Software Architect · Riga, Latvia

I make complex backend systems easier to change.

I design and modernize business-critical platforms across fintech, payments, e-commerce, identity, and integration-heavy products — while staying close to implementation.

What I bring

Architecture for systems that have to keep moving.

I work best where technical depth, product reality, and operational risk meet.

01

Platform architecture

Distributed backends, modular services, APIs, event-driven systems, workflow engines, and integration hubs.

  • Node.js & TypeScript
  • PHP, Laravel & Symfony
  • PostgreSQL & Redis
02

Modernization

Pragmatic decomposition of legacy systems with controlled risk, observability, and uninterrupted product delivery.

  • Monolith to modules
  • Reliability & security
  • CI/CD & operations
03

Fintech & integrations

Payment platforms, SEPA, identity, regulated products, and the third-party integrations that make them useful.

  • Payments & fintech
  • OAuth2 / OIDC
  • Automation & orchestration
04

Technical leadership

Clear architecture decisions, hands-on delivery, mentoring, and communication across engineering and product.

  • Technical strategy
  • Roadmap ownership
  • Cross-functional delivery

Selected work

Complexity reduced to a system people can operate.
