Loftwah's Tech Stack for 2025

2025 is shaping up to be another big year for me, and staying sharp means relying on a stack that’s battle-tested, productive, and just plain fun to use. This year, I’ve refined my toolkit with the tech I trust most for building, scaling, and experimenting. If you’re curious about what powers my projects, here’s a personal look at my tech stack for 2025.

Programming Languages

Some people stick to one language. I like to mix things up. Whether it’s scripting, backend, or systems-level work, I use the right tool for the job:

  • Python: My go-to for scripting, APIs, and diving into AI/ML experiments.
  • Node: JavaScript remains a powerhouse for server-side development.
  • Ruby: Clean, expressive, and perfect for Rails apps.
  • Rust: When I need safety, speed, and precision. No compromises.
  • Go: A joy to work with for scalable backends and CLI tools.
  • JavaScript/TypeScript: The workhorses of modern frontend and full-stack work.
  • Bun: I’ve been loving how fast and modern this Node alternative feels.
  • Uv: Optimising Python runtimes for performance where it matters.

Databases

Every great app needs a solid foundation. Here’s where I trust my data:

  • Postgres: Rock-solid, relational, and always reliable.
  • Redis: Lightning-fast caching and real-time storage.
  • SQLite: Perfect for local or lightweight embedded storage.

Backend Frameworks & Libraries

The frameworks that make building APIs and backend systems a breeze:

  • Rails: My first love. Still unmatched for rapid, full-stack development.
  • FastAPI: Blazing-fast Python framework for clean and performant APIs.
  • Sidekiq: Background job processing that just works.

Frontend Tools

Fast, modern, and clean frontend development keeps me happy:

  • Tailwind: Utility-first CSS for building beautiful UIs without the bloat.
  • Vite: Super fast frontend tooling that makes dev work seamless.
  • Astro: Modern static site generator for fast, content-driven websites.

Web Servers & Infrastructure

Where it all comes together:

  • Nginx: High-performance, rock-solid web server and reverse proxy.

Testing

Keeping things solid and bug-free:

  • RSpec: Ruby testing that feels natural.
  • Playwright: End-to-end testing that ensures my apps behave under pressure.

Cloud & DevOps

Here’s where I scale and automate everything:

  • AWS: My workhorse for cloud infrastructure.
  • DigitalOcean: When I need simplicity and speed.
  • Cloudflare: Performance, security, and CDN all in one.
  • GitHub/GitHub Actions: Code, version control, and CI/CD pipelines under one roof.
  • Terraform: Infrastructure as Code that keeps my cloud setup clean and repeatable.
  • Kamal: Rails deployment made simple with Docker.
  • Tailscale: Zero-fuss VPN for secure, private networking.
  • 1Password: Secrets, passwords, and sanity management.

AI & Analytics

I’m always tinkering with AI and staying observant with my apps:

  • OpenAI: Tapping into cutting-edge AI models (thanks, GPT!).
  • Anthropic: More AI power with Claude for advanced use cases.
  • Axiom: Observability done right for logs, metrics, and more.
  • Ollama: Local LLMs on my machine. No cloud required.

Operating System & Shell Tools

I live in the terminal, and these tools keep me efficient:

  • Ubuntu: The backbone of my dev and server environments.
  • Bash: Scripting and automating tasks like a pro.
  • nano: Lightweight editor when I need quick fixes in the terminal.

IDE & Editors

Where I spend most of my time:

  • VSCode: Lightweight, extensible, and perfect for just about anything I throw at it.

Containerisation & Orchestration

Portability, scalability, and simplicity:

  • Docker: The backbone of my deployments and development environments.

Monitoring & Load Testing

Keeping my apps healthy and resilient:

  • Prometheus: Metrics and alerts to keep an eye on performance.
  • K6: Load testing to make sure my apps don’t break under pressure.
  • Vector: A lightweight, ultra-fast tool for building observability pipelines

Final Thoughts

The right tools make all the difference, and this stack reflects the choices that keep me productive, curious, and excited about what I build. Whether it’s crafting APIs, scaling applications, or tinkering with AI, this setup has me covered for 2025.

If you’re working with a similar stack or are curious about anything I’m using, I’m always keen to chat tech and see how others are pushing the boundaries with these tools.
