About
One team from the idea to the delivered product.
ZAIRA TECH builds custom software, designs the electronics and PCBs behind it, supplies the hardware it runs on — and delivers all of it as one project. Technology projects rarely fail on any single layer. They fail in the gaps between vendors.
Our story
Why we work this way
The company is led by Santhosh P, who came to software from the plant floor rather than the other way round. A Diploma in Mechatronics, two years commissioning PLCs, SCADA, drives, and HMIs for a Siemens systems house, a B.E. in Electronics & Communication Engineering, and a year at Craftsman Automation — then full time across software, IoT and embedded work together.
That order matters. The platforms we build are used by the kind of operation he spent years working inside, which is why the work spans web and mobile application development on one side, and embedded firmware, Linux and Android on single-board computers, PLC and automation programming, and circuit board design on the other.
That combination is deliberate. When a system misbehaves, the question is whether the sensor, the board, the firmware, the network, or the software is at fault. A team that built all of them can answer that in an afternoon. A chain of suppliers can spend a month establishing whose problem it is.
Today the work covers custom software and mobile apps, IoT, PLC and automation systems, electronics and PCB design, Android touch displays and kiosks, and IT hardware supply — carried from the first conversation through design, build, installation, and support under AMC.
Alongside project work we deliver our own product line — industrial PLCs, monitoring and telemetry systems, and ready-built platforms that began as client projects and were productised once the same requirement came up often enough.
We are based in Coimbatore and work with clients across manufacturing, industrial automation, infrastructure and utilities, energy, fleet operations, trade, and healthcare — including government monitoring deployments.

Background
Sixteen years from the shop floor to the software.
Automation first, electronics next, software last — and all three still running together. That order is the opposite of how most software companies are built, and the reason this one can answer for the whole system.
2010 – 2013
Diploma in Mechatronics
PSG Polytechnic College, Coimbatore. Mechanical, electrical, and control engineering together — the discipline this company still works across.
2 years
Service Engineer — Siemens systems house
Commissioning and servicing PLCs, SCADA, variable-frequency drives, and HMIs on live plant equipment. Faults diagnosed on running machines, not on a bench.
Graduated
B.E. Electronics & Communication Engineering
Sri Ramakrishna Engineering College, Coimbatore. Electronics, embedded systems, and communication — the layer beneath the automation work.
1 year
Craftsman Automation
Precision manufacturing at scale, and a close view of what production systems are actually asked to do on the shop floor.
Since then
Software, IoT and embedded work
Web platforms and mobile apps on one side; embedded firmware, Linux and Android on single-board computers, PLC and automation on the other — built for the same plants and sites the earlier years were spent inside.
July 2026
Founded ZAIRA TECH
Registered as a sole proprietorship in Coimbatore, to deliver the software and the hardware as one scope instead of two.
Principles
How we approach the work.
One team across every layer
Software, firmware, and hardware problems get solved on whichever side is cheaper to change. That is only possible when the same team owns all of them — otherwise every boundary becomes a negotiation.
Delivered, not just designed
We stay with the project through production, installation, and commissioning, and support what we deliver under AMC. A design that never reaches the site has not delivered anything.
Built for the site, not the demo
Field conditions decide the design. Power that fluctuates, networks that drop, environments that are hot and dusty. A system that only works on a bench has not been engineered yet.
Specified for the job
Boards, displays, and computers are chosen against the work they will actually do and how long they stay in service — not the lowest price that passes on day one.
Handover you can maintain
Documented schematics, readable code, and infrastructure your own team can run. We would rather you did not need us for routine changes.
Honest scoping
If a project is outside what we do well, we say so at the first conversation rather than the third invoice.
Work with us
We take on a small number of projects at a time so each gets senior engineering attention throughout. Start with a free conversation about the problem — you speak to the engineer who would build it.
