Full-stack developer for products that need frontend, backend and infrastructure in one pair of hands.
I build, repair and ship web products, admin panels, APIs, automations and integrations for founders, agencies and small teams.
Available for one 15-20h/week contract. Paid production audits start at $750.
Dmitry Galaktionov (Galionix): full-stack, backend and infrastructure developer
I am useful when the project is messy, the deadline is real, and somebody needs to own the path from product problem to shipped software.
I also publish as Galionix. Search aliases: Dmitry Galaktionov, Dmytro Galaktionov, Dimas Galaktionov, Дмитрий Галактионов and Дмитро Галактіонов all refer to the same developer and this website.
Turn a product idea into a working Next.js/React app, backend API, database model, deployment and a clear handoff.
Design API routes, data models, auth, third-party integrations, queues, webhooks and reliable service boundaries.
Build operational dashboards, role-based admin flows, tables, forms, reports and moderation interfaces for real teams.
Enter an unstable codebase, map the moving parts, fix blockers, add tests/monitoring and make the next release realistic.
Support agency or design-studio delivery with Next.js, backend APIs, admin panels, integrations and deployment behind your team or directly with the client.
Help a founder turn a product idea, prototype or half-built app into a working product with backend, auth, database and a release path.
Build dashboards, role-based workflows, integrations, reports and automations for teams tired of spreadsheets and manual status work.
React, Next.js, TypeScript, Node.js, APIs, Supabase/PostgreSQL, integrations and infrastructure cleanup for contract or remote teams.
Commercial proof
I engineer high-throughput data pipelines, cloud services, and production web applications: from automated customs declaration OCR and CleanTech servicing to multi-tenant compliance platforms.
I can work across UI, API, database, deployment, CI/CD, monitoring and documentation instead of dropping one isolated piece.
Recent work includes Next.js, React, TypeScript, Supabase/PostgreSQL, Zod, RTK Query, Playwright, Sentry and PostHog.
I turn unclear requirements into a technical plan, name risks early and keep the implementation tied to business value.
A useful engagement can start as a short audit, rescue sprint or scoped build before turning into larger work.
Featured Engineering & Production Cases
Production platforms built with strict type safety, resilient asynchronous queues, and real-world compliance standards.
