Software Engineer · Backend & AI Engineering
Six years of building things people actually use. .NET Core and Vue.js in production: multi-tenant ERPs, a Stripe-powered webshop, and a cross-platform desktop app that somehow picked up 89+ GitHub stars. I care as much about how a system is designed as whether it ships. I hold an MSc from the IT University of Copenhagen . My thesis benchmarked JIT compilation trade-offs across V8, JavaScriptCore, and SpiderMonkey. These days that means pointing the same systems instincts at AI engineering.
Experience & Education
Boneappetitedk (eCommerce) :
- Built a Copenhagen-based dog-food subscription webshop from scratch on .NET Core, Vue.js, and PostgreSQL — no Shopify or WooCommerce.
- Built a dog-profile quiz that generates a personalized meal plan before checkout, with Stripe-powered recurring billing.
- Owned deployment end-to-end: self-hosted the backend via Webmin (chosen over Azure to cut hosting cost), frontend process-managed with PM2.
Data Story (SaaS) :
- Built an LLM-powered analytics pipeline (Next.js, Supabase) that classifies insights from Excel/CSV data as trend, correlation, anomaly, or distribution.
- Designed a bring-your-own-key architecture, letting each user configure their own API key, model, and system prompt.
- Generated role-aware reports: executive summaries for managers, technical detail for data engineers, plain-language steps for frontline workers.
Copenhagen dog-food subscription webshop — built solo on .NET Core, Vue.js, and Stripe.
LLM-powered analytics dashboard, built for a client. Not publicly hosted.
- Built an advanced inventory management system (Lekhastra), inspired by SAP, for 30+ department stores across Nepal, increasing work efficiency via bulk operations.
- Maintained multi-tenant backend infrastructure and a POS desktop application used daily across multiple store branches.
- Decoupled legacy .NET Framework applications by building RESTful APIs and consuming them in Frontend Application making it easier to maintain and scale.
- Optimised PostgreSQL database performance using advanced indexing and query techniques to improve overall store productivity.
- Developed ERP systems (Crystal ERP) and POS applications for hotels and cafés using .NET Core, delivering high-performance and user-friendly interfaces.
- Worked on the initial design phase in Figma to shape the end-user experience, cutting development iteration cost.
- Managed private Linux server deployments, maintaining 99.9% uptime for client-facing systems.
Academic background
Completed an MSc thesis, “Benchmarking JIT Compilation Trade-offs Across JavaScript Engines,” supervised by Professor Peter Sestoft — analysing runtime optimisation across V8, JavaScriptCore, and SpiderMonkey. The coursework includes algorithm design, parallel programming, Big Data, Advanced Software Engineering, Machine Learning and Computer System Performance.
Foundation in software engineering, data structures, algorithms, and full-stack web development. Built multiple projects bridging frontend and backend technologies also including working with database systems
Projects
List of projects I have worked on.
Copenhagen based dog-food subscription webshop from the ground up using .NET Core, Vue.js, PostgreSQL, and Stripe
Open-source, cross-platform desktop app that monitors battery status and sends native notifications — built with Avalonia UI, 89+ GitHub stars.
A .NET Core web application for managing personal and group finances. Supports multiple workspaces so each person can track their own incoming and outgoing transactions separately — built as an open-source side project.
