Frequently Asked Questions

Questions about freelance AI development and consultancy in Barcelona and Spain.

Are you available as a freelance AI developer in Barcelona or Spain?

Yes. I am based in Barcelona and available for freelance AI development and consultancy engagements across Spain — including Barcelona, Madrid, and Valencia — and remotely throughout Europe. Typical engagements cover AI product development, automation, RAG systems, and technical project management.

What AI services do you offer?

Six core services: AI product development (scoping and building production-ready AI features), AI strategy and automation for SMEs and SMBs, multi-model AI routing (including AskARC integration), RAG-powered document intelligence systems, technical project management for AI projects, and full-cycle consultancy from initial discovery through to delivery.

How do you help small businesses implement AI?

I run a short discovery session to identify your highest-value automation opportunities, prototype the top use case, and take it to production. Focus is on practical, measurable outcomes — reducing manual overhead, accelerating workflows, or unlocking new capabilities — scoped to match your budget and risk appetite.

How to implement AI automation in my business?

The most reliable path: (1) Audit your current processes for repetitive, rule-based tasks where AI adds clear value. (2) Start with one high-impact use case — typically document processing, customer communication, or internal knowledge retrieval. (3) Build a proof of value with real data before scaling. I guide clients through all three stages and handle the technical build.

What is multi-model AI routing and how does it work?

Multi-model AI routing sends each query to the best AI model for that specific task rather than always using the same model. Simple queries go to smaller, cheaper models; complex reasoning tasks get frontier models. This typically reduces AI API costs by 40–80% with no quality loss. I built AskARC (askarc.app), an OpenAI-compatible gateway that does this automatically.

What is AskARC?

AskARC is an AI API gateway I built at FenxLabs. It is an OpenAI-compatible endpoint that routes queries across 200+ AI models based on complexity, cost, and privacy requirements. It delivers 40–80% AI cost reduction while maintaining EU-sovereign architecture. Operated by FenixMinds B.V. (Amsterdam) under GDPR. See askarc.app.

How do I implement a RAG document intelligence system?

RAG (Retrieval-Augmented Generation) lets your team query a private knowledge base conversationally — like asking a search engine that reads your own documents and returns cited answers. Implementation: (1) Process and chunk your documents. (2) Embed them into a vector database. (3) At query time, retrieve the most relevant chunks and pass them to an LLM. Live demo at hiteshmankani.com/demos/dochat. Built using Azure OpenAI and MongoDB.

What is your approach to AI product development?

I scope MVPs tightly, prototype fast using real data, and prioritise production-readiness from the start — not throwaway demos. Every project includes architecture decisions, privacy-first design (especially for EU clients), and a plan for handover or ongoing maintenance. My background in technical project management means I also manage stakeholder alignment, timelines, and risk alongside the engineering.

What industries do you work with?

I have delivered AI solutions across professional services (coaching, consulting, financial analysis), hospitality (WhatsApp booking and staff management systems), wholesale distribution (ERP systems), and field sales. The underlying patterns — document processing, automation, intelligent routing — apply broadly across industries.

How long does an AI project typically take?

A focused proof of value typically takes 2–4 weeks. A production-ready feature or small product takes 6–12 weeks depending on integrations and compliance requirements. Full AI product builds with multiple modules run 3–6 months.

What AI consulting services are available for small businesses in Barcelona?

For Barcelona-based small businesses, I offer: process audits to identify AI opportunities, affordable phased delivery (pilot first, then scale), Spanish-language support, local in-person workshops, and ongoing retainer arrangements. Engagements start with a free 30-minute discovery call.
