Design for Mobile App for Heart of Avalon
Myroslav has an excellent team (TechLexity) that was able to work in a focused manner to deliver the Mobile App I had envisioned. The team was excellent with communication, supporting weekly check-ins and making great progress with each Sprint. The final App has a great look and feel and is even better than I had hoped for! Myroslav was very responsive to my business budget needs, as well as delivering the results I required.
I highly recommend Techlexity for their competence and commitment to providing excellent service.

Web Application Developer for Creator Economy
5/5 — Myroslav shipped the community access app incredibly fast without cutting corners. Code quality and integrity were solid throughout, clean architecture that's actually easy to build on top of. Exactly the kind of builder you want when you need speed and substance. Would work with again without hesitation.

About Myroslav
Full Stack Developer React | Fractional CTO | SaaS developer
100%
Job Success
Aventura, United States - 5:43 am local time
10+ Years specifically building SaaS projects. SaaS development from MVP to complex high loaded products.
10+ Projects built with high user load in the role of Full stack developer - Delivered robust applications with a 100% job success score. (As an example app called Niya has over 💲 50.000 💲 active users)
As a Full stack developer - I’m using in frontend (React, Next.js, React Native Tailwind, shadcn and other style UI libraries, Vercel), backend (Node.js, MongoDB, PostgreSQL) Neon, Render, also deep work with supabase (popular for AI Vibe coding). Also as a Full stack developer I made over 15 apps using React Native CLI and React Native Expo, so I’m open to mobile app developer opportunities. I used to work separately as a web developer only as well. As a Fractional CTO I gained a skill to be more specific on the project stack based on project goals, budget and plans.
Performance & Scalability - Being Full stack developer is not only to build and ship it’s also to optimized solutions for speed, SEO, and scalability. I have worked on SEO on domains with high domain authority. Worked a lot with different backend infra providers. Starting some basics, like serverless solutions, finishing AWS services.
Agile Collaboration - Transparent communication, iterative workflows, and timely delivery. I used to be on some projects in the role of project manager as well, I know the right way to manage things. I handle the entire development lifecycle, from React Native UI UX design to backend architecture, API integration, cloud deployment, overall a whole full stack delivery..
Hey, I’m Myroslav, a full stack developer and Fractional CTO on steroids with AI usage and large knowledge as a React developer & Senior web developer & IOS developer & Android developer as well. with over 10 years of experience since 2016, specializing in the Full stack development with different technologies React.js, Node.js, Next.js, Nest.js, React-Native CLI, React-Native, Expo, Vue.js, in generally mostly javascript based. I really love mern and mern stack in general, but nowadays I'm using PostgreSQL for most of the projects.
My focus as a full stack developer is to deliver a fully functional, and production ready MVP for you within 20-40 days, you don’t need to hire ux designer, I’ll handle everything in house. ). I can even handle your "Replit" or "Base44" or "Lovable" or any other AI/Vibe-coding tools you used to make your project. Making sure that we have a great structure & architecture of the application, and making sure it’s ready to get heavy lifting features later on, and supporting hundreds of thousands requests hourly bases. My Fractional CTO experience will bring a new breath to your project.
Industries:
In the past I worked a lot with heavy loaded services that requested difficult mapping, maps, routes integration, orders functionality, complex payment integrations. Also worked many times with Health and Wellness, Transport & Geo, Retail, Dating and Lifestyle, Food Delivery, Fintech and Banking, Entertainment and Media, Logistics and Manufacturing, Productivity and Education, Marketplaces and Advertising, Automotive and Travel.
Frameworks and staff: as a full stack developer, I used a lot of mern and mern stack. I also have experience working as a react developer or web developer only, and full stack developer django in the past. For the last 4 years I've been actively going deep into LLMs and machine learning which is mostly python based, so I’d say I can call myself a senior python developer as well.
