Realight Dev
AI‑Accelerated Fullstack App Developer
I build production‑ready apps with AI‑boosted speed and senior‑level quality.
End‑to‑end development of mobile and web applications – from first idea and UX concept to a tested, deployed product in the App Store, Google Play, or on the web.
Available for new projects: concept‑stage, MVPs, and rebuilds of legacy tools.

Maintenance & feature evolution
I work as a fullstack product developer: you bring the problem and the desired outcome, I take care of architecture, implementation, integration with third‑party services, and getting your app into the hands of real users.
- Architecture & planning – translating business ideas into a concrete tech plan.
- Implementation – mobile, web, backend, and integrations.
- UX‑oriented delivery – clean, predictable user flows.
- AI‑assisted execution – using Cursor and modern AI tools to move faster without sacrificing code quality.
- Launch support – store publishing, hosting setup, basic monitoring.

How we work together
Clear, product‑oriented collaboration from first call to launch.
Discovery call (30–45 minutes) – clarify idea, users, and success criteria.
Scope & proposal – concise plan with phases, timelines, and stack.
Build in iterations – short cycles with visible progress and regular
demos.
Testing & polish – functional tests plus UX refinement.
Launch & handover – store publishing / web deployment, plus
technical documentation.
Throughout the project I use AI tools (including Cursor) to accelerate coding, refactors, and documentation, while keeping all key architectural and product decisions human‑driven.
You always know what is happening: milestones, what is done, what is next, and what is needed from your side (content, domain rules, approvals).
Let’s talk about your app
Briefly describe your idea, target users, and timeline – you’ll get a concrete proposal.
Send a short message with:
- 1–2 sentences about your product idea.
- Who will use it (internal team, customers, public users).
- Preferred platforms (iOS, Android, Web) and deadline.

Frequently Asked Questions
Common questions about working with Realight Dev.
How long does a typical project take?
Timeline depends on scope and complexity. A simple MVP mobile app typically takes 4–8 weeks, while a full‑featured web application with backend can take 8–16 weeks. I work in iterations with regular demos, so you see progress quickly and can adjust scope as needed.
Do you work with non‑technical founders?
Absolutely. I specialize in translating business ideas into technical solutions. You bring the problem and vision; I handle architecture, implementation, and technical decisions. Regular demos and clear communication ensure you always understand what's being built and why.
What's included in store publishing?
I handle the complete App Store and Google Play submission process: preparing app metadata, screenshots, descriptions, privacy policies, store listings, and managing the review process. You'll need developer accounts (I can guide you through setup), but I handle all technical submission work.
How do you use AI tools? Does it affect code quality?
I use AI tools (like Cursor) to accelerate coding, refactoring, and documentation—similar to how developers use autocomplete or code generators. All architectural decisions, critical logic, and final code quality remain human‑driven. The result is faster delivery without sacrificing senior‑level code quality.
What happens after launch?
After launch, I provide technical documentation, code handover, and a brief maintenance period for bug fixes. Ongoing support, feature additions, and scaling can be arranged separately. I also offer maintenance packages for long‑term support and updates.
Can you work with existing codebases or teams?
Yes. I can take over existing projects, refactor legacy code, integrate with existing systems, or work alongside your team. Whether it's a rebuild, feature addition, or technical consultation, I adapt to your situation.
What's your pricing model?
I work on a project basis with clear scope and fixed pricing, or hourly rates for ongoing work. Each project starts with a discovery call and detailed proposal outlining phases, timelines, and costs. Contact me with your project details for a custom quote.
Who owns the software? Will you sign an NDA?
Upon full payment for the work, you receive full ownership (or an agreed license) of the custom software and deliverables developed for your project. Intellectual property rights in the work product are assigned to you as specified in the project agreement or statement of work. I am willing to sign a Non-Disclosure Agreement (NDA) before engagement to protect your confidential information, business ideas, and proprietary data. Specific terms are set out in the individual contract.
