Hi, I'm Tushar Jaiswal
4 years of professional experience designing and delivering scalable distributed systems, high-performance APIs, and event-driven microservices across production-grade backend infrastructure.
About
I'm a Backend-Focused Software Engineer with 4 years of professional experience, passionate about building scalable systems, high-performance APIs, and reliable backend architectures.
At Primathon (Gokwik), I work on KwikEngage — a multi-channel engagement platform serving 200+ merchants via WhatsApp, Instagram, Email, and more. I led the PostgreSQL → ClickHouse migration cutting analytics costs by ~40%, and optimised CDN delivery (CloudFront → Akamai) for high-throughput workloads.
Previously at TSAW Drones, I built drone precision-agriculture platforms — designing microservices for mission planning, collision avoidance, and real-time telemetry across 100+ missions.
I continuously invest in DSA, System Design, and Low-Level Design because great engineering starts with strong fundamentals.
Currently Exploring
Experience
- Collaborated on a scaled multi-channel engagement platform (WhatsApp, Instagram, Email, Facebook, RCS) serving 200+ merchants daily.
- Improved support efficiency by building Chat ID-based retrieval, streamlining agent workflows.
- Achieved ~95% billing accuracy by re-architecting billing, reporting, and alerting systems.
- Led PostgreSQL → ClickHouse migration for analytics, offloading 100% query traffic and cutting DB costs by ~40%.
- Optimised CDN delivery (CloudFront → Akamai) with caching strategies, reducing latency for high-throughput systems.
- Built MCP-based tools to reduce manual CSM effort by ~20% (targeting 90%).
- Built backend services for a drone-based precision agriculture platform — 100+ missions, 10+ concurrent flights.
- Designed microservices for mission planning, flight data processing, and analytics — reducing deployment overhead by ~25%.
- Developed drone path optimisation, collision avoidance, and real-time telemetry tracking, reducing mission risks by ~20%.
Software Developer
