You will get a production-ready web app with seamless AI chat and automation integration
Project details
You will get a modern, production‑ready web app with a built‑in AI assistant that turns your content into a smart, conversational experience for your users. As a senior full‑stack developer and AI integration specialist, my focus is on clean architecture, reliable integrations, and a smooth handover so your team can easily maintain and extend the system.
Depending on the tier, your project can include anything from a high‑converting landing page with a basic FAQ chatbot to a full multi‑page application with RAG‑based AI search, automations (lead capture, CRM sync, internal workflows), and an admin dashboard. All projects follow a clear process: discovery, planning, implementation, testing, and deployment.
The workflow is characterized by transparent communication, clear milestones, and practical documentation so you always know what’s done, what’s next, and how the final solution works.

About Katja
Senior Full Stack Developer and AI Integration Specialist
Puerto Jimenez, Costa Rica - 8:12 pm local time
Alongside engineering, I've a long‑standing focus on nature and wildlife photography, which strengthens visual storytelling, composition, and UX intuition, which is useful when translating complex ideas into interfaces people actually enjoy using. My current freelance work prioritizes meaningful projects, especially those with positive social or environmental impact, where technology supports more sustainable and equitable outcomes.
On every project, my emphasis is on clean, well‑tested code, thoughtful architecture, and clear, proactive communication with stakeholders. I am comfortable owning work end‑to‑end or contributing within Scrum teams, with a track record of collaborating closely with designers, product managers, and non‑technical founders to define requirements and deliver dependable results.
If you need a senior developer who can quickly understand your domain, ship high‑quality features, and bring a detail‑oriented, analytical, and creative perspective, I'll be thrilled to help!
