• ⚙️ Backend engineer with 6 months of production experience at a London-registered B2B SaaS startup (SvaraAI)
• 🔧 Built systems from scratch — 14K req/sec HTTP server in C and 17.04K req/sec distributed job queue in Go
• 🧠 Work across systems programming, distributed systems, AI pipelines, and full-stack SaaS
• 🐧 Linux enthusiast who reads kernel docs for fun

→ Redis-backed job queue built from scratch in Go

• Priority scheduling via lexicographic score encoding on Sorted Sets
• Atomic Lua-scripted dequeue — eliminates race conditions under concurrent load
• Retry engine with exponential backoff + jitter, Dead Letter Queue, job replay
• Prometheus metrics: queue depth, job duration histograms, worker utilization
• Multiple queue support using round robin polling for job processing.
• 76,800 req/sec across 3 queues zero failed requests (in memory interface)
• 17,040 req/sec across 3 queues zero failed requests (redis based interface)

Full-Stack Developer Intern @ SvaraAI (Oct 2025 – Mar 2026) London-registered B2B SaaS startup — Remote

• Developed microservice for domain based email architecture. Created Inbound SMTP using node.js and Outbound using Azure email services. Created a schema based routing for inbound and outbound email.
• Spotted unauthorized user on companies VM, got to know it was because of open ports. Removed the user using sudo privelages, also removed the cron job he created. After that secured the system by blocking unused ports and increased firewall strictness on used ports.
• Completed auth migration from per user based auth to organization based auth with RBAC, zero downtime DB migrations.
• Created a CI/CD pipeline from scratch that used github webhooks and ran bash scripts on server for deployment.
• Created a custom text editor with font support and style support like lists that converted text to html to be shared in email for proper rendering.
• Wrote NGINX setup scripts for different services with domain certificate registration.
