Question 1

Who is behind DexStudio?

Accepted Answer

Robert Sendroiu is a UK-based full-stack developer with 3+ years of experience and 30+ production apps shipped. He builds IT solutions that help businesses overcome daily operational challenges - from managing jobs and bookings to automating data collection and streamlining internal communication. Past projects span automotive, hospitality, vehicle rental, education, and lead generation, and every one has a published case study with real metrics.

Question 2

What industries does DexStudio specialise in?

Accepted Answer

DexStudio works with any business that has a problem technology can solve. Whether you need to replace paper-based processes, automate repetitive tasks, manage bookings, track maintenance, or give your team real-time visibility into operations - the solution follows the same proven patterns: dashboards, real-time sync, role-based access, and offline-capable apps. Past clients include garages (GaragePRO), hotels (PremierFix), vehicle rental agencies (SmartRent), and lead generation teams (ScraperBot), but the approach applies to any industry. If your business has a daily pain point that software can fix, DexStudio can build the solution.

Question 3

Are you available for projects outside the UK?

Accepted Answer

Yes. DexStudio works with clients worldwide. Communication happens via Slack, email, and weekly Microsoft Teams video demos regardless of timezone. GaragePRO was built for a garage in France entirely remotely, and the same process works for any business anywhere.

Question 4

What makes DexStudio different from other freelancers?

Accepted Answer

Every project has a published case study with real metrics - 65% admin time reduction (GaragePRO), 42% higher booking conversion (SmartRent), 5,000+ businesses scraped in under 30 minutes (ScraperBot), 80% faster issue resolution across 8 hotels (PremierFix). These results come from solving real business problems, not just writing code. Transparent fixed pricing, weekly video demos, and formal contracts eliminate the uncertainty common in freelance engagements.

Question 5

How long does it take to build a booking system?

Accepted Answer

A production booking system with multi-step flow, availability checking, and payment integration takes 4–6 weeks. SmartRent's booking system was delivered in 5 weeks and increased conversion by 42%. The same approach works for any business that takes appointments, reservations, or scheduled services.

Question 6

How long does it take to build an MVP?

Accepted Answer

A Starter MVP with 5 core pages, authentication, database, and deployment takes 2–4 weeks. The timeline depends on feature complexity - a simple landing page is 2 weeks, while an app with real-time features is closer to 4. This applies to any business idea, not just specific industries.

Question 7

What is your development process?

Accepted Answer

Four steps: (1) Free 30-minute discovery call to understand your business problem, (2) fixed-price proposal delivered within 48 hours, (3) weekly Microsoft Teams video demos during the build so you see real progress, (4) launch with 14–30 days of free post-launch support. Formal contracts and milestone-based payments (40/30/30) on every engagement.

Question 8

Do you offer post-launch maintenance?

Accepted Answer

All projects include 14–30 days of post-launch support. After that, maintenance retainers or pay-per-change arrangements are available. Most small changes are turned around within 24–48 hours. This keeps your app running smoothly as your business grows.

Question 9

Can you build a real-time web app with Firebase?

Accepted Answer

Yes. GaragePRO uses Firestore real-time listeners for instant job updates and chat with auto-translation across 5 languages. Firebase handles scaling automatically - GaragePRO processes 200+ real-time messages daily with sub-second delivery. Whether your business needs live order tracking, team messaging, or real-time dashboards, the same architecture applies.

Question 10

Can you build an offline-first PWA for my business?

Accepted Answer

Yes. Both GaragePRO and PontajPRO are installable PWAs with offline support via Firestore persistent cache and service workers. Users can log data without internet, and it syncs automatically when connectivity returns. This is ideal for any business where staff work in areas with poor signal - warehouses, basements, rural sites, or on the road.

Question 11

What technologies do you use?

Accepted Answer

Core stack: React/Next.js + TypeScript + Firebase for web apps, Python for automation and AI. Tailwind CSS for styling, Framer Motion and GSAP for animations. The specific tools are chosen per project - not a one-size-fits-all approach. 28+ technologies across frontend, backend, databases, and DevOps, picked to match what your business actually needs.

Question 12

Can you build a web scraper or data extraction tool?

Accepted Answer

Yes. ScraperBot extracts 5,000+ businesses from Google Maps in under 30 minutes using Playwright with anti-detection, parallel processing, and a deep email extraction pipeline. Custom scrapers and automation tools start from £400 and can be tailored to any data source or workflow your business relies on.

Question 13

Do you build custom business management software?

Accepted Answer

Yes. GaragePRO is a great example - a full-featured management platform with job tracking, real-time messaging with auto-translation, quotes and invoicing, parts inventory, and multi-role dashboards. It reduced admin time by 65% for a garage in France. The same approach works for any service-based business that needs to track jobs, manage teams, handle invoicing, or streamline daily operations.

Question 14

How much does a custom web application cost?

Accepted Answer

Most business apps fit within our three service tiers: Starter MVPs from £1,000 (2–4 weeks), full custom applications from £2,000–£6,000 (4–10 weeks), and AI or automation add-ons from £400–£2,000. That said, every business is different. If your project doesn't fit neatly into those tiers, we can discuss a tailored scope and price. The majority of business IT solutions fall within these ranges, but nothing is off the table - book a free discovery call and we'll work out what makes sense for your situation.

Question 15

How do payments work?

Accepted Answer

40% upfront deposit, 30% at midpoint milestone, 30% on delivery. Formal contracts are used for every engagement. For larger projects, milestone-based payment schedules are arranged to match development phases. This structure keeps both sides aligned and ensures you only pay as real progress is delivered.

Question 16

Can you take over and improve an existing codebase?

Accepted Answer

Yes. Robert has taken over several existing projects across different industries. The process starts with a thorough code audit and a clear improvement plan with priorities before any development begins. This ensures you know exactly what you're paying for before work starts, regardless of the technology or business domain.
