Engineer

About

I’m Keshav, a software engineer at jpteam / C1X Inc. I build systems and investigate the engineering problems underneath them — the silent failure behind an HTTP 200, the keyspace mismatch behind an idle queue, the read path that should never have been computing anything.

Professional focus

Production backends in a multi-product organisation spanning FinTech compliance, Document AI, enterprise conversational AI and high-concurrency dynamic media platforms. Most of that work is a GST compliance and Document AI platform, where I was a primary contributor across the core domain service and the document extraction worker: ledgers with correct tax math, IMS reconciliation with the GST portal, GSTR-1 and GSTR-3B filing, a document-AI extraction pipeline, durable real-time notifications, and tenant isolation.

Systems interests

The parts of a system that decide whether it is correct under load and under failure: concurrency control (Redis locks around redemption and OTP verification), async pipelines and their contracts (BullMQ keyspaces, domain events), read models, and the security boundary between tenants.

AI infrastructure

The engineering around models rather than the models themselves: classification guards in front of expensive OCR, retrieval that is decided rather than automatic (BARA), explanation built into detection (ACFS), and review automation that is structurally unable to change the code it reviews (Antigravity).
