Architecture & project structure

I design the technical foundation of your product: stack, folder structure, data models, APIs, integrations and user flows - built for scalability, security and maintainability.

Start your project

What architecture planning covers

✓Technology stack recommendation (frontend, backend, database, hosting)
✓System diagram: modules, services, third-party integrations
✓Data models, API contracts and authentication approach
✓Performance, caching and scalability considerations
✓Security baseline: HTTPS, roles, secrets, backup strategy
✓Repository structure and deployment environment map

How I approach system design

Architecture follows the product concept - no over-engineering for an MVP, no shortcuts that block growth six months later.

I document decisions so your team (or future developers) understand why PostgreSQL was chosen over MongoDB, or why Astro fits this marketing site.

For e-commerce and SaaS I plan payment webhooks, admin roles and audit trails early.

Polish and EU projects often need GDPR logging, cookie consent hooks and EU-region hosting - these are part of the structure, not an afterthought.

US-facing products get architecture notes for SOC-friendly practices, CDN edge locations and timezone-safe job queues where relevant.

About me

I'm Viktar Liukevich

Full-stack developer · 15+ years creating web

Good architecture saves money. I have seen projects rebuilt because nobody planned APIs or database relations at the start - I prevent that with clear structure up front.

Based in Warsaw, I work with clients across Poland, Europe and the USA, choosing pragmatic stacks: React, Astro, Laravel, Node, PostgreSQL, Docker and cloud hosting that match your budget.
