Senior Software Engineer · Solutions Engineer

Software that ships fast.
And still maintainable tomorrow.

Ship fast. Learn fast. Iterate fast. Measurable value at every step. Six-plus years of enterprise delivery and hands-on work with current AI tooling. Both at once: speed and architecture that holds up, engineering discipline and AI used with intent.

How I work

Full Stack Engineer

Backend through interface

I build complete systems: Java/Kotlin or Python on the backend, Vue 3 or Angular on the frontend, Docker and OpenShift in the infrastructure.

  • REST APIs, microservices, BFF pattern
  • Vue 3, Angular, TypeScript
  • Python / FastAPI, Java / Spring Boot

Solutions Engineer

Systems that fit the problem

I take requirements from the business side and translate them into architecture that ships, scales, and stays maintainable.

  • Microservice and integration architecture
  • Legacy integration (IBM MQ, Oracle, Axway)
  • CI/CD design, quality gates, standards

Senior Engineer / Lead

Delivery and enablement

I own architecture decisions, onboard new team members, and set practices that outlive the project.

  • Technical coaching and code review
  • Scrum / SAFe, cross-functional collaboration
  • Standard-setting (CI/CD, security scans)

AI Integration

AI as a tool, not a promise

I integrate AI where it concretely helps: as a context-aware assistant, an automation layer, or smart routing between models.

  • LLM integration (local and cloud)
  • Workflow automation with AI components
  • Privacy-compliant on-prem setups

AI fluency as a cross-cutting skill

I'm a software engineer who understands AI tools and uses them in production. That means a realistic read on what LLMs can and can't do, clean integration with existing systems, and the ability to bring a team along.

What I deliver

01
Greenfield

Build new systems

From requirement to production: architecture, implementation, deployment. Full stack or focused on backend or frontend, depending on the gap. Maintainability and scalability built in from day one.

02
Brownfield

Evolve existing systems

Pay down technical debt, modernize architecture, integrate legacy systems. I know enterprise stacks and how to protect existing investments while moving forward.

03
AI Integration

Integrate AI where it counts

Assess where AI brings real value in an existing system. Implement LLM features: local or cloud-hosted, privacy-compliant, embedded in existing workflows. Not bolted on. Real integration.

04
DevOps / CI/CD

Set up delivery infrastructure

CI/CD pipelines, quality gates, deployment automation. I build toolchains that make teams permanently faster and safer. Already established as the delivery standard for complex enterprise accounts.

Selected work

Own startup · 2025EXIST-funded

Built a full observability platform as a founding project

Full-stack development, AI integration, productization: from idea to government grant

What we built

A time-series-native observability platform (Vue 3 / Python / FastAPI) with configurable widgets, FQDN-based data sources, BFF auth pattern, and a no-code early-warning system.

AI component

An autoencoder trained on customer data spots anomalies and triggers incident triage. A multi-agent LLM system classifies the incidents and produces traceable explanations. A model-agnostic gateway runs local inference: privacy-compliant, with no changes to application logic.

Outcome

Production-ready platform, EXIST federal grant approved. Technical responsibility within the founding team for architecture, backend, frontend, auth, and AI integration.

Underwriting workbench: complex policy work without context-switching

Digital workspace for mid-market property underwriters and international team collaboration

Starting point

Underwriters worked across distributed systems with no straight-through integration. Local and international teams coordinated through manual handoffs. Rekeying between systems cost time and produced errors. The focus on the actual complexity of policy work got lost.

What I built

An integrated underwriting workbench. From requirements work with the business side through to production. System jumps eliminated through unified workflow integration. Shared workspace for local and international teams, embedded in existing underwriting processes without parallel structures.

Outcome

Underwriters can focus on the actual complexity of policy work instead of on system switches. Smooth collaboration across sites. Full delivery responsibility: requirements, architecture, implementation, go-live.

Enterprise IT consultancy · Financial Services · 2022–2025Lead Engineer

Built a CI/CD toolchain from scratch, adopted as delivery standard

Microservice delivery for a reinsurance client in a regulated environment

Starting point

No automated delivery process. Releases were manual, inconsistent, and error-prone. The project had to build engineering discipline while shipping at the same time.

What I built

SemVer hooks → CI builds → artifact registry → container deployment with quality and security gates wired in. Scalable microservice architecture with message queues, API gateways, and identity management.

Outcome

Toolchain adopted as the standard for every follow-up project. Promoted to Lead Engineer after eighteen months. Business-rules engine integrated, business team enabled to extend it on their own.

BI consultancy · Pharma · Drug Safety · 2019–2022BI Consultant

Drug interaction analysis for vaccines in development

SQL, ETL, data modelling, and reporting in Cognos and Tableau

Question

Which existing drugs interact with a vaccine in the development phase? The answer was in the data. It just had to be made structured and queryable.

What I contributed

Wrote the SQL queries that surfaced relevant interaction patterns from Oracle source data. Designed the ETL pipelines and the underlying data model. Built the reporting environment in Cognos 11 and Tableau for the domain team.

Context

Drug safety data in a regulated pharma environment: precise queries and a clean data model are not optional, they are the prerequisite. The work required close coordination with the domain experts to translate the right questions into database logic.

Oracle database analysis as the foundation for a clean cloud migration

Migration prep for a grown database landscape in a regulated environment

Starting point

A grown Oracle database landscape was set for cloud migration. Unclear: which objects were migration-critical, where the data model needed reworking.

What I built

A term-frequency matrix across DDL and PL/SQL source code that surfaces dependencies and usage frequency. On top of that: a joint reassessment of the data model with the domain team.

Outcome

Clear prioritization of migration-critical objects, a reworked data model as the foundation. Not lift-and-shift with old debt, but a structured restart in the cloud.

Lunch break

This site (architecture, components, i18n scaffolding, A11y pass, mobile navigation) was built with AI assistance during a single lunch break. The tools write code. The architecture, the trade-off calls, the question of what to build at all: that stays human work. Six years of enterprise delivery before this current tool cycle make the point: I deliver without AI too. With AI I'm just faster.

Speed without judgment is just noise.
