AI applications.
Workflow automation.
Custom software.

I'm Felix, an independent developer based in Wuxi. I turn business needs into useful tools and finished work, from one feature to a phased application project.

Start with a real task.

Service examples, not past client cases.

Turn an inquiry into a draft

Bring scattered messages together into a requirements summary, open questions and a quotation draft.

Ask your company documents

Search approved documents and show the supporting sources alongside the answer.

Add a useful business feature

Add an agreed quotation, approval or reporting feature to the application your team already uses.

Six ways I can help.

Build it for you, work with your team, or deliver the finished output.

Workflow automation and custom agents

Connect messages, documents and business systems, with review at consequential steps and visible failures.

Typical delivery

A working workflow, agreed integrations and an operating guide.

Knowledge and document applications

Find answers in company documents with sources, extract fields, or consolidate and check spreadsheets.

Typical delivery

A reusable application with checked sample outputs.

Web development and product prototypes

Build a website, quotation tool, client portal or first usable product. Add an agreed feature to an existing application.

Typical delivery

An agreed prototype or application, source handover and deployment instructions.

AI work setup and practical coaching

Apply AI to a real task in research, reporting or coding, starting with your current tools and experience.

Typical delivery

A configured workflow, a guided task and reusable materials.

System diagnosis and improvement

Investigate broken features, import errors, weak retrieval or workflows that stop midway. Diagnosis can be a separate engagement.

Typical delivery

A reproducible diagnosis, agreed correction and before/after checks.

Research and finished deliverables

Receive a sourced product comparison, organized records, a presentation or an agreed information brief.

Typical delivery

A finished report, spreadsheet or document in the agreed format.

Personal project

RAGX

Knowledge retrieval, with evaluation.

A personal project exploring document Q&A with cited answers and quality evaluation. It is a reference for how I approach retrieval and checking, not a paid-client case.

Cited answers & evaluation

My background includes enterprise software delivery and React/TypeScript development.

Clear scope. A useful handover.

Confirm feasibility before committing to price and timing.

Start with a small, separately agreed piece of work.

A diagnosis can be a separate engagement. Before implementation, agree the deliverable, acceptance checks, access needed, price and timing. For an application change, discuss source handover and deployment instructions; ongoing support is scoped separately.

  1. Understand the task

    Share the current process, desired result and available samples. Confirm data and system access.

  2. Agree the work

    Define deliverables, acceptance checks, stages, price and timing. Make the boundaries explicit.

  3. Build, check and hand over

    Deliver the agreed result with checks and guidance. Scope ongoing support separately.

What would you like
to get done?

  1. What do you do manually, or what is broken?
  2. What would a useful result look like?
  3. Which tools or systems are involved?

Start with a short description. Do not send passwords or confidential customer files in the initial enquiry. A redacted example can be discussed if needed.
