — worked directly with enterprise customers → Contributed to multi-million dollar deals: Bancolombia, MTR Corporation → Drove on-prem to cloud migration with Docker, Kubernetes, Terraform Core: Go, Linux Networking (namespaces, nftables, TProxy, conntrack, FRR), NATS, Redis, AWS, Kubernetes Interests: Distributed systems, network security, HA design, system architecture IIIT Allahabad '20 · 500+ LeetCode · JEE Main Top 1% · Samsung SWC Qualifier

Joined as Associate Software Engineer, promoted to Software Development Engineer within 2 years. Worked on the SOAR (Security Orchestration, Automation, and Response) platform backend. • Contributed to re-architecture of SOAR platform backend from single-tenant on-prem to multi-tenant cloud SaaS, helping scale to 1000+ customers processing 5M+ alerts/day • Built high-performance log parsing microservices for cloud SIEM platform, processing events ingested via NXLog integration over UDP/TCP with scalable, fault-tolerant pipeline • Worked directly with enterprise customers on plugin integration and playbook creation; built 15+ security connectors (Splunk, CrowdStrike, Palo Alto, etc.) • Contributed to securing Bancolombia (one of Latin America's largest banks) — helped deliver solutions that drove their transition from IBM to Trellix's TuAR product, contributing to a multi-million dollar contract • Worked directly with MTR Corporation to resolve critical issues across multiple security integrations, contributing to the successful renewal of a multi-million dollar contract • Drove deployment strategy migration from on-prem to cloud using Docker, Kubernetes, Terraform; improved deploy frequency from weekly to daily, reduced failures by 75% • Designed event processing pipeline using AWS Lambda, Step Functions, S3, API Gateway with <200ms p99 latency across multi-region deployment • Integrated observability tooling (Prometheus, Grafana, CloudWatch) for production debugging, memory leak tracking, and performance profiling across microservices Tech: Python, Go, AWS (Lambda, Step Functions, EC2, S3, API Gateway, CloudWatch), Docker, Kubernetes, Terraform, PostgreSQL, Redis, Kafka, Prometheus, Grafana, GitHub Actions
