Paisani Technology Services OPC Pvt. Ltd.

We modernize, stabilize and scale software that cannot fail. Our clients are product leaders in regulated and high-availability domains (Telecom, IIoT, Core Engineering, OEMs), and they hire us to remove risk while delivering measurable outcomes.

We specialize in:

Embedded Systems & IoT Edge Analytics — firmware, device drivers, on-device ETL and lightweight edge state (C / C++ / Rust).

Legacy System Stabilization & Modernization — L3 support, deep code archaeology, RDBMS tuning and phased migration roadmaps.

Data Engineering & Platform Performance — idempotent ETL, query-plan optimization, forensic-grade extraction, and high-throughput ingestion.

Scalable Systems & Platform Engineering — resilient, fault-tolerant architectures and repeatable infra-as-code patterns.

How we work: small senior teams (direct access to principal engineers), a disciplined PMO for delivery reliability, and long-term stewardship of the platforms we touch. We also contribute upstream — including maintenance work for Debian on IBM Z (s390x) — which reflects our commitment to sustainable, community-aligned engineering.
