The bridge
Roadmaps and ROI reviews on Monday; Elasticsearch DSL and tRPC on Tuesday. I translate business intent into technical decisions — and technical trade-offs back into business language — without losing anything in between.

For future colleagues
Where I fit in a workplace
The shortest version: I sit in the gap between product and engineering — and I close it, in both directions.
High-stakes domains
I'm at my best where mistakes are expensive: a clinical EHR serving Swedish healthcare, pre-launch QA for banking apps, national-scale ERP programs, industrial B2B commerce. Compliance-first thinking is my default, not an afterthought.
Zero → production
I take products from blank repo to live customers. ELUX Travels — a multi-region travel booking platform — was designed, built and shipped solo: 460+ commits over 11 months, running in production today.
How I work
Requirements → design → build → measure, with artifacts at every step: models and specs stakeholders actually read, code that ships, dashboards that prove what happened. Evidence over claims, always.
Roles where I land:
Product Owner / PM — platforms, search & AI
AI Engineer — multi-agent systems
AI × Healthcare — clinical informatics
Technical Product Owner — search & data
Career arc
A decade, one direction
Each step added a layer: process rigor, clinical depth, platform scale — now the AI systems themselves.

Experience
Three rooms, one through-line
Consulting discipline, clinical product depth, platform-scale building.
Villvay Systems
Product Owner · Multi-tenant B2B search for Wurth companies
- Built the platform end to end: Airflow ETL, Elasticsearch on Elastic Cloud, Cloudflare Workers edge APIs, Next.js admin console — ~35k lines of TypeScript and Python in one Turborepo.
- Translated complex system flows into roadmaps and ROI-focused reviews for global stakeholders; led requirement elicitation, TO-BE architecture, prototypes and delivery timelines.
- Ran competitive and technology analysis across headless commerce, search and graph databases; owned quality metrics, Power BI dashboards and PIM data integrity.
- Earlier AI R&D: OpenAI and Hugging Face integrations for data-processing automation, plus POCs with v0, bolt.new and Claude Code for client feedback loops.
Cambio Software Engineering
Lead Business Analyst · COSMIC EHR, Swedish market
- Owned business analysis for the Overview module — consolidated patient information, care documentation, charting and operational insights — for a leading Nordic EHR.
- Worked with physicians, nurses, administrators, architects and developers across patient management, medication management, referrals, scheduling and clinical administration.
- Specified system logic, information structures and API designs to HL7, FHIR, openEHR, SNOMED CT and GDPR standards, API-first.
- Ran Design Sprints and human-centered design; produced UML models, Figma prototypes, acceptance criteria and managed backlog, UAT and release readiness.
KPMG
Trainee Business Analyst → Business Analyst → Associate Consultant
- ERP and business process re-engineering consulting across government, utilities, banking and finance, insurance, manufacturing, retail/FMCG and telecom.
- Ceylon Electricity Board ERP program: AS-IS study across 17 departments and ~150 processes; FRS workshops; TO-BE designs for procurement, inventory, asset and fuel modules.
- End-to-end ERP and core banking vendor evaluations — SAP, Oracle, Microsoft, Ebao, Misys, Temenos — from tenders and POC demos to recommendation reports.
- Data migration QA and pre-launch assurance for banking and insurance clients (SQL, Excel, IDEA) and for internet/mobile banking apps, a mobile wallet and a government e-Registrar.
Flagship work
Projects
Numbers below are taken straight from the codebases — nothing inflated, nothing vibes-based.
● Production
at Villvay
Villvay Search Platform
Multi-tenant B2B e-commerce search for Wurth industrial suppliers — ~35k lines of TypeScript and Python, 5 tenants isolated end to end.
- 16-layer relevance cascade from exact SKU to fuzzy, with tier suppression at result thresholds.
- Weighted Reciprocal Rank Fusion across 11 retrievers; ELSER sparse-vector semantic fallback computed at ingest, so query time pays zero inference.
- E-commerce linguistics: unit-of-measure synonyms, fraction/dimension normalization, per-account part numbers, barcode lookup.
- Zero-code tenant onboarding: config-only, 11 routes and 10 search collections per tenant.
- Airflow pipelines — one templated DAG generating per-tenant DAGs — syncing on 4-hour schedules with watermark incrementals.
- Config platform: 33 tRPC procedures, draft → preview → promote, one-click rollback.
● Production
eluxtravels.uk ↗
ELUX Travels
Multi-region travel booking platform — tours, hotels, flights, cruises — designed, built and shipped solo.
- ~46k lines of hand-written TypeScript, 23 routes, 22 CMS collections, 42 server actions, 460+ commits over an 11-month build.
- Next.js + Payload CMS 3 running as Cloudflare Workers via OpenNext, with edge ISR (R2 incremental cache, D1 tag cache, Durable Object queue).
- Block-based quote & itinerary builder producing branded quote documents with their own preview site; deposit and installment payment plans with proof-of-payment verification.
- TLD-driven multi-region: 5 currencies from one codebase, no client-side currency flashing; Google & Apple Sign-In, 5-role RBAC.
- Production data migrated from Neon Postgres to Cloudflare D1 via chunked replay scripts.
● Personal · 2026
AI App Generator
Describe an app in chat; a multi-agent system writes, executes and iterates on full Next.js apps inside cloud sandboxes with live previews.
- Mastra multi-agent pipeline: coding, title and response agents in a typed 4-step workflow with Zod-validated step contracts.
- E2B sandbox lifecycle management — sandboxes survive across turns; projects restored from Postgres into fresh sandboxes on expiry, on a custom Docker template.
- Long-term agent memory with semantic recall (FastEmbed embeddings in a LibSQL vector store) and AI tracing via Mastra observability.
- SaaS platform: tRPC end-to-end types, Drizzle on PostgreSQL, Better Auth, Polar metered billing, per-user rate limits.
- Streaming UX on Vercel AI SDK v5: streaming markdown, Shiki code views, live sandbox preview panel.
● Design study
AI Oncology Capstone
AI-assisted breast cancer early-detection and diagnostics module designed for the COSMIC EHR, in the Sri Lankan context.
- Full research → synthesis → ideation → POC design sprint, aligned to Cambio's roadmap and the EU Ethics Guidelines for Trustworthy AI.
- Three concepts evaluated through a weighted Harris Profile; selected a CNN clinician-assistant concept over a patient app and a risk model.
- Measurable AI requirements as design targets: 80%+ detection accuracy, 60% faster lab-investigation selection, ≤5 minutes screen time per consultation.
- Clinician-in-the-loop second opinions designed to discourage over-requisitioning invasive tests; anonymized scan-image repository proposed for AI development.
● Prototype
webcules-init & adjacent experiments
The earlier iteration of the AI app-generation platform — prototyped on the Vercel AI SDK with Supabase persistence and component-library-aware generation — later rebuilt into the AI App Generator on Mastra + E2B to add agent memory, sandboxing and orchestration. Alongside it: tru, a workflow-automation experiment on Cloudflare's edge stack, and webcules-ai-platform, an intent-to-execution agentic automation concept.
