Why Tech Stack Selection Matters More Than Ever

Choosing the right technology stack is one of the most consequential decisions in enterprise software development. The wrong choice can lead to scalability bottlenecks, security vulnerabilities, and mounting technical debt. In 2026, the technology landscape offers more options than ever — making informed selection critical for long-term success.

At Nexis Limited, we've built SaaS products and enterprise systems across Go, Rust, Python, and TypeScript — giving us firsthand insight into where each technology excels.

Backend Technologies

Go (Golang) — For High-Throughput APIs

Go has become our primary choice for new backend services. Its compiled nature, built-in concurrency with goroutines, and minimal memory footprint make it ideal for microservices and API-heavy applications. We use Go with the Gin framework for products like Bondorix, where handling hundreds of concurrent logistics operations demands consistent sub-millisecond response times.

Rust — For Performance-Critical Systems

When you need bare-metal performance without sacrificing safety, Rust is unmatched. We use Rust for specialized systems like medical imaging processors (PACS/DICOM handling) where processing large binary files with zero-copy semantics and memory safety is non-negotiable.

Python (Django/FastAPI) — For Rapid Development

Python remains the fastest path from idea to production for many business applications. Django's batteries-included approach is ideal for HR systems, e-commerce backends, and content management. FastAPI brings Python into the high-performance API space with async support. Our Ultimate HRM and Digital School products are built on Django.

Frontend Technologies

React 19 + TanStack Start

React continues to dominate the frontend landscape, and React 19 brings server components, actions, and improved streaming SSR. TanStack Start is our choice for new projects — offering type-safe routing, server functions, and a modern DX that outpaces traditional Next.js for certain use cases.

Next.js — For Content-Heavy Applications

For marketing sites, blogs, and applications where SEO and static generation are priorities, Next.js remains the gold standard. Its Image optimization, built-in routing, and mature ecosystem make it reliable for production use.

Database Selection

PostgreSQL — The Enterprise Default

PostgreSQL is our default database across all products. Its reliability, ACID compliance, JSON support, full-text search, and extension ecosystem (PostGIS, pg_cron, pgvector) make it suitable for virtually any application. We pair it with Redis for caching and real-time features.

Infrastructure and DevOps

  • Docker + Kubernetes: Container orchestration for consistent deployments
  • Terraform: Infrastructure as Code for reproducible environments
  • GitHub Actions: CI/CD automation with self-hosted runners
  • Prometheus + Grafana: Monitoring and alerting stack
  • MinIO: S3-compatible object storage for on-premise deployments

Making the Decision

There's no universal "best" stack — the right choice depends on your domain, scale requirements, team expertise, and timeline. Our recommendation: start with the simplest technology that meets your current needs, and design your architecture to allow component replacement as requirements evolve.
