Custom Fullstack Web Development

We build and maintain custom web applications, client portals, internal corporate platforms, and APIs. We pair fullstack software engineering with infrastructure expertise: writing strictly-typed modular code, designing scalable architectures, and deploying directly into production-grade infrastructure with automated CI/CD.

What We Do

  • Corporate Web Applications & Portals:

    • Client, partner, and B2B portals with granular Role-Based Access Control (RBAC).
    • Internal operations dashboards, order management workflows, and administration panels.
    • High-performance responsive user interfaces built with TypeScript, React, and Next.js.

  • APIs, Microservices & System Integrations:

    • Backend service development with Node.js (NestJS), Python (FastAPI), and Go.
    • Scalable REST, GraphQL, and gRPC API architectures with documented OpenAPI / Swagger schemas.
    • Integration with enterprise ERP platforms (1C:Enterprise, SAP), payment gateways, and third-party SaaS APIs.
    • Asynchronous task processing and event-driven streaming with RabbitMQ, Redis Streams, and Kafka.

  • Static Sites & Jamstack Platforms:

    • Lightning-fast corporate web platforms, documentation hubs, and blogs powered by Hugo and Astro.
    • Sub-50ms Time to First Byte (TTFB), high resilience to DDoS and traffic spikes without database overhead on the frontend.

  • Production Infrastructure & CI/CD Delivery:

    • Complete containerization with Docker and deployment across Kubernetes or Docker Compose.
    • Automated GitLab CI / GitHub Actions workflows: static analysis, unit/integration testing, and Zero-Downtime deployments.
    • Real-time observability: application error tracing with Sentry, Prometheus/Grafana metrics, and structured logging.

Technology Stack

  • Frontend: TypeScript, React, Next.js, HTML5, CSS3, TailwindCSS, Vite.
  • Backend: Node.js (NestJS, Express), Python (FastAPI, Django), Go.
  • Databases & Caching: PostgreSQL, MySQL, Redis, ClickHouse, SQLite.
  • Message Brokers: RabbitMQ, Redis Streams, Apache Kafka.
  • Jamstack: Hugo, Astro.
  • Infrastructure & CI/CD: Docker, Kubernetes, Nginx, GitLab CI, GitHub Actions, Sentry.

Outcomes

  1. Complete Codebase Ownership: Clean, modular, and typed source code stored in your company’s Git repository.
  2. Automated Release Workflows: Push-to-deploy CI/CD pipelines delivering updates without manual intervention or service downtime.
  3. Engineered for Scale: Optimized database query plans, multi-tier caching, and cloud-ready horizontal scaling.
  4. SLA-Backed Maintenance: 24/7 uptime monitoring, rapid incident response, and continuous feature delivery.
