Selected Work

Around five years building software across healthcare, fintech, eCommerce and enterprise SaaS, with recent work focused on applied AI. A selection of projects, grouped by type.

AI & Machine Learning

4 projects
Agentic AI

Agentic Assistant for PLM and CAD

M.Sc. thesis, University of Oulu.

An LLM agent that takes plain-language requests from an engineer and carries them out against SolidWorks and 3DEXPERIENCE data.

  • Tool-calling loop with a typed action schema, so each step maps to a real API call
  • Retrieval over engineering documents and part metadata
  • Confirmation step before any action that writes to model or PLM data

Signal Processing

EEG Connectivity Analysis Pipeline

Research project, Center for Applied Computing, University of Oulu

Processing pipeline for recordings from a four-channel EEG headset, built to run the same way across subjects.

  • Blink and saccade artifact removal tuned for low channel counts
  • Band-power extraction and connectivity metrics across electrode pairs
  • Batch runs with per-subject reports

Applied LLM

Product Catalog Enrichment

eCommerce platform, nopCommerce extension

Normalises supplier product data and drafts descriptions, with a review step before anything is published.

  • Attribute extraction and mapping into the store taxonomy
  • Description and meta text drafting with per-category rules
  • Background jobs so large catalogue runs do not block the admin

Retrieval

Document Intelligence Service

Enterprise SaaS, internal knowledge tooling

Semantic search across contracts, specifications and internal documents.

  • Ingestion with parsing, OCR, chunking and embedding
  • Vector search with metadata filters and keyword fallback
  • Results limited to documents the user already has access to

nopCommerce Plugin

Bulk Order Import

Food and bakery distribution, B2B

Replaced manual entry of emailed order spreadsheets with a validated upload.

  • CSV and Excel upload with row-level validation and a preview step
  • SKU and customer code mapping to the buyer’s own part numbers
  • Background processing with a per-row error report

Platform

Multi-Store nopCommerce Build-Out

Retail and display manufacturing

Several storefronts on one install, each with its own catalogue, currency and tax rules.

  • Shared theme and checkout with per-store overrides
  • Shipping and tax provider plugins for multiple markets
  • Customisations kept in plugins to protect the upgrade path

Headless

Headless Storefront

React front-end on a .NET commerce API

New storefront in front of an existing commerce backend, so the shop could be rebuilt without touching order processing.

  • Statically generated product and category pages with revalidation
  • Cart and checkout against the existing commerce API
  • Faceted search with filter state held in the URL

Voice Calling App

React Native for Android, Node.js backend

In-app calling between users and out to ordinary phone numbers, including when the app is closed.

  • Twilio Voice SDK for client-to-client and outbound PSTN calls
  • FCM push to wake the app for incoming calls
  • Express backend issuing access tokens and serving TwiML routing

Healthcare

Pharmacy and e-Prescription Platform

Patient and pharmacy portals

Connects patients, prescriptions and pharmacies through a single fulfilment workflow.

  • Prescription upload with pharmacist review states
  • Fulfilment queue, order tracking and delivery status
  • Role-based access with an audit trail on clinical records

Enterprise SaaS

Admin and Reporting Portal

Internal operations tooling

Back-office application covering accounts, entitlements, usage and month-end reporting.

  • Server-side paging, filtering and export on large tables
  • Scheduled report generation with email delivery
  • Shared React component library across screens

Automation

Content Automation Workflows

n8n publishing pipeline

Fetches article content from a source site and reduces it to clean text for downstream use.

  • HTTP fetch and HTML parsing to isolate the article body
  • Normalisation and de-duplication before storage
  • Retry and error branches for failed pages

System Integrations

3 projects
Fintech

QuickBooks Accounting Integration

Two-way sync with a product database

Keeps customers, invoices and payments in step between the product database and QuickBooks.

  • OAuth 2.0 flow with token refresh and per-tenant credentials
  • Idempotency keys on sync operations to prevent double posting
  • Webhook handling plus a scheduled reconciliation pass
C#/.NETQuickBooks APIOAuth 2.0SQL Server
ERP

ERP to Storefront Sync

Distribution, back office to web

Moves products, prices and stock levels from the ERP to the storefront.

  • Delta sync on change timestamps rather than full catalogue pushes
  • Queue-based transport so ERP downtime delays the sync instead of breaking it
  • Configurable field mapping and unit conversion per feed
.NETRabbitMQREST / SOAPSQL Server
Payments

Payment and Shipping Gateways

Several storefronts and markets

Payment and carrier integrations behind a common provider interface.

  • Hosted and embedded payment flows with 3-D Secure and refunds
  • Webhook verification and replay protection on status callbacks
  • Live carrier rates, label generation and tracking updates

Microservices & Cloud

3 projects
Architecture

Monolith to Microservices

.NET on Azure

Extracted capabilities from a large .NET application one at a time while it stayed in production.

  • Service boundaries drawn around business capabilities, each with its own data
  • API gateway in front, monolith still serving anything not yet moved
  • Asynchronous messaging between services
.NET CoreAzure Service BusAPI GatewayAzure
Containers

Kubernetes Deployment

Docker, AKS and EKS

Standardised how services are built, configured and deployed across environments.

  • Multi-stage Docker builds with configuration supplied through secrets
  • Liveness and readiness probes, resource limits and autoscaling
  • CI/CD pipelines running build, test and deploy on merge

Performance

Distributed Caching Layer

.NET Core services with Redis

Caching applied across services, with invalidation driven by domain events rather than fixed expiry times.

  • Redis distributed cache with an in-memory first tier for hot keys
  • Output and response caching on read-heavy endpoints
  • Tag-based invalidation and hit/miss metrics
