I am a hands-on Software Engineer and Solution Architect with 17+ years of designing and running business platforms: multi-tenant SaaS, billing, IoT and ERP integrations. Since 2022 I have also built LLM systems that teams use every day, combining retrieval-augmented generation (RAG), hybrid search, tool-calling agents, evaluation and human approval steps. I own the whole path, from requirements and domain modelling through architecture, code, testing and CI/CD to deployment, observability and operations.
My work spans SME, product and enterprise environments. I communicate directly with clients and stakeholders, define technical requirements, plan delivery, and then build the software myself. Whether it is a Python backend, a cloud-native deployment, an Odoo customisation, or a multi-system integration, I handle it end-to-end. I write code daily and take full ownership of what I build.
Professional Journey
2008
→ 2013
Foundation
My career started in 2008 with backend development and automation in telecom and enterprise environments. I learned early how to build systems that run reliably under real operational pressure: integrating legacy systems, processing business-critical data, and supporting production workloads that couldn't fail. This foundation taught me that good software isn't just about clean code; it's about understanding how systems behave when things go wrong.
2013
→ 2018
Full-Stack & Platform Delivery
Over the next decade, I moved into full-stack delivery. I went from implementing backend components to owning complete service layers: APIs, integrations, database design, deployments and production operations. I worked with service-oriented and event-driven architectures, built mobile backends, led ERP integrations and delivered software across several client projects. I continued to write and deploy code daily. Architecture and system design became part of that engineering work, not a replacement for it.
2018
→ July 2026
Senior Engineering & Solution Architecture
From 2018 through July 2026, I worked end-to-end across backend, full-stack, cloud and Odoo projects for clients ranging from SMEs to larger product teams. I handled the full lifecycle: discussing requirements with clients, designing the technical solution, building and deploying the software, and supporting it in production. I wrote the code, managed deployments, integrated external systems, and solved real operational problems. Architecture and technical leadership remained a natural part of delivery, not a separate role detached from engineering.
Key Achievements
Designed and delivered 13+ production systems across SaaS, AI, IoT, ERP and commerce, with end-to-end ownership from requirements and architecture through deployment and support.
Designed and built AI features for QuotCraft, Midbel and VoltMol (RAG, hybrid search, tool-calling agents, guardrails and human approval) and for Hiork (LLM-assisted CV parsing and embedding-based candidate matching).
Built cloud-native Python platforms with FastAPI and Django, PostgreSQL, asynchronous workflows, Docker, Kubernetes, CI/CD and production observability.
Delivered multi-tenant billing, commerce and integration workflows connecting Stripe, Mollie, Odoo, registrar, DNS, hosting and external APIs with idempotency, audit trails and VAT compliance.
Designed an industrial IoT platform processing 100K+ sensor messages per day, enabling real-time telemetry, anomaly detection and predictive-maintenance workflows.
Hands-on lead of a seven-engineer team: wrote code daily, mentored colleagues and raised standards for architecture, APIs, testing and code quality.

Engineering Philosophy
I believe reliable systems are built through disciplined engineering, operational ownership, and pragmatic architecture decisions. My approach is grounded in:
Designing systems for production from day one: observability, monitoring, and failure modes are not afterthoughts
Writing maintainable code that survives team changes and scales with the business
Building platforms that solve real problems simply, avoiding unnecessary abstraction and over-engineering
Owning delivery end-to-end: writing and shipping code, managing deployments, and making pragmatic design decisions throughout.
Automating repetitive operational work so teams can focus on delivering business value
Treating infrastructure, CI/CD, and security as core engineering responsibilities, not separate concerns
Making data-driven decisions using metrics, SLOs, and production feedback loops
Mentoring engineers and raising technical standards through code review, documentation, and knowledge sharing
Choosing proven, stable technology over hype: reliability beats novelty in production systems
