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 ā 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.
How I Work
Audit the current system
I review the codebase, infrastructure, workflows, and bottlenecks before changing what already works.
Find the critical path
We focus on the changes that matter most: speed, reliability, maintainability, or business workflow impact.
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.
AI Features & Workflow Automation
I evaluate where AI adds real value, then integrate Claude or OpenAI into products and workflows for classification, content generation, and smart processing.
