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.

Most backend systems don't fail because of bad developers. They fail because no one took real ownership, of performance, of scalability, of the decisions that matter when traffic spikes or a payment gateway breaks. That's the gap I fill. I'm a Senior Java Spring Boot Engineer with 9+ years of experience building backend systems for fintech platforms, high-compliance environments, and cloud-native microservices. I take full ownership from development to production — not just the next ticket on the board. 🏆 Top Rated Plus — Top 3% of developers on Upwork 💼 9+ years building scalable backend & cloud-native systems 📦 7000+ Upwork hours with consistent 5★ feedback 💰 20+ enterprise-grade platforms delivered globally 🌍 Available across EST, CET, and PKT timezones ⚙️ 𝐖𝐡𝐚𝐭 𝐈 𝐁𝐮𝐢𝐥𝐝 Backend & Microservices: Java 8–21, Spring Boot 3, Spring Security, Hibernate/JPA, REST/gRPC, Kafka, Event-Driven Architecture Cloud & DevOps: AWS (Lambda, ECS, S3, Aurora), Docker, Kubernetes (EKS), CI/CD (GitHub Actions, CodePipeline) Data & Messaging: PostgreSQL, MySQL, MongoDB, Redis, Kafka Streams Security & Testing: OWASP Top 10, RBAC, JWT/OAuth2, JUnit, Mockito, Testcontainers Frontend & Integration: React, TypeScript, Third-party APIs, Payment Gateways AI-Accelerated Development: GitHub Copilot, Cursor, Bolt.new — faster delivery, smarter workflows, automated testing ⭐ 𝐏𝐫𝐨𝐣𝐞𝐜𝐭𝐬 𝐓𝐡𝐚𝐭 𝐒𝐩𝐞𝐚𝐤 𝐟𝐨𝐫 𝐓𝐡𝐞𝐦𝐬𝐞𝐥𝐯𝐞𝐬 𝗚𝗹𝗼𝗯𝗮𝗹 𝗙𝗶𝗻𝗮𝗻𝗰𝗶𝗮𝗹 𝗠𝗲𝗱𝗶𝗮 — Rebuilt and deployed on AWS S3 + CloudFront.

🔥 Send me your idea — and I’ll give you a free initial consultation with practical thoughts, possible solutions, and a rough time and cost estimate. Legacy systems draining budget, slowing delivery, and blocking growth? At OSKI Solutions, we help companies modernize legacy applications and build scalable cloud-ready products with our 3x delivery strategy: experienced engineers + AI-assisted coding + disciplined execution. That means you get more than just developers. You get a team that can move significantly faster on implementation, reduce repetitive work through AI-assisted workflows, and still keep architecture, maintainability, and business priorities under control. Most of our engineers are from Ukraine, and we’ve built a delivery model that combines strong technical talent with modern AI tools to help clients ship faster without sacrificing code quality. Over the past 20+ years, I’ve worked as a senior engineer, architect, and ex-CTO, helping startups, SMBs, and enterprise clients rebuild outdated systems into secure, scalable, future-ready platforms. We work hands-on with .NET, Node.js, React, and modern cloud infrastructure to turn brittle systems into products that are easier to maintain, extend, and grow. What we do best Backend Development .NET Core, ASP.NET MVC, C#, Entity Framework Node.js, Express, REST APIs, GraphQL APIs Microservices, event-driven systems, business-critical backend logic Frontend Development React, Next.js, TypeScript, Redux Angular, Vue.js, SPA and PWA development Responsive interfaces, Tailwind, Material UI Legacy Modernization Legacy .NET and custom business platform modernization Monolith to modular/cloud migration Performance, maintainability, and technical debt reduction CMS & Business Platforms Umbraco CMS, Umbraco Cloud, migrations, custom development ERP-related systems and workflow platforms Internal tools, client portals, dashboards, admin systems Cloud & DevOps Azure, AWS, Google Cloud Docker, Kubernetes, CI/CD pipelines GitHub Actions, GitLab CI, deployment automation Databases SQL Server, PostgreSQL, MySQL MongoDB, Redis, caching and query optimization API Integrations & SaaS Stripe, PayPal, Twilio, SendGrid Slack, Shopify, Zoom, QuickBooks, Google Maps SaaS integrations, workflow automation, external service connectivity Why clients choose OSKI Solutions 3x delivery strategy: senior engineers + AI-assisted coding + structured execution 20+ years of experience modernizing complex systems CTO-level thinking focused on business outcomes, not just tickets Full-cycle delivery from architecture to deployment Lean, practical approach that keeps MVPs and modernization efforts within scope Clear communication with weekly demos, tracked hours, and transparent reporting Selected results One Motion Technologies — designed and built ERP system from scratch TutorPro — helped scale a SaaS platform, supporting 3x adoption growth in 2 years Umbraco platforms — delivered 15+ CMS and business platforms, including cloud migrations and integrations What our 3x approach means in practice We use AI to accelerate coding, prototyping, refactoring, and repetitive engineering tasks — but not to replace engineering judgment.
