I’m a Backend & Integration Engineer specializing in high-throughput data pipelines and bi-directional CRM/ERP synchronization. I focus on shipping integrations that stay correct under load—high throughput, zero data loss, and predictable behavior across real-world failures.

In my current role, I’m currently shipping 9 concurrent production pipelines processing up to 1–4 lakh records per cycle using Node.js, TypeScript, and OAuth 2.0. I reduced pipeline failure rates by 40% through intelligent retry logic, structured observability, and idempotent upsert design.

I design architectures that make duplicates impossible and recoveries automatic—engineering ETL Pipelines with strict duplicate-matching, idempotent upserts, parallel execution, and intelligent batching. I also build secure data handling, including converting complex file attachments to Base64 to preserve binary fidelity across platforms.

I’m especially proud of outcomes like automating HubSpot → NetSuite financial synchronization, eliminating ~8–10 hours/week of manual reconciliation work. I’ve also cut cross-platform CRM lag from hours to under 5 minutes, optimized API call volume by ~60% with delta polling, and reduced lead-routing errors by ~90% while improving processing time from minutes to seconds.
