I'm a Fullstack Engineer with 4+ years of commercial experience building integration-heavy web products. I work across backend architecture, frontend applications, data, infrastructure, security, and delivery — from the first schema and API contract to production monitoring.
My strongest areas are fintech and payments, SaaS platforms, real-time systems, third-party integrations, and AI-enabled products.
- Design APIs, services, background jobs, queues, and integration boundaries
- Build customer-facing products and internal operational tools
- Own authentication, billing, webhooks, failure recovery, and observability
- Ship through Docker-based environments, CI/CD, tests, code review, and smoke checks
Most of my production work is private. The case studies below intentionally describe the engineering scope without exposing client, company, product, or repository names.
| Domain | Engineering scope |
|---|---|
| Fintech & payments | Core API and gateway services, seven operational web panels, payment order lifecycle, provider routing, callbacks and webhooks, JWT access zones, background workers, deep-link/card/SBP flows, rate limiting, SSRF protection, allowlists, metrics, logs, smoke tests, and recovery automation. |
| Commerce platforms | Multilingual Next.js storefronts, carts and checkout flows, admin tooling, PostgreSQL-backed services, Shopify Storefront and Customer Account integrations, transactional email, and messaging integrations. |
| Compute infrastructure | GPU rental workflows with external provider integrations, per-minute billing, job orchestration, PostgreSQL, Redis, Celery, and customer/admin interfaces. |
| AI media products | Music and voice SaaS platforms with authentication, credits, subscriptions, payments, email flows, third-party model APIs, and containerized deployment. |
| Layer | Tools and practices |
|---|---|
| Frontend | TypeScript, React, Next.js, Vue.js, Tailwind CSS, state management, SSR, accessible responsive UI |
| Backend | PHP 8 / Symfony, Node.js / NestJS, Python / FastAPI, REST, WebSocket, queues, workers, integrations |
| Data | PostgreSQL, Redis, Prisma, EF Core, migrations, transactions, indexing |
| Delivery | Docker, GitHub Actions, CI/CD, Vercel, Linux, structured logging, metrics, health checks |
| Quality & security | Playwright, unit/e2e tests, code review, JWT, rate limiting, allowlists, SSRF-safe integrations |
| Project | What it demonstrates | Stack |
|---|---|---|
| gradient-back · live demo | Interactive WebGL gradient with custom shader animation and pointer-driven effects | React, React Three Fiber, GLSL, Vite |
| space-station-14-soyuz | Work with a large open-source multiplayer codebase, content systems, builds, and community development | C#, .NET, ECS |
| Labs | Desktop and data-layer engineering with documented setup and tests | C#, WPF, WinForms, EF Core, SQL Server, Docker |
- Own the vertical slice. Data model, API, UI, integration, release, and monitoring belong to one coherent solution.
- Design for failure. Timeouts, retries, idempotency, auditability, recovery paths, and useful logs are part of the feature.
- Keep boundaries explicit. Clear contracts and isolated adapters make payment providers and external APIs replaceable.
- Use AI with engineering discipline. AI tools accelerate research and implementation; tests, review, and production evidence decide what ships.
I'm open to remote Fullstack, Backend, and Product Engineer roles where I can own meaningful systems and ship measurable product value.
