Work Experience

Pathao
June 2025 — Present
Gulshan 2, Dhaka
Current
Software Engineer
  • Pathao Loop — Engineered a robust, cron-driven campaign orchestration platform that powers engagement for 2.7M users daily. Loop enables teams to design, schedule, and execute complex multi-channel campaigns across push, SMS, email, and in-app messaging from a single interface, saving 10,000+ man-hours annually while accelerating rollout and measurement across Pathao services.
  • Pathao Itihas — Built a unified feature-store platform for Pathao Ride, Food, and Parcel that ingests historical data from BigQuery and PostgreSQL, synchronizes to real-time tables, and uses Redis-backed caching. Exposed feature delivery through REST and GraphQL APIs with async task-queue execution, alerting, and metric discovery for reliable model-ready data access.
  • Pathao Popular Pickup — Developed a pickup recommendation service that suggests the most reliable and commonly used pickup points based on demand and location patterns, reducing pickup confusion and improving trip conversion quality for riders.
  • Developer Automation Platform (n8n) — Set up and maintained n8n as a shared internal automation platform for engineering teams. Built an event consumer service that processes system events and routes them to both real-time streams and n8n workflows, enabling cross-team automation for alerts, operations, and internal engineering tasks.
  • ESB Webhook — Designed and scaled a centralized webhook processing system that transforms incoming payloads into standardized ESB events with schema validation, idempotency controls, retry mechanisms, and end-to-end monitoring to improve reliability and simplify third-party integrations.
  • Litmus — Contributed to Pathao's in-house A/B testing platform by implementing stable hash-based user bucketing, configurable experiment rules, and rollout controls, allowing product teams to run safer experiments and make decisions from trustworthy experiment outcomes.

Junior Backend Engineer
  • TL Rating and Review — Engineered a comprehensive post-trip rating and review system that allows both shippers and owners to evaluate each other, strengthening platform trust, transparency, and accountability.
  • TL Challan Management System — Developed an end-to-end challan workflow to manage document uploads, status tracking, and verification flows for dispatcher and challan operations teams.
  • TL Image Server — Spearheaded development of a performant image service on Google Cloud Storage for uploads, retrievals, and deletions, optimized with Redis caching for faster repeated access.
  • TL Notification Service — Collaborated on a robust push and in-app notification architecture serving shipper and owner applications alongside internal operational dashboards.
  • TL Message Server — Built a RabbitMQ-based message broker to support maintainable and reliable real-time messaging delivery across core user flows.
  • TL Marketing Panel — Architected a dynamic campaign management panel in Golang with GCS-based media handling for banners and documents, supporting operational speed and flexibility.
  • Truck Lagbe Login Project — Migrated legacy login services from Node.js to Beego while preserving backward compatibility and ensuring seamless integration with the existing ecosystem.
  • Slow Query Optimization — Performed deep analysis and optimization of 15+ complex SQL queries, improving endpoint performance by 25–40% on high-traffic APIs.
