Clarity of thought
I like reducing a complicated problem until the important decisions, trade-offs and failure modes are visible to the team.
Veteran Systems Engineer based in Berlin
Architecting backend systems that are ergonomic to build, run and extend.
Systems engineer with a decade of experience across finance, aviation, security, warehouse systems, cryptocurrency and SaaS. I work best around complex product lines where the challenge is not only to build the system, but to make it understandable enough for teams to own.
How I work
I build systems so the next engineer can move with confidence.
Systems view
I work through services, events, data, infrastructure, delivery and operations as one connected system instead of isolated parts.
Thinks beyond the obvious path
I enjoy finding a simpler or more ergonomic route when the default solution would add more process, boilerplate or long-term friction.
Connects the dots
I am comfortable entering systems where no single person knows every layer, then building a shared technical model the team can use.
Platform design
I care about abstractions that remove boilerplate and foundation work so developers can focus on the business behavior they are responsible for.
Pragmatic delivery
I try to keep the solution useful in production: observable, testable, deployable and understandable after the first version ships.
Open source projects
Key highlights from my open-source work.
Native backend
Java backend work for Mitbauen with native-oriented delivery and backend foundations for a civic collaboration product.
Database tooling
Reflection-free database migration engine with build-time SQL compilation, generated Java metadata, migration catalogs and impact reports.
Developer tooling
Maven plugin work for making Java projects friendlier to GraalVM native image builds by generating service metadata ahead of runtime.
Runtime visibility
Plug-and-play module for Nano applications that exposes runtime events, logs, system metrics, JSON endpoints and a minimal HTTP UI with GraalVM compatibility.
Network security
Lightweight HTTP/HTTPS proxy for Raspberry Pi with live traffic visibility, request classification, local persistence and blocking controls.
AI Transaction Explainer
Static transaction explainer for Bitcoin and Ethereum with a Cloudflare Worker proxy, AI summaries, shareable URLs and rate limiting.
Engineering track record
Professional experience.
Software Engineer III | Foundry Digital
- Designed high-performance Kotlin/Spring Boot services for financial and blockchain-adjacent infrastructure, with secure credential retrieval through AWS Secrets Manager and caching to reduce external dependency latency.
- Refactored high-throughput Kafka consumer pipelines with semaphore-based backpressure, batch database upserts and Testcontainers coverage so financial event processing stayed deterministic under load.
- Automated ledger-style reconciliation using scheduled jobs, transactional boundaries, JPA/Hibernate and MySQL, saving 16+ hours each week in manual operational effort.
- Architected and containerized an end-to-end payments testing framework with GitLab CI coverage reporting, raising quality standards across distributed transaction flows.
- Implemented Datadog APM across services, correlating logs, traces and metrics to monitor critical financial infrastructure and detect anomalies earlier.
Senior Software Engineer | SHS Viveon AG
- Implemented Keycloak-based SSO with OIDC, ID tokens, claim mappers and Spring JWT validation, including back-channel token exchange to avoid front-channel token exposure.
- Resolved high-severity CVEs by upgrading Gradle dependencies, replacing insecure transitive libraries and adding Snyk-driven CI security gates.
- Optimized Hibernate performance by removing N+1 queries, adding composite indexes and enabling batch writes to reduce query latency and improve throughput.
- Built MR-triggered GitLab CI pipelines with semantic versioning, Docker image builds, Helm chart updates, readiness probes and automated rollback mechanisms.
Senior Engineer | Deutsche Bank
- Engineered type-safe Kotlin DSLs for payment orchestration and compliance rules, compiling definitions into executable Spring components and reducing scattered boilerplate.
- Designed regulatory payment flows across Kotlin/Spring Boot microservices with idempotency, deterministic retries, correlation IDs and full audit trails.
- Improved compliance and reporting data integrity through root-cause analysis of redundant datasets and high-volume ClickHouse query optimization.
- Worked with distributed engineering, compliance and business teams to clarify operational constraints, make trade-offs explicit and reduce rework early.
Senior Java Engineer, Trade Finance | Modifi
- Designed a production-grade invoice management microservice with Java, Spring Boot, PostgreSQL and JPA/Hibernate, using idempotency keys and strict transactional boundaries.
- Refactored shipment tracking with modular architecture, structured logging and resilient retry logic for external Seagate API integrations.
- Improved GitLab CI/CD with automated quality gates and environment-specific workflows, then added Grafana dashboards for real-time operational visibility.
- Documented best practices, improved onboarding and contributed to shared architecture and coding standards so delivery quality was easier to maintain.
- Mentored colleagues and peers to keep the bar high across day-to-day engineering delivery.
Senior Consultant, Aviation | Infogain / Solunus
- Modernized airline seat-management microservices, improving scalability and real-time seat availability across global booking channels.
- Upgraded legacy services to Java 11, moved Docker images to Alpine Linux and right-sized containers to reduce infrastructure cost and security exposure.
- Implemented a custom distributed logging and tracing framework with Logback, improving observability and cutting incident resolution time.
- Automated Jenkins pipelines with quality gates, test stages and environment-specific build steps to improve deployment reliability and engineering efficiency.
Senior Developer, Security Systems | ICREST
- Re-engineered a high-volume ingestion pipeline with operational tuning controls that adjusted ingestion rates by data density, improving throughput by 80%.
- Migrated features from a legacy Java EE application toward Spring Boot to make the platform easier to evolve.
- Built automated QA and regression testing to improve release reliability, shorten iteration cycles and reduce manual validation.
- Drove backend scalability improvements for secure identification and verification systems, reducing operational workload and strengthening performance for growth.
Sr. Project Engineer | Wipro Ltd
- Designed Java 8 and Spring Boot microservices to process device data for smart systems.
- Partnered with business teams to extend mobile computing capabilities, enabling new client use cases in a distributed microservices environment.
Co-Founder | YoTech Softwares Pvt. Ltd
