5 Ways to Prove You Can Do the Job Before Anyone Hires You

A resume tells a hiring manager what you say you can do. A short piece of real work tells them what you can actually do. If you are upskilling anyway, point that practice at a company you want to work for and your job search turns into a live demonstration.

Here are five ways to do that, in rough order of effort.

1. Act like an outside analyst

Pick a target company and study what is already public: their product interface, their digital footprint, their published data.

How to execute. Use the tools you are already learning — SQL, Python, web scraping, open-source intelligence techniques — to gather public information about the business. Look at their target audience, their geographic reach, and where their operations look strained.

What you practice. Real web scraping, data cleaning, and exploratory analysis, on messy data instead of a tutorial dataset.

Why it works. You are treating the company as a client. That shows you understand their commercial context, not just the syntax.

2. Send a "cold brief" instead of a cold email

Once you have analyzed the organization, package the findings into a one-page executive brief and send it to an engineering manager, team lead, or director.

Example. Pull a company's public client list or event directory, extract the location data, cross-reference it against regional economic or tourism datasets, and identify high-potential markets they have not entered.

What you practice. Data visualization, API integration, dashboard building.

How to open the message. "I noticed your team works heavily in X region. I combined your public client locations with regional growth metrics and found three emerging markets worth a look. One-page brief attached."

3. Find a pain point and bring a working prototype

Every business has friction: a clunky workflow, a slow query, no automated reporting, a security gap.

How to execute. Use their product and public endpoints. Find one specific inefficiency, then build a lightweight proof of concept that fixes it.

What you practice. Workflow automation, AI agent workflows, custom frontend components.

Why it works. Do not just name the problem — bring the fix. A two-minute screen recording showing the problem next to your working solution is far more persuasive than a paragraph describing it.

4. Publish a passive infrastructure or security review

For cybersecurity, DevOps, and systems people, proactive risk thinking is the strongest hiring signal there is.

How to execute. Run a non-intrusive, passive review of public-facing assets: TLS configuration, HTTP headers, API documentation clarity, accessibility compliance. Passive means passive — no scanning, probing, or testing that you do not have written permission to run.

What you practice. Standard diagnostic tooling and compliance frameworks.

How to present it. A clean "Security and Performance Recommendations" document: the risk, the impact on user trust or reliability, and the exact configuration or code change that fixes it.

5. Build a value-add tool for their users

Read what the company's own customers complain about on Reddit, X, or Discord, then build the small thing they keep asking for.

How to execute. If a product is missing a calculator, a browser extension, or an export feature that users request repeatedly, spend a weekend building a lightweight open-source version.

What you practice. Full-stack development, browser extension APIs, light database work.

How to reach out. "A lot of your users on Reddit were asking for X, so I built an open-source prototype over the weekend to see how it might work. Happy to share the repo and hear how your team prioritizes features."

The through-line

All five moves replace "please consider me" with "here is something useful I made about your business." That reframing is the entire trick. It also compounds: every brief, prototype, and report becomes portfolio material whether or not that particular company replies.

Two cautions. Keep everything you do passive, public, and permitted — never test, probe, or access anything you have not been invited to. And keep it short: one page, one prototype, one clear recommendation.

If you want a second pair of eyes on a brief or prototype before you send it, send it over. I have mentored hundreds of people and I am trying to reach a thousand.
