I turn slow, fragile, and manual systems into fast, reliable software. I work with Next.js, Laravel, Payload CMS, APIs, automation, and practical AI integrations. I measure every improvement I ship.
I'm Mait Kaasik, a full-stack developer based in Estonia. Before software, I spent five years in professional kitchens; in 2019 I moved into development. Restaurant work taught me pace, discipline, and attention to detail. Those habits transfer directly to production code.
Today I build custom web applications and improve the performance, architecture, and reliability of existing systems.
Whether you need a new website, a faster database-heavy application, a dependable API, or automation that removes repetitive work, I cover the full stack: Next.js, Laravel, Payload CMS, and the infrastructure around them.
Years in Development
Projects Delivered
I focus technical work on three outcomes clients can feel: faster systems, less manual work, and AI that supports a real workflow.
Problem
Slow pages, reports, and background jobs waste time, especially when no one can see where the delay starts.
Approach
I measure the request or job end to end, isolate the expensive queries, network calls, or cache misses, and fix the bottleneck with the highest user impact.
Outcome
Faster load times, predictable reports, and performance work backed by numbers instead of guesses.
Problem
Important processes stall when data must be copied, files renamed, records moved, or tools checked by hand.
Approach
I connect the systems, add checks around the risky steps, and make the workflow observable enough to trust.
Outcome
Less manual work, fewer missed steps, and a process that keeps running on the busiest days.
Problem
AI pays off when the task is specific: classification, summarizing, drafting, routing, or review.
Approach
I define where the model decides and where a person verifies, design the prompts and fallback states, then wire it into the product or back-office flow.
Outcome
AI becomes a dependable part of one specific workflow, not a vague chatbot bolted on the side.
I start with traces, queries, logs, and the user-facing workflow, so we fix the cause instead of guessing.
We choose the smallest technical change that improves speed, reliability, or the daily workflow the most.
I ship the fix, compare the before and after, and document the system so the next improvement is easier.
Who I Help
I work with founders, small businesses, agencies, and product teams that need a dependable developer: someone who can improve an existing application, ship production features, connect tools, or remove performance bottlenecks.
Complete web applications from idea to production: frontend, backend, database, authentication, Payload CMS, deployment, and long-term maintainability.
I find and fix bottlenecks in slow pages, expensive database queries, caching layers, APIs, and background jobs, then verify the result with measurements.
I connect your tools, build reliable APIs, and replace repetitive manual work with processes that run on their own.
I evaluate where AI genuinely adds value, then integrate Claude or OpenAI into products and workflows for classification, drafting, routing, and smarter processing.
