1.1 — 1.3

1.1 We are a senior software consultancy for the systems an enterprise cannot afford to get wrong. Architecture work. JVM engineering in the Spring Boot and Jakarta EE traditions. AI integration into systems that already have to be reliable.

1.2 The model is deliberate: a single senior practitioner, no staff augmentation, no resellers. The engineer who scopes the work is the engineer who delivers it. Every architectural decision arrives with a written record of its alternatives, the trade-offs accepted, and the day it was made.

1.3 Engagements end the way they began — in a room, with a written record of what was changed and why. Long retentions are normal: the anchor engagement of the practice has run continuously since 2008.

Software architecture

The decisions that determine the shape of a system over the next decade — and the documents that hold them.

system	Service decomposition, integration, API contracts	→
legacy	Migration sequencing, replatforming, strangler patterns	→
review	Architecture review, remediation, ADR backfill	→

Anchor engagement · pan-German asset-management bank

A seventeen-year engagement spanning many phases of work for the bank: SEPA implementation; securities-order modernization (options, futures, new issues); customer-consultation tools; complaints management; sub-ledgers; process workflows. The most recent two years have focused on the bank's internal management platform — a Jakarta EE + Angular system that orchestrates everything arriving at the back office: customer correspondence (fax, email, tied-agent consultant channels), account creation, order entry, automatic order generation from incoming documents, four-eye control workflows, and end-to-end execution through the core banking system.

Electronic post-box integration · same bank

Designed and built as sole engineer: the bank's electronic post-box pipeline. Customers opting in to receive correspondence electronically have outgoing mail fetched from the bank's archive system, packaged and dispatched to an external German e-post infrastructure provider, with returned responses parsed and reconciled. A web application surfaces multiple conflict-resolution workflows for operations staff.

Clarity · Source 2 replay parser, in Java

A personal open-source project — a Java library for parsing Source 2 engine replays (Dota 2 and beyond), maintained continuously since 2014 and used across the competitive-gaming analytics ecosystem. Included here as a public code reference, not as engagement work — for anyone who'd like to read how I write performance-critical JVM code against an evolving binary format.

4.1 — 4.4

4.1

Senior, throughout.

Every engagement is led and executed by principals. No staff augmentation, no offshored discovery.

4.2

Decisions, written down.

Architectural decisions arrive with their alternatives, their trade-offs, and the date they were made.

4.3

Boring where boring works.

Proven tools by default. Novelty is reserved for the parts of the problem that genuinely need it.

4.4

Handover, not lock-in.

Engagements end with documentation and engineers on your side who can carry the work forward.
