My core focus is designing, building, and deploying AI-driven systems—from LLM-powered agents and voice assistants to data-aware automation pipelines that integrate seamlessly with production applications. I work extensively with large language models (LLMs), retrieval-augmented generation (RAG), vector databases, embeddings, tool-calling frameworks, and agent orchestration patterns to create systems that reason, act, and scale reliably. On the backend, I build high-performance APIs and services using FastAPI, Flask, Node.js, and Django, with strong experience in async architectures, background workers, and event-driven systems. I regularly work with PostgreSQL, MySQL, Redis, MongoDB, and Neo4j, and design robust data layers using SQLAlchemy, Prisma, and ORM/DAO patterns. For AI workloads, I integrate OpenAI, Anthropic, Ollama, ElevenLabs, and custom inference pipelines, alongside Qdrant, Pinecone, FAISS, and hybrid search setups. On the frontend, I build modern, scalable interfaces using React, Next.js, Vite, Tailwind CSS, and TypeScript, with a strong emphasis on UX for AI-powered tools (real-time streaming, agent state visualization, conversation flows, and admin dashboards). For mobile, I work with React Native and cross-platform architectures to bring AI features directly into user-facing apps. Automation is a major part of my work. I design end-to-end business automation systems using Make.com, n8n, webhooks, cron jobs, message queues, and direct API integrations. This includes automating CRM workflows, email systems, call routing, lead qualification, reporting, and data synchronization across platforms like Twilio, Slack, Google Sheets, Stripe, Shopify, and internal tools. I’m highly experienced in AI voice agents and real-time systems, integrating Twilio, speech-to-text (STT), text-to-speech (TTS), streaming APIs, and conversational state management to build production-ready voice and chat agents. I also work on computer-vision and multimodal pipelines, combining vision models, tracking, and sensor data for advanced use cases. From an infrastructure and MLOps perspective, I deploy and scale systems using Docker, Linux servers, cloud VPS, CI/CD pipelines, and GPU-accelerated environments. I care deeply about observability, logging, error handling, security, and cost optimization in AI systems. Above all, I love turning business problems into automated, intelligent systems—reducing operational friction, increasing efficiency, and building products where AI is not a feature, but a core capability. If you need AI agents, automation pipelines, or full-stack systems that actually work in production, that’s exactly what I build. vähemmän

Whether you're launching a new AI-powered app from scratch or modernizing an existing codebase with smart features, I help businesses overcome common challenges: scope creep, endless revisions, delayed launches, and technical debt. My proven, structured process—honed through experience at Google and Apple—ensures efficient delivery, high-quality results, and lets you focus on marketing, go-to-market strategy, and scaling your business while I handle the tech. My Transparent, Client-Centric Development Process: - For Existing Codebases (Revamps, Upgrades, AI Integrations): I start with a thorough code review to understand your current architecture, strengths, and pain points. We then discuss your specific challenges and goals in detail. Next, I present a clear improvement plan with timelines, priorities, and expected outcomes. Once approved, I execute efficiently with regular updates—delivering faster, cleaner, and more scalable solutions. - For Projects from Scratch (New Mobile/Web/AI Apps): First, I deeply understand your vision and requirements through targeted questions and research if needed. I then create interactive prototypes (UI/UX wireframes or clickable demos) to visualize the product early. After your approval and feedback, I map out all user journeys and flows for complete clarity. Only then do we move to full implementation—ensuring no surprises. Every milestone delivery includes a detailed QA report showing how it was rigorously tested for functionality, performance, security, and edge cases. This battle-tested approach minimizes risks, accelerates time-to-market, and has consistently helped clients launch polished products in significantly less time—freeing them to prioritize growth and strategy. What You Get: • Cross-platform mobile apps (Flutter/React Native/iOS/Android) with AI features like chatbots, personalization, predictive analytics, or computer vision. • Full-stack web applications (React/Next.js + Node.js/Python + databases) enhanced with LLMs (OpenAI, Gemini, etc.) and custom automations. • Seamless AI integrations and workflow automations that save hours and boost efficiency. • Clean, maintainable code, CI/CD, cloud deployment (AWS/GCP/Firebase), and ongoing support. Clients choose me for reliable communication, fast prototypes, and results that drive retention and revenue. Ready to build or upgrade your AI-powered mobile/web solution the right way?
