Project details
You've got the idea. Now you need something real to put in front of customers.
This takes you from product clarity to a clickable, testable prototype in 5 days — without hiring a dev team or burning through your runway. We start with a focused 2-hour strategy session to lock in your core hypothesis and define exactly what to build. Not everything. The right thing.
From there, we write a clean requirements doc and build a working prototype using Lovable or Replit — functional enough to validate with real users, fast enough to not slow you down.
No bloated sprints. No 3-week discovery phases. No agency overhead.
This is for founders who are past the "should I build this" stage and ready to answer: "will people actually use it?" — with evidence, not assumptions.
The output isn't just a prototype. It's a validation-ready artifact with a defined hypothesis you can test immediately.

Full-stack developer for B2B SaaS (experiences with Large Systems)
Working with Volodymyr on our B2B SaaS product was exactly what we needed at a critical stage. We weren’t looking for someone to just ship an MVP fast. We needed a SaaS developer who understood how real SaaS products are structured and why early architectural decisions matter a lot down the road.
The SaaS development process was well-structured from day one. Volodymyr asked the right questions, flagged potential issues for MVP before they became problems, and helped us build foundation we’re actually confident scaling. Beyond just executing the task, he proactively recommended next steps, including AI features and third-party integrations that would add real value as the product grows.
Great experience working with a developer who thinks beyond the current sprint. Would absolutely work together again on future SaaS projects.

PropTech MVP Development - Real Estate Platform / Tenant Portal
Great experience working with Volodymyr. We had a very productive consultation phase that helped lay a solid foundation for our B2B platform. He demonstrated strong experience in SaaS development and approached the project with a clear understanding of MVP strategy and delivery.
As a skilled full stack developer, Volodymyr showcased deep technical expertise in Django and React, along with strong experience in building complex end-to-end platforms, which was exactly what we needed. Because of this, he asked the right questions, quickly aligned on the technical approach, and provided thoughtful recommendations throughout the process.
He also delivered clear, well-structured materials that made planning the next development steps straightforward. I’d be happy to continue into the next phase with him and would gladly work together again in the future.

As a CTO with 15 years of experience, I've learned that most founders don't fail because they can't build — they fail because they build the wrong thing. My job is to make sure that doesn't happen to you.
I'm Founder and CTO of Gearheart and Co-Founder and CTO of Beyond the Wow. As an AI-native MVP developer team, we combine product strategy with AI-powered SaaS development to help founders go from idea to revenue-ready product in weeks, not months. I help you figure out what's worth building first, and then we move fast.
Our SaaS development standard comes from 14 years of enterprise product work at Gearheart, where every Full Stack developer on our team has built production-grade systems at scale:
SmartSuite — a B2B SaaS development project built from scratch. Reached $1.2M ARR in 4 weeks post-launch, raised $38M, trusted by Capital One.
Globalli — an HR SaaS platform powering payroll across 125+ countries, raised $15M+, SOC2 Type II certified.
WHAT I CAN HELP YOU WITH
Discovery & Prototype
For founders with product clarity, I turn your knowledge into a clickable prototype in 5 days, ready to validate with real customers. Core hypothesis and scope definition, requirements doc for MVP development, clickable prototype built with Lovable or Replit.
Rescue Diagnosis
Built something on Lovable, Replit, or Base44 but it's breaking in production? I audit the technical and product gaps and give you a clear path forward. Full code review by a senior Full Stack developer, QA and security audit, product gap analysis, sprint plan and cost estimate for the fix.
MVP Development & Landing Page
Validated idea, early customers, ready to invest? I deliver a production-ready MVP with landing page in 3–4 weeks. One core use case, built right. AI-assisted SaaS development (Claude Code, Lovable), database and API integrations, user authentication and onboarding flow, product design components, production-ready deployment.
Sprint Subscription
Ongoing SaaS development support — ship new features and product improvements at a regular sprint pace, with Full Stack developer quality maintained throughout.
Our team is made up of senior Full Stack developers who have spent years building enterprise-grade SaaS products. You get MVP development speed without giving up the engineering quality that only comes from people who have built at scale.
SaaS DEVELOPMENT SPEED
Legal document analysis SaaS platform with AI chatbot — built in ~2 months.
AI Receptionist for SMBs with CRM integration — MVP development completed in weeks.
Referral System for Dental Clinics, B2B SaaS referral automation — MVP shipped in 3 weeks.
Medical device industry SaaS platform — ICP defined, PMF validated, MVP shipped in 2 weeks.
WHY WORK WITH ME
Product Thinking First: We start at "should you build this?" not "what do you want us to build?" Most SaaS developers skip this question entirely. We don't.
AI Speed, Engineering Quality: We use Claude Code, Lovable, and Cursor as real engineers, not prompt writers. SaaS development delivery is 2–4x faster without sacrificing production readiness. Need an AI MVP or a full SaaS development project? We do both.
We're Startup Founders Too: As founders ourselves, we understand the pressures you're facing and work as partners, not vendors.
Offshore Pricing, Enterprise Standard: Ukraine-based Full Stack developer team. Competitive rates. Enterprise-level quality on every MVP development and SaaS development project.
