You will get Claude or OpenAI API integrated into your application

Project details
I integrate Claude, OpenAI, and other LLM APIs into existing applications — or build new AI-powered tools from scratch. I hold three Anthropic certifications earned in 2026 and have hands-on experience integrating 7 AI providers into a production SaaS platform. You get clean, documented code, clear communication throughout, and a developer who actually understands how these models work — not just how to call an API.

About Arnis
AI App Developer | Claude & OpenAI API Integration
Valmiera, Latvia - 6:35 pm local time
In March 2026 I led a team of four at the ZS/RTU Hackathon to build an offline-first AI assistant in 4 hours — parsing emails, extracting tasks, and generating summaries entirely on-device with zero external data exposure. Stack: FastAPI, Electron, and Ollama.
I hold three Anthropic certifications earned in 2026 — Claude with the Anthropic API, Claude Code in Action, and AI Fluency: Framework & Foundations. I'm currently building AICMA, a multi-user SaaS platform integrating 7 AI providers with calendar OAuth integrations and full Playwright test coverage.
My background is unusual for a developer. I'm a serving military officer with 15 years of operational experience. What that means practically: I work well under pressure, I communicate clearly, and I don't disappear when a project gets complicated.
If you need someone to integrate an AI API, build an agent workflow, or turn a messy idea into a working application — I'm straightforward to work with and I deliver.
