SOFTWARE FOR BUSINESS · JAVA / KOTLIN · PRACTICAL AI

We build software that removes bottlenecks.

For companies in Poland, I design custom applications, backends and AI automation. I turn over 10 years of JVM experience into solutions that can be safely deployed and maintained.

01 / SERVICES

A concrete scope. One accountable partner.

I select technology for the process, risk and expected outcome. I do not force AI where a simpler system works better.

01 / AI

AI and process automation

Assistants, agentic workflows, RAG and LLM integrations connected to the tools already used by the company.

  • Controlled access to data and actions
  • Quality evaluation before production
  • Cost and human oversight under control
02 / PRODUCT

Custom applications

Web products and internal tools designed around the user's real process.

Kotlin · React · PostgreSQL
03 / BACKEND

Backend and integrations

APIs, distributed systems, JVM modernization and secure service integration.

Java · Spring · Ktor · Cloud
04 / DECISIONS

Architecture and audit

A review of risk, performance and change cost, ending with a plan that can be executed.

Architecture · Delivery · Quality

02 / AI IN PRACTICE

AI should perform work, not just hold a conversation.

A good AI system knows the right context, uses permitted tools and makes quality measurable. The model is one component, not the entire product.

Let us analyze your process
01

Context

Data, business rules and a clear task objective.

02

Tools

APIs and actions that let AI perform controlled work.

03

Quality control

Evaluation, observability, permissions and cost limits.

04

Human decision

Approval wherever an error has real consequences.

03 / EXPERTISE

Modern tools. A proven foundation.

I combine enterprise experience with the speed of a small team. I own the technical decisions, code, deployment and continued operation of the system.

10+

years of commercial work on web applications and enterprise systems

JVM

Java and Kotlin

Backends, integrations, microservices and systems that must remain stable.

AI

Integration, not a demo

AI connected to data, tools, evaluation and a real process.

OPS

Production included

Cloud, containers, monitoring and documentation are part of the solution.

Check the technical owner, public profile and working booking system instead of relying only on claims.

EXAMPLE SOLUTION LAYOUT

One path from interface to operations.

I select the scope for the process, data and risk, without hiding infrastructure behind a marketing diagram.

04 / COLLABORATION

From the first decision to working production.

GOOD FIT

I bring the most value when:

  • the problem combines product, backend and data,
  • the team needs senior decisions without expanding headcount,
  • the AI implementation needs a measurable goal and safe boundaries.
OUTCOME

You receive:

  • an explicit scope and architecture decisions,
  • working increments instead of a long promise phase,
  • deployment, monitoring and the knowledge required to maintain it.
01

Discovery

The problem, users, data and constraints before choosing technology.

02

Build

Short iterations, working increments and regular direction checks.

03

Launch

Deployment, observability, documentation and knowledge transfer.

STAWIARI · FOUNDER / SENIOR JAVA DEVELOPER

OTEKCODE has a technical owner.

I do not pass the project between sales and an anonymous team. You speak with the person who designs the solution and is accountable for delivering it.

05 / SHORT AND SPECIFIC

Common questions before a meeting.

Does every solution need to use AI?

No. AI only makes sense when it improves a specific process. If simpler automation is cheaper and more reliable, I choose the simpler solution.

How does the engagement begin?

With a short conversation about the problem, users, data and constraints. Its outcome is a sensible next step, not a sales presentation.

Can we start with an audit or a small scope?

Yes. An audit, technical prototype or first working increment often reduces risk before a larger investment.

06 / FIRST STEP

Let us start with a focused conversation.

Choose an available time. We will discuss the problem, constraints and a sensible next step, without a sales deck.
