Performance-focused Full-stack Developer

Mait Kaasik. The Almighty Developer.

I build and optimize Next.js, Laravel, and Payload CMS applications so slow queries, fragile workflows, and unreliable systems become fast, stable, production-ready software.

About Me

Hey! I'm Mait Kaasik, a full-stack developer. In 2019, I left my chef career behind and dove into the world of programming. Years in professional restaurant kitchens taught me both discipline and attention to detail – qualities that are important in both the kitchen and in code.

Today I create custom web solutions and improve the performance, architecture, and reliability of existing applications.

Whether you need a new functional website, a faster database-heavy application, a reliable API, or automation that removes manual work, I help bring it to life with Next.js, Laravel, Payload CMS, and the surrounding infrastructure.

Examples of My Work

A selection of projects built for real users, real constraints, and measurable results.

What I Can Build or Improve

Who I Help

Best fit for founders, small businesses, agencies, and product teams that need a dependable developer to improve performance, ship features, connect tools, or modernize an existing app.

Your application is slow, unstable, or difficult to maintain
You need a production-ready website, API, automation, or internal tool
You want AI or workflow automation that solves a real business problem

How I Work

01

Audit the current system

I review the codebase, infrastructure, workflows, and bottlenecks before changing what already works.

02

Find the critical path

We focus on the changes that matter most: speed, reliability, maintainability, or business workflow impact.

03

Build, measure, and document

I ship the improvement, verify the result, and leave the system easier to understand than I found it.

Full Stack Web Development

Complete web applications from concept to production: frontend, backend, database, authentication, CMS, deployment, and long-term maintainability.

Performance & Database Optimization

I find and fix bottlenecks in slow pages, expensive database queries, caching layers, APIs, and background jobs, then measure the result.

Automation & API Integrations

I connect your tools, build reliable APIs, remove repetitive manual steps, and make complex business processes run on their own.
