Portrait of Rahul Raj N, software engineer and CTO, Thiruvananthapuram

I turn complex ideas into software that ships.

I lead engineering at Suffix E Solutions and still write the code: full-stack systems, LLM-based products and the architecture underneath them.

01About

About Rahul Raj N

I bridge the gap between business strategy and shipped code.

Five years of building software products across several stacks. I went from Software Engineer to Project Head to CTO, and I still review code, design systems and ship features myself.

A

Business thinking

Turning requirements into architecture, and keeping design, backend and mobile teams moving in one direction.

B

Engineering execution

System design, code review, LLM integration and APIs. I still build, taking products end to end from the first commit to production.

How I work

From problem to production.

Not just writing the code: understanding the problem, designing the system, building it, and taking it live.
