Startups, enterprises and public-sector organizations bring me in when the product needs strong technical decisions, not just execution - production AI systems, SaaS platforms and fintech, from architecture to live deployment. Most engagements start with a fixed-price design phase that defines architecture, scope and roadmap, then convert into fixed milestones, so delivery stays structured and budget predictable. Rate $125-150/hr depending on complexity; most work is delivered as fixed-price milestones. What I specialise in: AI/LLM systems - RAG pipelines, multi-tenant AI assistants, agent orchestration, Claude/OpenAI integrations, structured outputs, eval pipelines. SaaS platforms - multi-tenant architecture, subscription billing, RBAC, admin backends, scalable APIs across web and mobile. Fintech/compliance - ACH, Stripe Connect, idempotent payment webhooks, audit logging, GDPR-compliant data. Govtech/regulated - transparency platforms, donor-funded compliance, multi-language reporting. Blockchain/Web3 - Solana smart contracts, SPL tokens, DeFi integrations. Selected results (live demos and links in the Portfolio section): Minerva (active production) - multi-tenant AI assistant platform architected end to end: organizations upload document libraries and deploy embeddable chatbots on their own knowledge base. Hybrid retrieval (BM25 + dense vector + semantic), Entra ID + RBAC + MFA, full tenant isolation, golden-query eval harness in CI. NestJS, Next.js, Azure OpenAI. Diginak.ai (active production, lead architect) - logistics document automation that auto-processes ~78% of inbound PDF/CSV/Excel with zero human touch; the remainder routes to human review with confidence scores. Claude API + tool use, state-machine workflow engine, retry/idempotency, 850+ automated tests. NestJS, PostgreSQL. Walletta AI Cashier (concluded May 2026, 5-star) - real-time voice agent with sub-500ms perceived latency. Claude + GPT-4o orchestration, structured tool calls with confidence-scored routing, persistent WebSocket, retry with circuit breaker. LiveKit, Deepgram, ElevenLabs, NestJS. Damen Capital Portal (concluded May 2026, 5-star) - loan-servicing portal for a private lender with the full ACH lifecycle: tokenization, NACHA returns R01-R85, HMAC-verified idempotent webhooks, append-only audit log, OAuth 2.0 + RBAC, scheduled reconciliation. NestJS + Fastify, Supabase. PulseYourBiz (active production) - all-in-one SaaS for service providers: bookings, payments, invoicing, CRM, analytics. Five-app Turborepo monorepo, Stripe Connect payouts, idempotent webhooks, React Native mobile. Docker + GitHub Actions. ProveYourImpact (production) - multi-tenant governance/compliance platform for donor-funded projects in PALOP countries: 20 API modules, 9-role RBAC, configurable workflow engine, audit log, EU/UNDP/World Bank report generators in four languages. NestJS, Next.js, PostgreSQL + RLS. Also shipped: no-code Solana token/DeFi platform with 1,500+ users (SwapForge), offline-first clinical decision support for underserved regions (ExtendYourClinic), multi-tenant VetSaaS with PostgreSQL RLS isolation (acti.vet), React Native apps live on both app stores (ForroAI). Tech stack: Backend: Node.js, NestJS, Python, FastAPI, REST, GraphQL. Frontend: React, Next.js, React Native, Expo, TypeScript, Tailwind. AI: Claude, OpenAI, RAG, pgvector, Azure Cognitive Search, structured outputs (Zod/Pydantic), prompt caching, tool use, eval harnesses in CI. Cloud: Azure (Functions, OpenAI, Entra ID, Key Vault, App Insights, Bicep IaC), AWS, GCP, Docker, GitHub Actions. Databases: PostgreSQL, MongoDB, Redis, Supabase, RLS tenant isolation. Blockchain: Solana, Anchor, SPL, Jupiter, Solidity, EVM. Working model: 25-30 hrs/week across a small number of parallel engagements. Best fit when the product needs architectural ownership - not a fit for quick fixes or one-off tasks.

I am a Hungarian-born astronomer and scientific researcher currently residing in the Kansai region of Japan. I hold a Master of Science in Astronomy and a Bachelor of Science in Earth Sciences from Eötvös Loránd University. My professional background bridges the gap between rigorous scientific research, advanced data analysis, and cross-cultural communication. Since 2019, I have operated as a freelance English-to-Hungarian translator, managing localisation projects for mobile games, webshop content, technical articles, and corporate services. Having successfully completed long-term glossary and gameplay string translations for mobile game developers, I know how to restructure literal text to ensure culturally accurate and natural phrasing. Beyond my native Hungarian and professional working English (TOEFL iBT score: 101), I have daily conversation-level Japanese and intermediate German, allowing me to navigate multicultural environments and complex localisation projects with ease. In addition to my linguistic work, I am deeply involved in data analysis and technical programming. I hold professional Data Analyst certifications from both IBM and Google, backed by strong skills in database management and SQL. I am highly proficient in Python and Jupyter, frequently utilizing tools like Pandas and BeautifulSoup for data visualization and web scraping. My academic background also gave me hands-on experience using C and IDL to solve complex physical problems. For documentation, I regularly use the full Microsoft Office suite and rely exclusively on LaTeX to produce fast, flawlessly formatted academic papers and scientific texts. Currently, I serve as a Researcher at Agromaton Systems LtD, where I conduct in-depth analysis on GNSS signal vulnerabilities and mitigation strategies. I am highly experienced in preparing comprehensive technical documentation covering satellite constellations, spoofing threats, and defense applications. Whether I am analyzing complex data sets or translating technical concepts into clear, accessible material, I leverage my analytical mindset and rigorous attention to detail to deliver high-quality, professional results for my clients.
