Leistungen für KI- und Produktentwicklung

Leistungen AI Sprint One month, one fixed price, one working result in production: an AI feature in your product, an AI agent that does a real job, or an assistant that answers from your own data. Leistung ansehen Leistungen Fractional CTO Anton Lytvynov, founder of Lytvynov Production, works as your part-time CTO: he makes the technical decisions with you, checks the people who build your product and keeps you in control of it, one or two days a week. Leistung ansehen Leistungen Technical due diligence A two-week, fixed-price review of a software product by a senior architect: what is solid, what is risky, what it will cost to fix, written so founders, investors and buyers can act on it. Leistung ansehen Leistungen Fractional CTO for startups For founders who are about to spend serious money on a first product and want a senior technical person on their side: before the vendor is chosen, while the MVP is built and when investors start asking technical questions. Leistung ansehen Leistungen AI proof of concept A short, fixed-price project that answers one question with evidence: can AI do this job on your data, accurately enough and cheaply enough to be worth building? Leistung ansehen Leistungen Fractional AI CTO For companies that want to use AI in their product or operations but have nobody senior to decide what is worth building, what it will cost every month and how to keep customer data safe. Leistung ansehen Leistungen Interim CTO When a CTO or technical co-founder leaves, someone has to own the technology the next morning. An interim CTO keeps the team shipping, secures what only the previous CTO knew and helps you choose the permanent one. Leistung ansehen Leistungen Independent code review For founders and managers who pay an agency or freelancers every month and cannot tell whether the work is good, whether the estimate is fair or what happens if the vendor walks away. Leistung ansehen Leistungen AI integration How we add LLM features to a product that already has users, data and a codebase, without breaking what works: architecture, guardrails, timeline and what drives cost. Leistung ansehen Leistungen Claude API integration How we build product features on the Anthropic Claude API: model tier choice, tool use, prompt caching, long documents, MCP, batch jobs, guardrails and running cost. Leistung ansehen Leistungen OpenAI API integration How we build product features on the OpenAI API: model choice, the Responses API, function calling, structured outputs, embeddings, migration from older APIs and running cost.

Leistung ansehen Leistungen Custom software development We design, build and maintain software that does not exist off the shelf: products you sell, systems your team runs on, and AI features inside both. Leistung ansehen Leistungen Custom CRM and ERP development We build internal business systems for companies that have outgrown spreadsheets and off-the-shelf CRMs: one platform where sales, operations, warehouse and management work on the same data. Leistung ansehen Leistungen MCP server development We design, build and host Model Context Protocol servers that let AI assistants search, read and act in your SaaS or internal system with each user's own permissions. Leistung ansehen Leistungen AI automation For companies that want repetitive back-office work done by software: which processes to automate first, when AI is needed and when plain rules are better, and how a rollout looks. Leistung ansehen Leistungen AI chatbot development How a custom AI chatbot that answers from your own knowledge is built: grounding with RAG, handover to people, channels, accuracy testing, timeline and cost drivers.

We build new Symfony applications, upgrade and rescue legacy PHP code, and provide dedicated Symfony teams for long-running products.

Leistung ansehen Leistungen AI consulting A short assessment that tells you which AI use cases are worth building, what they will cost to build and run, and what to do first, written by the engineers who would then build it. Leistung ansehen Leistungen Generative AI development How we build products whose core value is generated text or reasoning: copilots, document generators, writing tools and persona assistants, from model choice to quality control in production. Leistung ansehen Leistungen Dedicated team How a dedicated software development team from Lytvynov Production is put together, onboarded and managed, and what you should expect about reporting, replacements, ownership and cost. Leistung ansehen Leistungen AI product development The stages an AI product goes through between an idea and a product people pay for, what each stage must prove, and how we run them with our clients and for our own products. Leistung ansehen Leistungen React development We build React and Next.js web apps and React Native mobile apps together with the back end behind them, so one senior team owns the product from database to screen. Leistung ansehen Leistungen Software development company, Ukraine Who we are, how we work with clients abroad from Ukraine, how contracts and payments are set up, how we keep delivery running during the war, and what we build.
