I build and maintain the technical side of small businesses — Linux servers, websites, hardening, automation, and getting found by both Google and the AI assistants people now ask instead.
Seven things, and they overlap more than most people expect. A site that ranks well is usually a site that is fast, patched and properly configured — so it is often the same job wearing different hats.
Setting up, tuning and babysitting Linux servers so they stay up. Provisioning, migrations between hosts, monitoring and alerts, and backups that have actually been restored at least once.
Ubuntu · Debian · nginx · Apache · Docker · cron · DNS
New builds or taking over a site that nobody has touched in three years. Plugin and theme updates, staging environments, speed work, broken-checkout triage, and moving hosts without losing email.
WordPress · WooCommerce · static sites · PHP · JS · HTML/CSS
Finding the open door before someone else does. Vulnerability scans, firewall and access rules, malware cleanup on compromised sites, patching schedules, and a recovery plan you can follow at 2am.
hardening · pen-test basics · WAF · 2FA rollout · incident cleanup
Wiring language models into the boring parts of a business — support replies, document sorting, data cleanup, internal tools. Built as scripts and APIs you own, not another monthly subscription.
Python · REST APIs · OpenAI & Claude · webhooks · scheduled jobs
People now ask ChatGPT and Perplexity the questions they used to type into Google. This is the work of making sure your business is what those answers cite — structured data, clean source pages, and content the models can actually read.
schema markup · llms.txt · entity clean-up · answer-shaped content
The technical half of SEO, which is the half most people skip. Crawl and index issues, Core Web Vitals, title and heading structure, internal links, redirects after a redesign, and honest reporting on what moved.
Search Console · Lighthouse · sitemaps · redirects · page speed
The thing you currently do by hand every Monday. Data imports, report generators, scrapers, file conversions, API glue between two systems that refuse to talk to each other.
Python · Bash · JavaScript · SQL · spreadsheets in, answers out
No discovery calls about discovery calls. Most projects go from first email to work starting inside a week.
Send the form below or an email. Describe it in plain language — "the site is slow" is a perfectly good brief. I will ask for access only when I actually need it.
I look at what you have, then quote a flat price and a date for the whole job, or an hourly rate for ongoing work. If it is out of my depth, I say so.
You get progress notes as it goes, documentation at the end, and everything in accounts you own. Leaving should be easy, or I have not done the job right.
I am an undergraduate at the University of California, Davis, studying the systems side of computing — server administration, networking, cybersecurity, and AI programming. Qichao Ma Enterprises is how I put that to work on real problems instead of only coursework.
Which means you get the honest version of a freelancer: one person, no agency markup, no account manager relaying messages, and a strong incentive to do good work because my reputation is the entire business. I am independent and remote, so clients anywhere are fine — I have worked across time zones since the day I started.
If your problem is bigger than one person should take on, I will tell you that up front rather than take the money and learn on your server.
Leave your name and email and I will write back with questions about your project, availability, and what it is likely to cost. No newsletter, no drip sequence, no sales call you have to escape from.
