Commercial specialist with 3+ years of end-to-end ownership of the cost & commercial lifecycle for M&E and electrical construction projects across Singapore. From first estimate to final account.
I don't just manage cost on paper — I understand the work, the systems, the contractors, and where the real money moves.
I'm Sathiyaseelan Ramasamy — known to most as Sathish — a Commercial Manager specialising in Electrical and M&E construction projects across Singapore, with a parallel track in AI-assisted development.
Over the past 3+ years, I've independently managed the full commercial lifecycle on projects up to SGD 3.55 Million — handling cost estimation, quantity take-off, subcontractor procurement, variation claims and contract administration with full client-facing accountability. Not as support. Not in an assistant capacity. As the person responsible.
"I understand how M&E contractors build their rates, where they price risk, and how to protect a client's commercial position — because I've managed it from the inside."
My background spans an MBA from the University of Sunderland (UK) and a First Class Engineering degree from Anna University — giving me both the strategic commercial thinking and the technical grounding in electrical systems, LPS and earthing works that most commercial professionals lack.
Beyond construction, I build web tools, dashboards and automation workflows using AI-assisted development — leveraging Claude and modern AI platforms to deliver clean, functional digital products fast. This dual capability allows me to bridge the gap between commercial project delivery and digital innovation.
I've contributed to over SGD 10 Million in project value across electrical, LPS and infrastructure works. I've managed Singapore's entire tendering operation remotely from Dubai — proving I deliver results regardless of circumstance. Now seeking to bring this expertise into cost consultancy, critical infrastructure or data centre environments.

A career built through consistent growth, real accountability and results across Singapore and international markets.
Every competency here has been applied with real accountability — on live projects and real products.
Need M&E commercial expertise without a full-time hire? I work with contractors, developers and consultancies across Singapore on a project or retainer basis.
Business strategy and engineering fundamentals — the combination that sets me apart from both sides of the commercial table.
Whether you're looking to hire a Commercial Manager, need MEP cost support for a project, or want to explore a freelance engagement — I'd like to hear from you.
