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).

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.

AI Engineer specializing in production-ready AI Agents, advanced RAG systems, and enterprise LLM integrations. Over 17,000 hours tracked delivering scalable, hallucination-free AI architectures for business platforms. Companies often discover that AI prototypes work well in demos but fail when integrated into real production workflows. I close that gap by building secure, production-grade systems designed to automate legacy processes and leverage corporate data assets smoothly without disrupting your existing infrastructure. Where I Help ============ ♦ Designing Autonomous AI Assistants & Copilots: Securely connected to internal documents, enterprise databases, and operational tools for grounded, reliable responses. ♦ Multi-Agent Workflow Systems: Building resilient AI agent squads capable of executing complex business logic via APIs using frameworks like LangGraph and CrewAI. ♦ Advanced Retrieval-Augmented Generation (RAG): Combining enterprise data with LLMs using robust vector databases for context-aware, hyper-accurate outputs. ♦ Generative AI SaaS Integration: Embedding generative capabilities seamlessly into existing SaaS platforms and enterprise applications while maintaining architectural stability. ♦ Multimodal AI Solutions: Developing applications where text, images, and audio inputs operate smoothly within unified production environments. ♦ Data Ingestion & Knowledge Pipelines: Structuring scattered information into high-performance, searchable intelligence layers. How I Work ========== ⚙️ Production-First Architecture: Prioritizing scalability, strict security, and cost-efficiency instead of short-term experimentation. ⚙️ Guardrails, Evaluation & Monitoring: Implementing evaluation frameworks to ensure LLM behavior remains deterministic and predictable after deployment. ⚙️ Advanced Prompt & Context Engineering: Designing context windows and prompt techniques to improve response reliability and reduce latency. ⚙️ Model Selection & Fine-Tuning Strategies: Balancing open-source (Llama 3) and proprietary models (GPT-4o, Claude 3.5) to optimize performance and operational cost. ⚙️ Cross-Functional Collaboration: Aligning closely with product and engineering teams to ensure deployments remain highly extensible. Solutions Delivered ================ 🧩 Enterprise Knowledge Assistants for real-time conversational access to internal data. 🧩 Workflow Automation Agents executing complex, multi-step actions across integrated business apps. 🧩 Custom AI Copilots seamlessly embedded directly into SaaS platforms. 🧩 Intelligent Document Processing (IDP) and contextual search systems. 🧩 AI Integration Layers connecting LLM capabilities smoothly with legacy software. Tech Expertise ============= 🚀 Languages & Frameworks: Python (FastAPI), Node.js, LangChain, LangGraph, CrewAI, LlamaIndex. 🧠 AI & LLM Ecosystem: OpenAI APIs (GPT-4o), Anthropic Claude, Open-Source LLMs (Llama 3). 🗄️ Vector Databases & Infrastructure: Pinecone, ChromaDB, Weaviate, PostgreSQL (pgvector). ☁️ Cloud & DevOps: Docker, AWS, Google Cloud Platform (GCP) cloud-native deployments. 📊 MLOps & Observability: Weights & Biases, Arize Phoenix, or custom telemetry tooling for tracking model drift and latency. Working Style ============= 🤝 Structured planning before development reduces ambiguity. 🤝 Incremental delivery enables early validation and predictable progress. 🤝 Clear, proactive communication across technical and business stakeholders. 🤝 Systems designed for long-term maintainability and easy handover to internal teams. AI delivers lasting enterprise value when integrated naturally into workflows and supported by robust engineering foundations. Let's build a solution tailored to your operational goals.
