Decisions get easier
Software reads the messy inputs (documents, public registers, emails, spreadsheets) and puts the right information in front of the right person.
Your long-term partner for intelligent business systems Built with coding agents
Every business runs on knowledge that lives in people’s heads, spreadsheets and inboxes. I sit down with the people who do the work, learn how they make decisions, and turn that into software: tools that read, score, draft and check, so your team spends its time on the parts that need a human.
Coding agents changed what this costs. Apps that took months now take days, so it finally makes sense to build systems around every repetitive process.
People can now build apps in hours or days instead of months, thanks to coding agents. Every company should have someone on board who uses these tools to build software around every repetitive process in the business.
When every line of code was written by hand, that was impossible. Now you can have any business system you dreamed of, and keep it secure and maintained, by having the right person on board.
I can be that person.

Who I am, and why hire me.
What changes when you hire a business systems manager
I take what your people know about a process and build it into software. Three things happen.
Work gets faster
Repetitive steps run themselves. People review and approve instead of copying, pasting and chasing.
Deliverables get consistent
Your best person’s way of doing the job becomes the default, so every report, proposal and handoff meets the same bar.
Malleable software for every part of the business
Small, sharp tools, each shaped to one team, all changeable in days.

- See who’s overloaded before deadlines slip
Case studies
Two systems I built with coding agents. One is currently helping a construction company secure 6-figure deals by surfacing sales opportunities from unstructured governmental data, the other is an entire semi-autonomous business.
ProspPMBuilt for PM (pm.org.pl), a construction project-management firm
A fresh inbox of qualified sales leads, with phone numbers, every four days
PM wins work by reaching investors before construction starts. The signals are public: building permits, environmental decisions, pending applications. But they’re scattered across government registers, PDFs and unstructured Polish text that nobody has time to read.
Traditional scrapers collect every new record nationwide. Cheap filters drop the obvious misses, then an LLM reads each one the way PM’s best salesperson would and scores it against the firm’s profile. Good leads get the investor’s name and phone number attached, and land in a CRM where the sales team works them and managers watch the pipeline.
Giuseppe LabsAgent harness for restaurant marketing, giuseppelabs.com
A semi-autonomous business, built and run by coding agents
Giuseppe is an agent harness that lets restaurants run most of their online marketing from one chat. Owners send a message, a menu photo or a voice note. Giuseppe updates their website, keeps their Google profile in sync, drafts posts and review replies, and reports results every Monday. Nothing goes live without the owner’s one-tap approval.
Coding agents built and maintain every technical part of the business: the code, the infrastructure, the database, finding leads and onboarding new restaurants. The only work that needs to be done is meeting owners and selling.
Agent speed, without the shortcuts
Fast only matters if it’s safe. Everything I build follows the same rules, no matter who or what wrote the code.
Reviewed and tested
Agentic workflows review every change and run the tests. Then I test the app end to end myself, with agents testing alongside me.
Your data, your infrastructure
Systems run in accounts you own, in the regions you choose. You keep the code, the data and the keys.
Privacy designed in
Personal data is kept to what the job needs, access is least-privilege, and GDPR obligations are part of the design, not a patch.
Secrets stay secret
Credentials live in managed secret stores, never in code. Sensitive records go to AI models only when the task needs them.
Get the business system stack you always dreamed of
The agentic revolution in software is here. Turning repetitive work across the company into automated intelligent systems is finally affordable. Take advantage now.
