About

I’m a results-driven Python Developer with expertise in building secure, scalable, and high-performance applications. Skilled in Django, FastAPI, Flask, and Django REST Framework, with expertise in RESTful API development, I excel at crafting backend systems that power impactful digital solutions. My technical toolkit includes PostgreSQL, React, Redis, and microservices architecture, combined with cloud and DevOps expertise in AWS, Docker, Nginx, CI/CD pipelines, and Git/GitHub with GitHub Actions. I am experienced in Linux/Unix environments, utilizing pytest and unit testing to ensure code quality. Security is a top priority—I implement JWT, OAuth, and endpoint protection to safeguard data and user trust. I thrive in collaborative environments, working closely with cross-functional teams to transform ideas into production-ready systems. What I’m Looking For I’m seeking opportunities to design and deliver innovative, high-impact software solutions in a growth-focused, tech-driven environment—while continuously learning and contributing to the success of the team and the organization.

Design and develop data ingestion pipelines for Excel files, structured folder inputs, and marketplace feeds, ensuring reliable end-to-end processing.
Normalize, validate, and transform marketplace-specific catalog formats into unified internal schemas to support consistent reporting and automation.
Work extensively with Flipkart, Amazon, Shopsy, and Noon-style catalogs, handling real-world data inconsistencies, schema variations, and platform-specific edge cases.
Write and optimize MySQL queries to debug missing or incorrect seller data, Audit channel-wise and seller-level reports, and investigate ingestion and reporting mismatches in production
Develop web scraping and automation workflows to:
Programmatically download product thumbnails from external sources and marketplace pages, Validate image integrity, formats, and mapping against catalog data, Upload and sync corrected thumbnails back into internal systems and pipelines, Build automation scripts for bulk operations, including: Thumbnail correction, replacement, and validation at scale, FTP-based file verification, ingestion, and cleanup, Batch execution of catalog and listing fixes driven by Excel inputs
Diagnose and resolve production issues involving:
Data integrity failures and missing records, Validation and type-mismatch bugs, Silent ingestion gaps caused by control-flow and edge-case handling errors
Actively support live systems by performing deep root-cause analysis instead of applying temporary workarounds.
