About

Backend developer focused on building reliable and scalable systems. I work mainly on backend systems, databases, and architecture, and I enjoy understanding how systems behave under real-world load and failure conditions. I have experience building multi-tenant systems from scratch, designing data pipelines for large datasets, and working closely with databases at both the application and internal levels. I care deeply about tradeoffs around performance, consistency, and maintainability. Alongside building systems, I write technical articles that break down real-world system design problems and database internals. My writing covers topics like PostgreSQL MVCC, storage engine tradeoffs, real-time communication systems, and distributed analytics. Currently, I am exploring system design and distributed systems more deeply, using writing and hands-on work to reason about architecture decisions and scaling challenges. Always open to conversations around backend engineering, system design, and learning from production systems.

Technical Writer : Backend Systems & Databases

Sep 2025 – Present · 8 mos

Write long-form technical articles breaking down backend systems, database internals, and distributed system design.
Cover real-world topics such as PostgreSQL MVCC and vacuuming, storage engine tradeoffs (B-Trees vs LSM trees), analytical systems with Trino, outage analysis, and networking fundamentals.
Focus on explaining how large-scale systems behave under load, where failures occur, and how architectural decisions impact reliability, performance, and scalability.
Use writing as a tool to reason about production systems, tradeoffs, and engineering design decisions.

Software Developer

Feb 2025 – Present · 1 yr 3 mos · Noida, Uttar Pradesh, India · On-site

Built a multi-tenant backend system from scratch, owning database design, core architecture, and service boundaries.
Designed and implemented data pipelines to ingest and process large in-network files (~500GB), orchestrated using Airflow.
Worked on a lakehouse-style architecture using Iceberg and Trino to store and query optimized Parquet data efficiently.
Focused on building reliable, scalable systems with clear tradeoffs around performance, storage, and cost.
