ABOUT ME A full-stack Java developer with a passion for creating efficient and user-friendly applications. Proficient in utilizing open-source technologies to develop and implement scalable solutions. Proven ability to turn complex problems into simple and elegant solutions. Committed to staying up-to-date with the latest industry developments and constantly seeking new challenges to grow as a professional.

I'm a senior software engineer and architect with 20+ years of experience — deep in Java, and equally productive in Python and JavaScript/TypeScript, using the latest tooling and AI across all of them. For a decade I was a core architect and lead contributor of the open-source Swagger/OpenAPI Java tooling - including e.g. Swagger Core with 30M+ monthly downloads on Sonatype - that thousands of companies build on. I played a key role in the growth of Swagger/OpenAPI-based commercial platforms, driving architecture and implementation for code generation, SCM and cloud integrations, parsing, validation and plugin frameworks — from concept to profitable SaaS offerings. I now build API tooling for the AI-agent era. For a sample of my work, see GitHub: frantuma What I can do for you: • API design & OpenAPI/Swagger, across environments — design, review, and fix OpenAPI, AsyncAPI, Arazzo, and JSON Schema specs, in Java, Python, or JS/TS; build API-first workflows; resolve the spec problems that break your integrations and SDKs. • Multi-language engineering — high-performance backends, library design, and tricky migrations in Java (I led a full Jakarta EE migration and the OpenAPI 3.1 rollout for widely-used libraries), Python, and TypeScript. • AI + APIs — make your APIs "AI-ready" so agents can call them reliably; build agent skills, LLM integrations (Claude, OpenAI, Gemini, Bedrock), and spec-driven, agentic development workflows. • Rescue an AI-augmented project that's drifting — when an AI-assisted or agent-driven build has lost coherence, accumulated churn, or gone off-track, I bring the senior judgment and structure to get it back under control. • Code evaluation, assessment & refactoring — review and improve Java, Python, and JS/TS codebases: architecture assessment, refactoring, quality and maintainability. • Developer tooling — parsers, validators, linters, language servers, code generation, CLIs. I work spec-first: we agree on the specification, then implement and verify against it. That discipline is what keeps integrations predictable and is exactly what makes AI-assisted development dependable rather than chaotic. Recent proof: primary engineer of an OpenAPI "AI-readiness" platform that scores and improves API specs for AI agents; ideator/architect of the open-source jentic-openapi-tools toolkit; co-creator of an open-source OpenAPI scoring CLI; co-founder of SpecLynx, whose OpenAPI tooling is published and in use. Whether it's a clean API contract, a stubborn migration, an AI integration that needs to actually hold up, or a drifting AI project that needs to get back on track — I'm happy to take a look and give you a straight answer on whether and how I can help.

I have been working in software development for over 10 years and in project management for 5+, combining strong technical expertise with the ability to guide projects from concept to successful delivery. My background allows me to move easily between writing clean, scalable code and coordinating teams to achieve ambitious goals. On the technical side, my main stack includes, but is not limited to: * Laravel (7+ years) * Vue.js, React, and React Native (6+ years) * Node.js (~2 years) * Experience with Flutter for mobile applications This diverse toolkit lets me adapt to different project needs, from robust APIs to intuitive user interfaces and mobile apps. On the project management side, I help both startups and established companies shape their technological vision and turn it into reality. I have experience managing projects of various sizes, from small MVPs to larger, more complex systems up to the corporate level. I handle every stage of the process - from planning and resource allocation to execution and delivery - ensuring that business objectives and technical requirements stay aligned. What drives me is the challenge of building high-quality, scalable products while fostering collaboration between clients, developers, and stakeholders. I enjoy translating ideas into solutions that don’t just work today, but are designed to grow and evolve over time.
