I’m a Software Engineer and SaaS/AI product builder focused on MVP development, full-stack development, web apps, mobile apps, automation-heavy platforms, CRMs, admin dashboards, client portals, marketplaces, and AI-powered tools.
I use a practical engineering stack to build fast and scalable products: Next.js, React, React Native, Expo, Supabase, PostgreSQL, Node.js, SQL, JavaScript, APIs, Stripe, OpenAI/Claude, Claude Code, Cursor, and AI-assisted development workflows.
Clients usually come to me when they need one of three things:
→ A SaaS MVP or startup MVP built from scratch and launched quickly
→ A web or mobile app with clean architecture, authentication, database design, payments, and admin logic
→ An AI agent, LLM application, chatbot, RAG system, automation system, or internal tool connected to real business workflows
What I can help with:
→ SaaS MVP architecture and product development
→ Full-stack web development with Next.js, React, Supabase, PostgreSQL, Node.js, and APIs
→ React Native / Expo mobile app development
→ Supabase backend, auth, database, storage, RLS, and SQL
→ AI agents, LLM apps, OpenAI/Claude integrations, GPT-based chat, AI chatbots, summarization, RAG, and workflow automation
→ Stripe subscriptions, payments, Apple Pay / Google Pay
→ API integration, custom JavaScript/Node.js logic, and backend automation
→ CRM systems, client portals, marketplaces, admin dashboards, internal tools, and operational dashboards
→ QA, launch support, performance improvements, and post-launch iterations
Beyond client work, I research explainable AI as a PhD student and teach AI agents, automation workflows, and practical AI product development. This helps me design AI systems that are not just impressive in a demo, but structured, understandable, and useful in real business operations.
My approach is simple: clarify the business goal, design the right data structure and workflows, build fast, test end-to-end, and make sure the product is actually usable by real users.
You work directly with me as the technical lead. If the project needs more capacity, I can also involve trusted specialists for design, QA, automation, or additional development.

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.
