Why Work With Me

Expertise You
Can Trust.

Most consultants go deep on one domain. I bridge four — and that breadth is the advantage your project needs.

Internationally Trained
MSc in Renewable Energy Engineering from Brunel University London — one of the UK's top engineering institutions. Every recommendation is evidence-based, not sales-driven.
Real Engineering Background
Not just advisory — hands-on R&D engineering experience at EEB Engineering Design & Consultancy, spanning product development and energy systems.
End-to-End Delivery
I scope, brief, manage, and quality-check. You get a single point of accountability — no chasing multiple vendors.
"The best engineers don't just solve problems — they ask better questions first."
— Rakesh Servai

About

Rakesh
Servai.

Renewable Energy Engineer & Multi-Domain Consultant

I'm a Tamil Nadu-based engineer and consultant with over seven years of experience spanning renewable energy, product development, digital systems, and sustainable living. My work sits at the intersection of technical rigour and real-world practicality — I don't just advise, I engineer solutions.

Currently working as R&D Engineer and Consultant at EEB Engineering Design & Consultancy Services — leading active projects in BESS market analysis, ESS project economics, and new product development. International academic rigour combined with hands-on industry R&D means advice that is both technically sound and practically deliverable.

My approach is straightforward: understand the problem deeply, brief the right expertise, oversee execution, and deliver outcomes that hold up under scrutiny. No fluff, no scope creep, no surprises.

Core Values

How I Work.

01
Discipline
Every project gets a written scope, a milestone structure, and a clear outcome definition. Ambiguity is the enemy of good engineering.
02
Honesty
If your idea isn't feasible or your budget doesn't match your expectations, I'll tell you before you spend a rupee — not after.
03
Accountability
You have one point of contact. I own the outcome — not just my slice of it. Specialists are briefed, managed, and QC'd by me.
