Agentic AI development services for real workflows
I am Sebastian Schkudlara. I design and build AI systems that work with real data, APIs, tools, permissions, and human review.
The goal is one useful workflow your team can inspect and operate. That may be a RAG system, a tool-using agent, or a simpler backend service with one well-placed model call.
Good fit
- A prototype works in a controlled demo but fails with real data or users.
- A workflow needs internal documents, APIs, search, or business tools.
- The team needs clear permission, approval, evaluation, and rollback boundaries.
- An engineering team can build but needs senior AI and backend architecture support.
Start with the scope you actually need
Workflow audit
Map one workflow, its users, data, tools, risks, and approval boundaries. You receive a decision memo, an architecture sketch, and a credible first implementation slice.
Build or pilot rescue
Implement one end-to-end workflow or repair a prototype that fails outside the demo. The agreed scope covers integration points, evaluation cases, deployment notes, and operational handoff.
Fractional architecture support
Give an existing team architecture review, implementation planning, model and vendor decisions, evaluation support, and engineering unblock work for an agreed period.
What I build and improve
Agentic AI application development
Build a focused application that can retrieve context, call approved tools, keep the right state, and hand decisions back to a person when required.
Typical work includes backend APIs, tool contracts, model integration, approval paths, tests, and deployment. The agent receives only the access needed for its job.
Typical output: one working workflow, documented integration boundaries, evaluation cases, and an operational handoff.
RAG and knowledge systems
Turn documents and changing business information into context an application can search, inspect, and cite.
The work can cover extraction, chunking, metadata, retrieval, reranking, source display, access controls, and quality checks. A fluent answer should never hide a broken data path.
Typical output: an ingestion and retrieval slice with test questions, source evidence, and a clear update path.
AI integration and model routing
Connect models, search, APIs, databases, and existing backend services without making one vendor the permanent center of the application.
I define stable interfaces around model calls and tools, keep provider-specific behavior behind replaceable boundaries, and use deterministic code where an agent would add risk without value.
Typical output: integration contracts, routing decisions, error handling, and a working API or backend slice.
Evaluation and safe operations
Add the evidence needed to see whether an AI workflow is improving or quietly failing.
That can include representative cases, regression checks, traces, cost and latency visibility, approval queues, failure categories, and rollback paths. The evaluation follows the workflow, not a generic model leaderboard.
Typical output: an evaluation set, operational checks, a review process, and a prioritized failure backlog.
Document and multimodal workflows
Build reviewable paths for PDFs, scans, images, structured files, audio, or video before those inputs reach retrieval or reasoning.
Extraction stays separate from interpretation. People can inspect what the system read, correct it, and reject poor input instead of debugging only the final answer.
Typical output: an extraction and review pipeline with explicit data-handling and retention boundaries.
Pilot rescue and delivery support
Find out why an AI pilot does not survive real use, then help the team ship the smallest credible production slice.
I can support a product team directly or work behind the scenes with an agency or consultancy when delivery gets technically deep.
Typical output: a production-risk assessment, implementation plan, and focused architecture support for an agreed period.
Problems worth bringing
Internal knowledge search
Search policies, manuals, reports, or project material with access-aware retrieval and visible sources.
Research and comparison
Collect current evidence, remove duplicates, compare claims, and keep citations attached to the result.
Operational assistants
Read from approved systems, prepare a proposed action, and wait for human approval before anything consequential changes.
Document-heavy processes
Extract files, validate structured fields, show uncertain results, and route exceptions to a person.
Prototype hardening
Replace hidden prompt logic with explicit workflow steps, tool contracts, evaluation, logging, and rollback behavior.
System integration
Connect a model-driven workflow to existing APIs, databases, queues, and business tools through clear contracts and failure handling.
From workflow map to production slice
Code and engineering notes where I can share them
I would rather link to concrete work than fill this page with broad claims.
Before we talk
What is agentic AI application development?
It is the engineering behind an AI system that can choose steps, use approved tools, retrieve context, and maintain workflow state. Production work usually centers on permissions, integration, evaluation, failure handling, and human review.
Do I need an AI agent or a RAG system?
Use RAG when the main job is finding information and answering with sources. Add agent behavior when the workflow must choose tools, perform dependent steps, or prepare an action. Some projects only need a normal backend service with one model call.
Can you work with an existing prototype?
Yes. I first map the real workflow and find where the prototype fails, such as data quality, retrieval, tool access, state, evaluation, latency, cost, deployment, or ownership.
Do you require a specific model or framework?
No. The workflow and operating constraints come first. Existing choices can stay when they fit. I keep provider-specific behavior behind replaceable boundaries where that is practical.
How does a project start?
Send a short description of one workflow, the systems it touches, and what currently fails, takes too much manual work, or needs to be built. I will tell you whether an audit, pilot rescue, build slice, or another route makes sense.
Send one workflow
Use the contact form to describe the problem, the systems involved, and what currently fails, takes too much manual work, or needs to be built. I will reply with the most useful next step I see.
