Kalapi Infotech designs and builds firmware for connected embedded products. Architecture and BSP work, RTOS and bare metal development, secure boot and OTA infrastructure, and the certification evidence that goes with them. The work spans RF, aerospace, SATCOM, smart metering and IoT.
Two kinds of people reach this page. Pick whichever sounds like you, then use the form at the bottom.
You have a firmware project
Whether you are planning a new product or your existing firmware has outgrown the architecture it started with, we would be glad to talk it through.
The conversation moves faster if your message covers four things.
- The target. MCU or SoC family, and whether the hardware is already fixed.
- Where it is now. Greenfield, a working prototype, or production firmware that needs restructuring.
- The constraint that worries you most. Timing, memory, power, security, certification, or your team’s bandwidth.
- Your timeline, even roughly.
You do not need a specification to write in. A paragraph and an approximate date is enough to work out whether there is a fit.
You are here from the interview guides
The guides are free and stay that way. If you found an answer that is wrong, incomplete, or that a real interviewer would push back on, say so. Corrections get made.
- Embedded Firmware DSA Interview Guide, 248 questions across seven parts
- Firmware Architecture Interview Questions, 100 answers for senior and staff roles
- Embedded C interview questions

If you are preparing for a specific round and cannot find the topic anywhere in the guides, tell us what is missing. Gaps that come up more than once get written.
