I’m a software engineer with a strong problem-solving mindset and a drive to tackle tough challenges. I enjoy building reliable systems and using cutting-edge tech to ship impact-driven solutions, especially where data pipelines and automation matter.

As an Application Engineer at CommerceIQ, I built scalable crawlers and APIs handling millions of requests, and I architected robust ETL pipelines to load large volumes of unstructured e-commerce data into centralized data warehouses for downstream analytics. I designed internal dashboard applications using the MERN stack (MongoDB, Express.js, React, Node.js) to monitor pipeline health and crawler performance, and I deployed containerized scraping systems with monitoring, autoscaling, and fault-tolerant design.

I also work deeply on reverse engineering and stability: I used Frida and HTTP Toolkit workflows to extract undocumented APIs, and I addressed rate limits, IP bans, and bot detection with adaptive throttling, proxy rotation, and fingerprint evasion. Earlier, as a Junior Software Developer at Tri-Bee Software Solutions, I developed Angular UI pages and built Node.js APIs with Mongoose, supported testing with JavaScript Selenium scripts, and used Jira to collaborate effectively with the team.
