Work Experience

Software Development Engineer

Biz2X

Sep 2025 - Present
  • Redesigned a Redis-based caching layer for high-traffic APIs, reducing average response times by 40–60%, lowering database load, and improving system performance under concurrent traffic.
  • Developed secure and scalable distributed backend services by optimizing large-scale data retrieval for 100k+ records, implementing refresh token-based session validation, and orchestrator-level rate limiting handling multiple microservices traffic.

Software Development Engineer

MiM-Essay

Feb 2025 - Aug 2025
  • Designed scalable backend services for a B2B analytics platform used by 200+ businesses, enabling AI-driven sales automation workflows and reducing manual follow-up effort by 60% through automated calling and intelligent messaging systems.
  • Migrated WhatsApp messaging infrastructure from WATI to an in-house API and integrated LangChain + Python AI services, improving template delivery by 35%, lowering third-party costs, and automating lead response workflows.

Projects

Cache-DB - (Redis-Inspired In-Memory Database)

View Project
GoRedis
  • Built a Redis-compatible database in Go with RESP protocol, pipelining, string/list/hash types (20+ commands), and MULTI/EXEC/WATCH transactions with optimistic concurrency control.
  • Compared two concurrency models — single-threaded epoll (raw syscalls) vs goroutine-per-connection — goroutines hit 80K ops/secon single commands; epoll reached 277K ops/secon pipelined workloads.
  • Implemented active+lazy key expiration, crash-safe AOF persistence with atomic compaction, and a custom benchmark tool with p50/p99 latency tracking across 50 concurrent clients.

Real-Time Analytics System

View Project
ReactSocket.IOKafkaRedisMongoDBDocker ComposeNginxk6
  • Architected a full-stack real-time analytics platform with a React dashboard displaying live metrics via Socket.IO, powered by Kafka event streaming, Redis counters (24h TTL), and MongoDB daily aggregates, containerized with Docker Compose and reverse-proxied through Nginx.
  • Implemented idempotent Kafka producers with bounded-backoff recovery, a two-tier storage layer for sub-millisecond reads and persistent roll-ups, and validated the pipeline at 398 req/s with 20ms median end-to-end latency under 200 concurrent users using k6.
