You need software that solves a real problem, built right the first time, by people who understand your business and not just your stack.
I'm Orest, founder of SoftDoes. We're a U.S.-based custom software firm working with:
• Non-technical founders with a vision
• Technical leaders who need help but not additional headcount
• Business operators solving operational complexity
Our team has delivered across healthcare, fintech, construction, legal, real estate, and regulated industries where compliance-readiness is required and getting it wrong isn't an option.
Our clients tend to show up in one of three situations: they have a product vision and need someone to build it, they have internal engineering that's stretched too thin, or they have operational complexity that off-the-shelf software simply can't fix. We've handled all three.
What we deliver:
• Custom software and SaaS platforms built for scale
• AI implementation and automation built into real workflows
• Web and mobile applications
• Cloud infrastructure on AWS, GCP, and Azure
• Full-stack development across React, Next.js, Node.js, and Python
What clients tell us, consistently: we listened, we delivered what we said we would, and they didn't have to babysit us to get there. A healthcare founder went from concept to a live, compliant product in under six weeks. A construction company replaced five fragmented tools with one custom operations platform. A fintech team cut onboarding time in half with an AI-assisted workflow we built in a single sprint.
We work best with companies that are big enough to need real software and clear-eyed enough to know that building it wrong the first time costs more than doing it right.
If that's where you are, let's talk.

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.

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.

Top 1% on Upwork, Fractional CTO helping startups build scalable applications. 100+ products delivered | Companies we supported raised $14.5B+. Expert in React, Node.js, .NET, Python, API integrations, AI automation, and SaaS architecture.
As a Fractional CTO and Solution Architect, I typically join projects when companies need to:
• launch an MVP quickly
• fix slow or disorganized development
• design scalable product architecture
• integrate APIs, automation, or AI features
I work together with my team at Softermii, where we have delivered 100+ Web and Mobile products, helping companies that later raised $14.5B+ in funding.
APEX – AI-Powered Product & Engineering System
To reduce delivery risk and accelerate development, we use our internal framework APEX.
APEX helps us validate product scope, architecture, timelines, and technical risks before heavy development begins.
This allows us to:
• structure the development roadmap
• break features into clear engineering tasks
• accelerate MVP delivery
• reduce costly rework
The result is faster product launches and more predictable development timelines.
