Software Engineer | 3 Years Experience | Node.js, React, RabbitMQ, PostgreSQL, Cassandra DB

I'm a software engineer with nearly 3 years of experience as founding engineer building scalable distributed systems. I build scalable distributed systems and real-time communication platforms that operate at production scale. Scaled B2B startup from 0 -> 500 customers.

Shipped AI workflows, RAG pipelines, and agentic orchestration, blocking 100% of 10 attack vectors via custom guardrails.

Top 5 things I have built.

• 01 Distributed job scheduler with RabbitMQ processing 100K+ daily tasks.
• 02 Real-time telephony microservice architecture processing 500K+ daily call logs.
• 03 AI learning platform with multi-model orchestration, observability and dual-stage RAG.
• 04 Browser-based AI video editor generating animations from natural language.
• 05 Custom virtualized DOM softphone UI rendering 1M+ call logs efficiently.

High-Throughput Telephony Architecture

• Architected multi-instance real-time telephony services using SIP.js and FreeSWITCH across 9 microservices.
• Implemented concurrency-safe routing using Cassandra Lightweight Transactions (LWTs).

Data Migrations

• Executed live, dual-write migrations of 20+ Cassandra tables with over 15 million rows from DataStax to self-hosted infrastructure.
• Built fault-tolerant Node.js automation that successfully bypassed mid-run version incompatibilities without crashing.

Distributed Schedulers

• Built a shard-based distributed job scheduler processing over 10,000 daily tasks.
• Enforced epoch fencing for zero split-brain incidents.
• Tuned gc_grace_seconds to eliminate tombstone bloat, dropping Cassandra read timeouts to zero.

Real-Time Notification Engines

• Engineered a RabbitMQ and WebSocket event pipeline processing over 500,000 daily events.
• Sustained 500 messages per second with sub-50ms latency for live call state webhooks.

Data Reliability & Optimization

• Redesigned logging pipelines to append-only logic, achieving 100% call state accuracy and eliminating complex backend reconciliation.
• Cut final status latency by 80%, dropping it from 5 seconds to 1 second.

Infrastructure & CI/CD

• Orchestrated a Docker Swarm environment for 19 microservices.
• Built tag-driven automated CI pipelines that enabled 8 or more zero-downtime weekly production releases.
