What this site is for
This is the broad version of my work: a place for selected projects, short notes, and the technical interests that connect product engineering with systems thinking.

Projects
Commercial software, internal tooling, and long-running systems work
A small set of things I have built, shaped, or kept useful long enough to be worth writing down.
Notes
Short writing on performance, delivery, and engineering judgment
Working notes on the patterns, tradeoffs, and habits that keep paying off in real software.
Platform
Private infrastructure with an automation and operations bias
Homelab, access design, observability, and the operating side of building under `nosslin.dk`.
CV
The formal career read lives on its own page
Chronology, role history, and the recruiter-facing version of the story live there when needed.
About this site
Projects, notes, and systems work that are easier to explore than to summarize.
This homepage is meant to be a broad front door rather than a condensed evaluation page. It points toward the work, writing, and operating habits that shape how I build.
What tends to show up here
The recurring themes are performance, tooling, delivery quality, operational clarity, and the quiet engineering work that makes software easier to trust over time.
Where the explicit CV belongs
The homepage stays intentionally broad. If you want the formal career packaging, chronology, and recruiter-readable proof, that lives on the dedicated CV page.
Selected workSee all
Ampler Charts
A long-running commercial product shaped by performance work, runtime behavior, and practical product engineering.
Worked across implementation, performance, plugin behavior, profiling, caching, async processing, and practical C#/.NET design to keep it fast and dependable.
Office add-in platform and delivery tooling
Internal tooling and delivery work that made a commercial add-in environment easier to ship and maintain.
Improved CI parallelization, developer workflow, and supporting tooling so the team could move faster without making the product harder to operate.
NotesOpen notes
Performance work is product work
A note on why runtime improvements, profiling, and algorithm cleanup belong in the product conversation, not outside it.
Delivery leverage beats busywork
A note on the tooling, CI, and workflow decisions that quietly compound into a stronger engineering team.
Hands-on architecture
A working definition of architecture that stays close to code, operational detail, and product reality instead of drifting into theater.
