About me
About CodeByMe
I am a full-stack engineer with a product focus. I design and build software that works in production: secure, maintainable, and ready to scale. I partner with teams and clients from initial validation through delivery, with clear goals, tight iteration, and defensible decisions.

How I work
I work with startups and SMBs that need to move forward without sacrificing quality. The flow is always the same: discovery, contract design (flows, API or data), incremental implementation, CI/CD delivery, and measurement in real usage. Small deliveries, short reviews, visible technical debt — no surprises at the end of the sprint.
Stack and architecture
On the frontend I use React, TypeScript, Vite, Tailwind, and Framer Motion when animation serves the content. On the backend Node.js with Fastify, REST or GraphQL depending on the case, Zod for contracts, WebSockets for real time, and queues or events when architecture demands it. On data: PostgreSQL, Redis, MongoDB, and Elasticsearch with explicit modeling and versioned migrations. On infra: Docker, Nginx, CI/CD, and AWS, with observability from day one.
Principles I apply
Intentional accessibility: readable contrast, visible focus, live regions where they matter. Conscious performance: reviewing images and bundles before adding visual polish. Honesty in copy: no invented metrics or promises I cannot defend in a technical interview or a commercial proposal. And real maintainability: data separated from components, explicit types, and documented changes when scope justifies it.
Who I work best with
Clients and teams that value clarity over blind speed, useful documentation over mandatory documentation, and traceability over heroism. If you are evaluating a hire or a project, you can review the selected work, read the Quality section, and contact me directly.
