Senior full stack engineer, five years deep in identity, ingestion and delivery pipelines — 6M+ device packets a day, 82% of database load removed, and the dashboards on top of it all.
I'm Samyak — a senior full stack engineer who gravitates to the systems other people avoid: tenant isolation, permission models, event pipelines that must never drop a message, and the deploy story that makes all of it boring to run.
I work end to end — Java and Spring Boot on the backend, React and Angular on the front, Azure and Kubernetes underneath — and I measure my work in latency, load and lag, not tickets closed. What sets me apart is that I ship: architecture decisions come with commits, dashboards and runbooks behind them.
Auth was hitting PostgreSQL on every request across every tenant, throttling the whole platform.
Designed a multi-tenant IAM service with hybrid RBAC, tenant isolation, audit logging and Redis permission caching — plus 25+ Spring Boot APIs for JWT validation, permission evaluation and session management.
Telemetry ingestion lagged behind devices and double-processed events with no dead-letter story.
Rebuilt ingestion on Azure Event Hub with partition-aware async consumers, batch + checkpoint tuning, DLQ and idempotent processing. Now also delivers 200K+ notifications daily with zero duplicate ingestion.
Logistics operators ran sales, payroll and commission on spreadsheets and disconnected tools.
Shipped a lead-to-conversion ERP covering sales, HR, payroll, commission and slab modules with fine-grained RBAC and Razorpay / Axis / ICICI gateways secured by hybrid encryption — plus a high-traffic VSL funnel on Cloudflare Workers.
Roles, contracts or an interesting architecture problem — I reply to every message that isn't a template.
