About
After 20+ years of building and leading software teams, I am now offering my experience as a freelance Fractional CTO and Senior Software Architect.
I am also the Solo Founder of Tylium, where I am building a high-performance audio software ecosystem based on Rust and Next.js. I remain deeply hands-on.
My focus is on part-time and short-term missions for startups and SMEs, where I can help you:
- Define and scale your product architecture (SaaS, FinTech, Microservices)
- Mentor and level-up your development team
- Tackle complex technical debt and solve urgent, complex problems
My core expertise is in Java/Spring Boot microservices, high-performance Rust, and full-stack Next.js. I provide strategic leadership that is practical, modern, and backed by code.
Services Offered
Providing part-time technical leadership, strategic planning, and technology roadmapping for startups and SMEs.
Designing scalable, secure, and maintainable systems, particularly for SaaS, FinTech, and Microservice-based applications.
Coaching development teams, instilling best practices, and conducting design and code reviews.
Expert-level development in Java/Spring, Rust, and Next.js for complex projects.
Auditing existing systems, advising on technical debt, and providing solutions for scaling and performance.
Experience
As my primary ongoing passion project (parallel to my freelance consulting), I am independently architecting and engineering a complete, end-to-end ecosystem for audio/MIDI software.
- High-Performance Rust Backend: Architected and built a large-scale Rust monorepo for real-time audio/MIDI processing, including a VST3 plugin host, a modular event-processing engine, and cross-platform I/O libraries.
- Specialized Audio UI Framework: Engineered a performance-first React/TypeScript component library using modern CSS and SVG to ensure fluid rendering under heavy CPU load from audio processing.
- Full-Stack E-commerce Platform: Built the complete commercial web platform (marketing, blog, e-commerce) using Next.js, Vercel, Stripe, and a serverless Postgres DB.
My personal consulting company (founded in 2018) through which I conduct all freelance, consulting, and entrepreneurial activities, including my work as a Fractional CTO / Architect and the Tylium projects.
As CTO, I led the technical strategy during the company's transition from a monolithic startup to a collaborative, multi-team scale-up.
- Led the re-evaluation and modernization of development, L2 support, and delivery processes.
- Initiated and led aggressive strategies to address significant technical debt across all tiers.
- Oversaw major new feature releases and launched the company's first fully digital, zero-touch customer onboarding process.
- Coached and mentored the next generation of the company's technical leaders.
As a foundational architect and hands-on developer, I built the core of the FinTech SaaS platform.
- Personally designed and coded complex business modules from scratch, including Google Sheets-like financial forecasting editors and a custom KPI engine.
- Architected the platform's critical multi-tenant security and tenant management model for global scalability, fine-grained access control, and white-labeling.
- Led the complete architectural overhaul of the main reporting module, dramatically increasing performance.
- Led the "Red" team, fostering an Agile spirit and helping grow the company's development talent.
As a consultant, I led architecture on two key client projects:
- FinTech: Architected the initial backend for the "DigiTeal" payment modernization product using Spring Boot, Spring Security, and JPA, integrated with an AngularJS front-end.
- GovTech (SOA): Served as an SOA Expert for the Federal Public Service of Finance, enhancing their ESB infrastructure and managing web services security (SOAP, WS-Security), auditing, and monitoring.
I managed the architecture team (3 Architects, 2 Engineers) for "Soliam," a massive (3M+ LOC) asset and wealth management application.
- Faced with 10+ years of technical debt, I created and defended a multi-year architectural roadmap to modernize the monolith to a modern, middle-tier, object-oriented architecture with a path to an HTML5 UI.
- Led a cross-department Scrum team to build a new, generic data injection/extraction framework.
- Acted as a key technical expert in the pre-sales process, helping to secure a major contract with Natixis.
As a member of the central Technology R&D department, I built and supported the in-house Java/EE frameworks used by all product teams.
- Co-developed the in-house BSB-JF (Java/EE) and BSB-SF (Service-Oriented) frameworks, including maintaining an Hibernate-like ORM framework.
- Led R&D teams to build key reusable components (Job Execution Engine, Document Management interface).
- Authored a 100-page "Comparative Study of Enterprise Service Buses," leading to the company adopting FUSE ESB.
- Provided internal training on frameworks and led technical interviews.
I joined this startup to establish its Software Development Department from scratch.
- Led the pre-study, wrote the bid, and won the project for a new enterprise software for Home Care Services.
- Single-handedly designed and built the entire application (124,000+ LOC) using early EJB3 with JPA/Hibernate and Eclipse RCP.
My first professional role. I was responsible for the end-to-end development of the cardiology department's modules for the in-house medical record software, re-engineering a system from an original Filemaker record.
