Tellme began as an AI guide for museums, live at three national museums and winner of the Innovate UK Agentic AI Pioneers Prize 2025 (Creative Industries). The company is now pivoting to Troopa (troopa.ai): an AI teammate that takes part in your meetings as they happen, so the decisions and next steps get done in the call rather than after it.

Co-founder & Chief Technology OfficerJun 2026 - Present · 5 mos · Belfast · Hybrid3 points

Made a co-founder of Tellme AI in June 2026, leading the technology through the company's pivot from museum guides into meeting productivity.

  • Building Troopa (troopa.ai), an AI teammate for meetings on Microsoft Teams, Zoom and Google Meet: rather than a note taker that reports afterwards, it takes part in the conversation and helps move it towards a decision while everyone is still in the room.
  • In the call, anyone can say “Hi Troopa” and ask, or type a question only they can see, and the answer appears on screen from what has been said, earlier meetings, shared documents or the web. It builds boards such as timelines and estimation poker as people talk, and when the call ends it writes the notes: the outcome in one line, the topics, and the next steps with who took each on.
  • A desktop app for Mac, Windows and Ubuntu that listens in from the person's own computer, with nothing added to Teams, Zoom or Meet. It keeps the words but never the audio, stores no voiceprints, and keeps each organisation's meetings in the UK, the EU or the US.
Chief Technology OfficerDec 2025 - Jun 2026 · 7 mos · Hybrid10 points
  • Building a centralized, scalable platform that brings together AI capabilities, application layers, and infrastructure to significantly reduce the time, cost, and effort required to deploy the solution at new museums and attractions.
  • Designing automation-first deployment pipelines and standardized workflows to enable rapid, repeatable rollouts of the point-and-discover experience across multiple cultural venues.
  • Actively developing a centralized Aggregation & Observability Platform to monitor all deployed museums from a single portal, unifying visitor engagement, behavioural insights, feedback, and system health.
  • Designed and built the self-service museum kiosk (Android 14, Kotlin + Jetpack Compose) that sells on-site access to the digital guide end to end: attract loop, card tap, and a printed receipt carrying the redeem QR, opening a second sales channel that runs without staff involvement.
  • Integrated unattended payment hardware and peripherals directly, driving the myPOS Sigma Unattended SDK alongside an ESC/POS receipt printer, QR referral scanning, and NFC admin access, behind a terminal abstraction so payment providers can be swapped without touching the flow.
  • Built the fleet management layer for kiosks in the field, covering heartbeat and command polling, remote reboot/refresh/reprint, silent over-the-air updates with staged rollout via device-owner PackageInstaller, a watchdog, and durable on-device logging for crash triage.
  • Made the kiosk resilient and locale-aware for real venue conditions: offline ticketing fallback when the network drops, on-device evaluation of museum opening hours so it closes itself outside them, per-kiosk configuration overrides, and simultaneous bilingual screens (e.g. Welsh alongside English).
  • Kept visitor presence detection privacy-preserving by processing the camera feed entirely on-device and transmitting only abstract presence events, never imagery.
  • Working hands-on with museum visitors on-site, observing real usage of the mobile point-and-discover web app to identify friction, bottlenecks, and usability gaps and drive true product–market fit.
  • Defining the platform and product strategy with a strong focus on user-centric design, operational scalability, and continuous learning, ensuring the experience improves with every new deployment.
Founding EngineerJun 2025 - Dec 2025 · 7 mos · United Kingdom · Remote8 points

InnovateUK-funded tech startup building a visitor-centric point-and-discover experience for museums and attractions.

  • Fine-tuned and integrated the provided computer vision components (embeddings, ONNX inference, model outputs) into the mobile web application, optimising performance and reducing battery drain on low-end devices by over 50%.
  • Designed and built the full mobile-first, edge-optimised web application for a point-and-discover experience used in museums and cultural spaces, including the frontend (Next.js) and backend (FastAPI) along with all supporting infrastructure.
  • Developed the complete backend architecture using Python (FastAPI) and MongoDB, covering APIs, data models, content pipelines, and embedding management workflows.
  • Built the comprehensive Admin & Content Management Portal, enabling curators and internal teams to manage collections, metadata, assets, geometries, and discovery logic through a streamlined interface.
  • Architected and implemented the full CI/CD and DevOps ecosystem using GitHub Actions, with automated builds, deployments, testing pipelines, and environment management.
  • Delivered a reliable and scalable cloud infrastructure on AWS, including Amplify, CloudFront, S3, EC2, CloudWatch, and AWS Backup, ensuring performance, monitoring, and resiliency across the entire product.
  • Designed and built a rule-based Retrieval-Augmented Generation (RAG) Prompt Engine: a dynamic prompt construction system using definitions, templates, rules, and composable components, powering the conversational AI layer of the application.
  • Delivered all core components (frontend, backend, admin portal, DevOps pipelines, AWS infrastructure, integrations, and performance optimisations) within a rapid 4 to 6 month timeline to achieve a production-ready MVP.

Bootstrapped from a university boarding room into Sri Lanka's go-to provider of insurtech, and scaled it to a team of 60+ through to a successful exit. I stayed hands-on the whole way: the systems below are ones I architected and built, not ones I signed off.

Founder & Chief Executive Officer2017 - 2025 · Colombo, Sri Lanka6 points

Bootstrapped EchonLabs into the go-to provider of future-proof insurtech in Sri Lanka, recognised for driving digital transformation across the insurance sector.

  • Grew the company from a university boarding room to a team of 60+, through to a successful acquisition and exit. Drove 50% growth in insurance-tech adoption and built a low-code framework that cut development costs by roughly 30%.
  • Legify.ai, an AI legal-contract platform. Led the end-to-end architecture, and engineered a jurisdiction-based Retrieval-Augmented Generation engine that tailors legal content to the regional laws and compliance frameworks that actually apply. The hard part was not retrieval; it was making jurisdiction a first-class dimension of it. Multi-tenant SaaS, role-based access, audit logging.
  • InsurEL, the most complex architecture of my career. A modular ecosystem of 6+ integrated web and mobile systems covering the full spectrum of insurer operations: microservices-based and API-first, supporting serverless and serverful deployment from one core, with dynamic workflow builders, AI risk engines, fraud monitoring and adaptive actuarial modules.
  • PropEL, a performance and KPI system for sales teams that replaced Excel-driven workflows. Built around a formula builder querying Oracle, MongoDB, APIs and master files, so users compose complex KPI rules without writing code, with real-time analytics and flexible commission structures.
  • LOLC Life Assurance OneClick: architected and launched what is now the #1 insurance self-care app in Sri Lanka, recognised among the best in the South Asian region. Policies, payments, claims and status across iOS, Android and web, on AWS serverless microservices.
  • Janashakthi Life, a digital insurance platform adopted by 15+ financial institutions across 300+ branches, including rural locations. Architected for low-bandwidth environments so it stayed usable over 2G and 3G, which is the constraint that decided most of the design.
