About

The person
behind the code.

I'm a Quantitative Technology Specialist with 20 years of experience across hedge funds and investment banking — most recently as VP and Technology Lead at WorldQuant Singapore, where I spent 12 years building the infrastructure that powers systematic alpha generation at scale.

My work lives at the boundary between quantitative research and engineering. I don't just build tools — I architect systems that let researchers move faster, catch errors before they cost money, and push signals into production with confidence. The problems that interest me most are the ones where getting it wrong has a real cost.

Outside of institutional finance, I'm a self-directed trader. I built RDX from scratch — for personal NSE equity trading. It keeps me honest. There's no better teacher than a position that moves against you.

I hold the CMT Level I certification — and it genuinely changed the way I see markets. Technical analysis gave me a language for price itself: structure, momentum, the geometry of sentiment playing out in real time. Combined with a programming background, it opened up a different kind of edge — the ability to define rules precisely, backtest rigorously, and remove as much emotional noise as possible.

I have deep respect for fundamental analysis. It provides conviction that technical analysis alone rarely can — understanding why something should be valued differently gives you the confidence to hold through noise. But fundamentals move slowly. By the time they're reflected in consensus, price has often already moved. Technical analysis tells you when the market is ready to agree with you. The combination — knowing what to own and when the market is ready to reward it — is where the real edge lives.

I've spent years as a student of the Vedas and Vedantic philosophy — not as an academic exercise, but as a genuine practice. The Upanishads have shaped how I approach problem-solving: stripping a system to first principles, questioning assumptions at every layer. Neti neti — not this, not that — is as useful in system architecture as it is in philosophy.

Music has always been a parallel thread. I've been a student of Carnatic classical music for years — drawn to its mathematical rigour, its deep grammar of ragas and talas, and the discipline of improvising within structure. It shares more with quantitative thinking than most people expect.

For most of my adult life I trained seriously in bodybuilding. These days I've moved toward yoga — a slower practice, but no less demanding. The shift from building outward to building inward has been instructive in ways I didn't anticipate.

Vice President, Technology Lead
WorldQuant Singapore
  • Alpha Generation Reliability — Engineered production pipelines ensuring 99.99% alpha signal generation before market open, implementing automated failure detection, root-cause analysis, and permanent fixes across distributed compute clusters — directly protecting P&L from signal gaps and missed trading opportunities.
  • Global Team Leadership — Built and led a globally distributed team of 15 engineers (Singapore, Vietnam, Mexico, Budapest) providing 24×7 coverage across research infrastructure, with direct and indirect oversight across all delivery functions.
  • Platform Ownership at Scale — Technology Lead for 24 global research initiatives (AlgoLabs), spanning alpha discovery workflows, tooling, automation, and infrastructure across equities, futures, forex, ETFs, and crypto.
  • $5B+ P&L Impact — Platforms built and governed under this leadership directly supported over $5 billion in actual P&L across the last two years, underscoring the business-critical nature of system reliability, delivery precision, and operational excellence.
  • Monitoring & Stabilization — Designed and deployed a real-time monitoring system (Python + Grafana + alerting stack) that captured alpha generation failures, logged root causes, and reduced mean time to resolution (MTTR) by >60%.
  • Core Research Portal & AlphaDB — Architected the central alpha submission portal with technical validation (syntax, runtime checks) and policy enforcement. Established and governed AlphaDB — the golden source for all alpha-related information underpinning strategy creation.
  • Enterprise Data Lake — Directed the design and governance of a multi-petabyte distributed data lake central to alpha research and strategy creation. Engineered a complex permissioning layer controlling researcher access based on visibility and entitlements, alongside a data replication framework maintaining two governed copies of production data. Built user-facing data discovery tools and APIs allowing researchers to browse, explore, and programmatically access datasets.
  • Pipeline Engineering & Scaling — Scaled alpha submission and generation pipelines from 75K to 2M signals by redesigning the legacy workflow architecture. Implemented automated onboarding modules, distributed testing pipelines, and performance optimisations across compute farms, ensuring fault tolerance and high throughput.
  • Model Test Framework — Core maintainer of the Alpha Model Test Framework — a mission-critical component of the alpha factory pipeline. Owned the full operational layer including runbooks, SLA management, and escalation procedures. Led codebase migration from Perl to Python, introducing modular architecture, CI/CD pipelines, and automated regression testing.
  • AI & NLP Pipeline — Built AI pipeline models applying NLP techniques by designing job processes that collected and transformed live newsfeeds into sentiment datasets, utilising Python and distributed data processing frameworks.
  • Alpha Thematic Group — Engineered the Alpha Thematic Group platform — a cross-team system enabling dynamic ingestion of new alphas, retirement of obsolete signals, and generation of next-day trading signals, accelerating thematic research and portfolio construction.
  • Infrastructure Migration — Directed organisation-wide scheduler migration from Condor to Slurm, redesigning job orchestration, resource allocation, and monitoring for thousands of daily research jobs across global clusters.
  • Portfolio Manager Onboarding — Defined and implemented an optimised onboarding workflow for new portfolio managers, covering the full lifecycle from dataset access and alpha submission through to monitoring alpha status and verifying P&L performance.
  • Alpha Upgrades — Directed large-scale alpha upgrade projects involving thousands of signals, ensuring smooth migration to new simulators and dataset changes with minimal disruption to live strategies.
  • Policy & Governance — Collaborated with research teams to shape alpha submission and upgrade policies, influencing research direction and compliance across the organisation.
  • Executive Analytics — Built a Grafana-based analytics dashboard aggregating multi-source data streams with drill-down metrics on alpha performance, data quality, and monetisation — actively used by C-suite leaders.
  • Agile Delivery — Managed technical delivery via JIRA-driven sprints, backlog prioritisation, and close collaboration with research leads to align technical execution with alpha research goals.

Assistant Vice President
Barclays Capital Ltd
  • Migrated legacy client and counterparty applications from ASP.NET to C#, redesigning architecture across seven modules — achieving 80% improvement in system performance leveraging C# and .NET 3.5.
  • Built an automated MQ message validation framework in Perl, reducing regression testing from 24 man-days to 30 minutes, directly improving release efficiency and lowering production incident risk.
  • Developed automated environment synchronisation utility in Perl, reducing sync time by 95% and supporting 30+ deployments monthly with consistent accuracy.
  • Designed a release automation framework with Perforce, reducing release cycle times by 95% and deployment errors by 99% across DEV, UAT, and PROD environments.
  • Led testing and deployment for Autosys product upgrade across four critical banking applications, mitigating operational risks and enhancing defect discovery rates.
