Services

I help fintech firms build and maintain the systems they rely on every day. Areas of focus include:

• Backend development, trading infrastructure, and system automation
• Secure integrations with brokers and data providers
• MVP development for new product launches
• Data conversion, customer onboarding, and process optimization
• Long-term support, including maintenance of legacy platforms

Whether you're launching a new SaaS product or running a live trading platform, I deliver secure, compliant, and production-ready systems tailored to your needs.

Example Engagement

One of my clients operates a live signal trading platform. I am responsible for development, feature delivery, hosting, infrastructure, uptime monitoring, and ongoing support.

This is not a short-term project. I remain involved as the platform evolves, providing long-term technical leadership and hands-on execution.

What I Help You Achieve

When you partner with me, you gain:

• Accelerated Launch & Reduced Risk: Rapidly deploy secure, production-ready MVPs, reducing your time-to-market and compliance risks from day one.
• Optimized Operations: Automate complex workflows and streamline processes, enhancing efficiency and reducing operational overhead.
• Scalable & Resilient Systems: Build high-performance, fault-tolerant platforms designed for growth and unwavering reliability.
• Strategic Resource Optimization: Gain comprehensive backend, infrastructure, DevOps, and compliance expertise in a single engagement, avoiding unnecessary hiring overhead.
• Freedom from Lock-in: Ensure long-term maintainability and evolution of your systems, including legacy platforms, with full code ownership and no vendor dependence.

Independent, Experienced, Professional

I offer the senior-level expertise and professionalism of a fintech consultancy, delivered with the speed and personal accountability of a solo partner.

• Over 25 years in software engineering
• 15 years dedicated to financial technology
• Deep background in full-stack systems, distributed architecture, and regulated environments
• Personal, fast communication and consistent delivery
• No subcontracting, no handoffs

You work directly with me. I am selective, taking on only two active clients at a time to ensure focus and quality.

Built for Regulated, Real-World Environments

Systems are designed from the start to meet the expectations of regulated industries:

• Support for DORA, AML, and KYOC standards
• GDPR-aligned privacy features including data minimization, access logging, and consent tracking
• Role-based access control, secure audit trails, and long-term data retention
• Optional penetration testing and OWASP-based security practices
• Monitoring, alerting, backup strategies, and full operational observability

Whether your business needs to pass an audit, meet investor due diligence, or protect customer data, compliance is embedded in the foundation.

Technical Capabilities

I deliver software systems end-to-end, from architecture to production rollout.

• Secure multi-tenant platforms with data isolation and white-labeling options
• High-throughput, fault-tolerant, and low-latency distributed systems
• Production-grade MVPs with authentication, admin panels, reporting, and partner integration hooks
• Data onboarding pipelines and transformation tools
• Backend-heavy systems with optional collaboration on UI/UX

Platforms are built using Java (Spring), Flutter, and TypeScript, and deployed on AWS, Azure, or bare metal depending on your preference.

Development Practices

• Clean, testable, and maintainable code using Git and CI/CD
• Google Java Style Guide for clarity and consistency
• Secure protocols including REST, SOAP, Protocol Buffers, and ActiveMQ
• DevOps workflows for monitoring, deployments, and versioning
• Infrastructure handover, documentation, and developer training available

Every deliverable is documented, reviewed, and structured for long-term reliability. I stay available for ongoing support, fixes, and roadmap development.

Engagement and Pricing

You do not pay for anything you do not need. Engagement models include:

• Fixed-fee for clearly scoped work
• Monthly retainers for ongoing development and support
• Revenue share models in aligned cases - structured through a separate agreement.
• Optional legal and operational protections such as escrow, documentation, and phased handovers

I encourage starting small. A focused initial engagement allows us to build trust and validate working style before expanding.

Risk Mitigation & Long-Term Partnership

Your peace of mind is paramount. I ensure:

• Full IP & Infrastructure Ownership: You retain 100% ownership of all code, infrastructure, and documentation from day one.
• No Vendor Lock-in: My commitment includes full technical handover, complete access, and developer training, ensuring your team can manage and extend the systems independently.
• Ensuring Continuity & Support: Unlike short-term engagements, I offer ongoing support, roadmap development, and dedicated care for your systems, including legacy platforms. I don't disappear.
• Flexible Protections: Optional escrow agreements and phased delivery models provide additional legal and operational safeguards tailored to your needs.

Build Secure Financial Infrastructure - Together

I design and support production-grade fintech systems with a focus on security, compliance, and long-term reliability.

If you're launching, modernizing, or scaling financial infrastructure, and need a trusted technical partner who understands regulated environments, I’d be glad to connect.

I work with lean teams that want senior-level delivery without unnecessary overhead or vendor lock-in.
