The Founder

Rufina Lee, Founder & CEO, Ollumia

Rufina Lee is the Founder and CEO of Ollumia, and the methodology author responsible for the diagnostic framework used across all Ollumia personal colour analysis services. She holds final responsibility for methodological design, diagnostic scope, observation conditions, analyst calibration, and validation boundaries. All diagnostic outcomes delivered by Ollumia operate within frameworks she defined and governs.

Professional Background
Management Consulting

Rufina Lee began her career in management consulting at Accenture, working on the CIMB–Southern Bank–Bumiputra-Commerce Bank merger integration, one of the largest banking mergers in Southeast Asia at the time. The work focused on operating model integration, process alignment, and project management across a complex multi-entity transition.

This was an early exposure to how systems fail quietly during transition, how misalignment compounds across teams, and how decisions made on paper behave differently when executed under real delivery constraints.

Financial Markets — Standard Chartered Bank

She later spent close to a decade in Financial Markets at Standard Chartered Bank, advising corporate clients on foreign exchange and interest rate risk across Singapore, Vietnam, and Malaysia. During this period, Rufina established Ho Chi Minh City's first dealing room for the bank, operating as the sole on-the-ground lead during setup and early operations.

These environments demanded precision, discipline, and a clear separation between signal and noise. Decisions had to hold under scrutiny, audit, and repetition. The cost of error was immediate and real.

Reliability — GrabFood Indonesia

Rufina Lee's first role at Grab was Head of Reliability for GrabFood Indonesia, at a point when the platform was a new entrant in one of the most competitive food delivery markets in the region. Reliability had to be designed without mature technology, requiring close on-the-ground observation, creative non-technical workarounds, and empathy-led problem solving.

Systems were built to function under non-uniform conditions, absorbing local variation instead of assuming ideal or centralised environments.

Platform Scale — 175 Cities

Building on this reliability foundation, Rufina Lee later led the expansion of GrabFood operations across 175 cities in Indonesia. Consistency had to be engineered through structure and sequencing, not imposed through uniform rules. What worked in one city could not simply be copied into another without distortion.

Southeast Asia's First Grab Merchant Centre

In parallel, Rufina created Southeast Asia's first Grab Merchant Centre, a physical, operations-led hub designed to onboard merchants, diagnose operational failure, and standardise execution at scale. The centre integrated people, process, and tooling to allow problems to be surfaced, examined, and corrected directly in context, rather than inferred from dashboards alone.

Singapore — Platform Propagation

In Singapore, Rufina Lee led changes to GrabFood's merchant operating model that materially improved platform reliability. The merchant operating landscape she established later became the foundation for merchant onboarding and execution across Grab platforms, including GrabPay, GrabMart, GrabExpress, and Grab for Business.

→ GrabFood ranked number one among food delivery platforms in Singapore by consumer brand health, based on external brand health surveys conducted during her tenure.
→ During the COVID-19 lockdown period, her work onboarding and supporting merchants in Singapore was recognised with the Grab CEO Award.
From Platform Systems to Diagnostic Methodology

Across management consulting, financial markets, and platform-scale operations, Rufina Lee has repeatedly worked in environments where reliability could not be assumed and intuition was insufficient. These were settings shaped by variation, scrutiny, and real human behaviour, where systems failed quietly before they failed visibly, and where trust was earned only when outcomes held under pressure.

Ollumia applies the same discipline to personal colour analysis. The methodology was developed by carefully defining what can be directly observed, what must be controlled to make observation meaningful, and what cannot be inferred without introducing distortion. Rather than relying on intuition, trend, or category, it operates within clear observational and methodological bounds: a diagnostic framework for observing colour response on human skin under controlled conditions, with explicit limits on scope and claims.
