Gandharv Singh

I’m a Python / Django backend developer with 4+ years of experience designing scalable REST APIs, ETL pipelines, and data-driven automation systems. I focus on building production-ready backend architecture across SaaS, CRM, and fintech domains.

I’ve delivered measurable improvements in performance and reliability—optimizing PostgreSQL queries (including fixing N+1 issues), improving response times, and eliminating manual work through automation (including high-throughput extraction using Selenium and Python). I also design clean REST API data contracts with frontend teams to prevent integration mismatches.

To keep systems responsive and dependable, I decouple time-intensive jobs using Celery and implement async workflows where it matters. I’ve integrated third-party API-based ingestion pipelines and ensured transformed data lands in PostgreSQL and MongoDB reliably.

I enjoy collaborating cross-functionally with quant and UI/UX teams to translate requirements into working systems. I’m available immediately for full-time roles and want to keep shipping reliable, scalable backend services that handle real-world concurrency and edge cases.
