AI and LLM engineering job support for backend developers

Your team just added an LLM feature and you’re the one who has to make it work in production. An AWS Certified AI Practitioner with a Java and Python backend background joins you over screen-share and works through it with you — from the first prompt to tool calling and agent workflows.

What we cover

What AI & LLM engineering covers

Java AI frameworks

Spring AI and LangChain4j inside existing Spring Boot or Quarkus services.

  • Spring AI
  • LangChain4j
  • Spring Boot
  • Quarkus

Python AI stack

LangChain pipelines and FastAPI services that wrap models and tools for the rest of your platform.

  • Python
  • LangChain
  • FastAPI

Claude and agentic workflows

The Anthropic API and Claude Code, tool use, agentic workflow design, and MCP integrations that expose your systems to models.

  • Claude API
  • Claude Code
  • Tool use
  • Agents
  • MCP

Prompts in production

Prompt engineering, structured outputs, and wiring model calls into services with timeouts, retries and logging.

  • Prompt engineering
  • Structured output
  • Observability
Sound familiar?

Where developers usually get stuck

  • The model’s output is almost right, but parsing it breaks one time in ten.
  • You need the model to call your existing REST APIs as tools.
  • An agent workflow loops or stops halfway through a task.
  • You’ve been asked to expose internal systems through an MCP server.
  • The AI feature works in a demo but is slow and expensive in production.
Custom requirements

Have a custom requirement? We’ll build support around it.

Every project is different. Tell us your technology, schedule and the help you need, and we’ll set up job support that fits — with a quote after the free scoping call.

Any stack or tool

Your project uses something not listed here? Tell us. We’ll say honestly whether our engineers know it.

Your hours

Sessions in your local working hours in any time zone, before stand-up, or around a release deadline.

One task or ongoing

One urgent ticket, a full sprint, or daily support for as long as the project needs it.

Extras on request

Interview prep, mock interviews, resume reviews and design walkthroughs.

Who you’ll work with

Education

M.S. in Systems & Software Engineering, with research on distributed transaction management in microservices.

Client stories

What developers say after working with us

Names are shortened to protect our clients’ confidentiality.

“The technical mentoring helped me work through complex Java, Spring Boot, and microservices challenges. The explanations were practical and focused on real-world development, debugging, and production troubleshooting.”

Michael A.USA · Java & microservices support

“I needed guidance with Camunda process orchestration, BPMN workflows, external task workers, and Java integration. The structured technical sessions helped me understand workflow implementation and resolve development challenges.”

Daniel F.Germany · Camunda BPM support

“The support covered React, Java, Spring Boot, REST APIs, and database integration. The practical approach helped me understand how frontend and backend components work together in an enterprise application.”

Omar H.Dubai, UAE · Full stack development

“The support covered React, Java, Spring Boot, API integration, and database operations. I especially appreciated the step-by-step explanations and practical examples that helped me troubleshoot full-stack application issues.”

Priya M.Full stack development support

“The sessions focused on Java microservices, exception handling, SQL queries, logs, and debugging production issues. The guidance was structured and focused on understanding the root cause instead of just fixing the immediate problem.”

Vikram P.Java microservices & production support

“I needed guidance across multiple technologies, including Java, Camunda, React, and REST APIs. The integrated approach helped me connect backend workflows with frontend functionality and build a better understanding of the complete application.”

How we work

Ground rules that protect you and your job

You stay at the keyboard

You share your screen and do the work; we guide, explain and review. You own your commits — that’s how the skills stick.

Your employer’s systems stay protected

We never ask for passwords or repository access. Please check your employer’s policies allow screen-sharing before you book. We don’t take on export-controlled (ITAR/EAR), classified or health-records work.

Confidential by default

We sign an NDA on request and never share who our clients are or where they work.

One engineer, one context

You won’t have to re-explain your project each time. Your engineer keeps notes on your codebase and goals.

How it works

From first call to confident on your own

  1. Free scoping call

    30 minutes on your role, stack, team rhythm and where you feel shaky. Share your requirement and we match you with an engineer who knows your stack.

  2. Schedule around your stand-up

    Sessions land in your local working hours — Americas, Europe, Middle East or Asia-Pacific — with a slot before stand-up if you want one.

  3. Work through your tickets together

    You share your screen and drive. We explain the code, debug with you, and review your changes before you open the PR.

  4. Taper off as you grow

    Most engineers move from daily to weekly sessions within a couple of months. The goal is that you no longer need us.

FAQ

AI & LLM engineering: common questions

Can’t find your answer? Email contact@jobsupport4u.com.

Do you support Java or Python AI stacks?

Both. Spring AI and LangChain4j on the Java side; LangChain and FastAPI on the Python side.

Which models do you work with?

Most of our hands-on work is with Claude through the Anthropic API. Spring AI, LangChain and LangChain4j also work with other model providers, so the same patterns apply.

Can you help with MCP?

Yes. We help design and build MCP integrations that expose your services and data to models safely, and wire them into agent workflows.
