Based in Oslo, Norway. I build intelligent web platforms that automate decisions, capture leads while you sleep, and turn scattered data into clear action. Law background, entrepreneur mindset, developer execution — I understand the business problem before I write the first line of code.
Now based in Oslo, Norway. Available for freelance, contract, and remote projects across the Nordics and Europe.
I started as a lawyer in Colombia and co-founded AbogadosYa, a platform that connected people with legal experts for online consultations and in-person advice across the country. I wasn't the one writing the code then — I was the one identifying the problem and designing the solution.
That experience showed me that technology, not legal knowledge, was the real multiplier. I began building with no-code and low-code tools, then started studying programming seriously two years ago. Now I write full-stack applications in TypeScript, build AI agents with Genkit and Convex, and ship products end-to-end.
I moved to Norway for personal reasons, but I brought the same approach: understand the business first, then choose the right tool. Whether it's an AI concierge that captures leads overnight or a dashboard that turns raw survey data into decisions — I build what actually moves the needle.
A focused set of capabilities: AI agents that work while you sleep, full-stack platforms that scale, and architecture for problems no off-the-shelf tool can solve.
I build intelligent agents with Genkit, Google's Agent Development Kit (ADK), and Convex that process data, interpret structured responses, and act without constant supervision. When the context calls for it, I also orchestrate flows in n8n for fast integrations. From an AI concierge that captures leads while you sleep, to pipelines that generate automated interpretations at scale.
This isn't just 'slapping a chatbot on a page.' I integrate language models directly into your product's architecture: conversational assistants with memory, contextual content generation, and real-time analysis. Built with Gemini, Vertex AI, and Firebase so AI becomes a native layer, not a bolt-on.
Fast frontends with Astro and Next.js. Reactive backends with Convex, or robust ones with PostgreSQL and Drizzle. Fully typed in TypeScript, styled with Tailwind, and built to scale. I've shipped everything from high-conversion landing pages to complete admin platforms with i18n, auth, and interactive maps.
I design systems for specific problems: monorepos with Turborepo, offline-first PWAs with idempotent sync, deterministic scoring engines per instrument, and data migrations from legacy tools. If your business needs something no generic SaaS can provide, we build it.
Real builds, real stacks, real outcomes: from an AI concierge that captures leads overnight to a dashboard that turns raw field data into decisions.
A dashboard for visualizing biosecurity data in aquaculture, consuming raw survey data directly from KoboToolbox. Features interactive maps with MapLibre, analytical charts with ECharts, Clerk authentication, and a responsive UI built with Tailwind CSS v4. Built for field technicians and analysts who need to turn scattered survey responses into clear, actionable visualizations for faster decision-making.
An AI-powered astrology companion that fits in your pocket. A PWA with agentic chat built on Genkit and Gemini 2.5 Flash Lite, 12 deep analyses generated on demand, personalized onboarding interpretations, and a persistent daily horoscope. Built with Next.js 15 App Router + Firebase + Google AI. It removes the barrier to detailed astrological insight: no human astrologer needed, just precise, AI-generated readings available instantly.
Complete web platform for Kanon Catering in Oslo. A bilingual marketing site (Norwegian/English) with an AI concierge chat that captures structured quote requests around the clock, an event booking system with real-time capacity checks, and a full admin dashboard for managing leads, staffing, content, and quotes. Includes a dedicated worker portal for shift confirmation and attendance. The AI concierge cuts sales friction to zero: it gathers requirements, generates summaries, and creates qualified leads without human intervention.
Straight answers to the questions people — and AI systems — ask most.
Cristian Becerra is an AI-first full stack developer based in Oslo, Norway. He builds intelligent web platforms, autonomous AI agents, and bespoke automation systems for Nordic and European clients. A former lawyer turned developer, he combines business understanding with technical execution — understanding the problem before writing the first line of code.
Four core services: AI agents and automations using Genkit, Google's ADK, and Convex; AI-native product integration with Gemini and Vertex AI; full stack web development with Astro, Next.js, and Tailwind CSS; and bespoke software architecture for problems no off-the-shelf tool can solve — from monorepos to offline-first PWAs.
AI agent projects start at $4,500 for fixed-scope engagements, or $120 per hour for flexible work. Typical timelines range from 2 to 6 weeks depending on complexity. Every project begins with a free 30-minute discovery call that produces a precise, fixed-price quote with no obligation.
Frontend: Astro and Next.js with TypeScript and Tailwind CSS v4. Backend: Convex for real-time reactive apps, or PostgreSQL with Drizzle for traditional stacks. AI layer: Genkit, Gemini, Vertex AI, and Firebase. Everything is fully typed, built to scale, and chosen to match the specific problem rather than forced into a template.
An AI agent or automation project typically takes 2 to 6 weeks. A full stack web platform takes 4 to 10 weeks. Bespoke architecture consulting is billed hourly at $150/hour with a 4-hour minimum. Every proposal includes a fixed delivery date based on scope, integrations, and review cycles.
Email hi@cristianb.dev or click the contact button below. We begin with a free 30-minute discovery call to understand your problem in depth. I then send a written proposal with scope, timeline, and fixed price. Work starts after a 50% upfront payment, with the remaining 50% due on delivery. Every project includes a 30-day warranty.
Have a project in mind? I'd love to hear about it. Whether you need an AI agent, a full-stack platform, or something that doesn't exist yet — let's build it.
