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.

I’m a Senior Java Backend Engineer with over 14 years of experience building mission-critical systems in fintech, with a strong focus on payments, lending platforms, and core banking solutions. I specialize in Java and Spring Boot, and design backend systems that are secure, scalable, and capable of handling high-volume financial transactions with consistency and reliability. I’ve worked on systems involving payment processing, transaction workflows, loan management, and integrations with external financial services and APIs. This includes designing and building robust microservices architectures that support real-time and asynchronous processing, ensuring data accuracy, fault tolerance, and seamless service communication. I understand the importance of idempotency, transaction integrity, and failure handling in financial systems where even minor inconsistencies can have significant impact. Security and compliance are central to my approach. I have strong experience implementing secure authentication and authorization using Spring Security, token-based systems, and role-based access control. I build APIs and backend services that align with financial industry expectations around data protection, auditability, and reliability. From a technical standpoint, I bring deep expertise in Spring Boot, microservices, REST API design, JPA/Hibernate, and relational databases like MySQL and PostgreSQL. I’m comfortable designing systems from scratch as well as improving and scaling existing platforms, optimizing performance, and ensuring stability under load. I also have hands-on experience with AWS and Google Cloud, and have worked on deploying and managing backend systems in cloud environments. I understand how to design cloud-ready architectures, implement CI/CD pipelines, and ensure systems are resilient, observable, and production-ready. What sets me apart is my ability to think beyond just implementation. In fintech systems, correctness, reliability, and long-term maintainability matter more than quick fixes. I focus on building clean, well-structured systems that not only meet current requirements but are also prepared for future scale, regulatory needs, and product evolution. If you’re building or scaling a payments platform, lending system, or core banking backend and need someone who understands both the technical and domain challenges, I’d be glad to contribute.
