I build outbound systems
that bring ROI without adding headcount.

I'm Youssef Hesham. I work inside one revenue team at a time, for SaaS, ecommerce, and cybersecurity companies, and build the outbound systems an agency can't. Everything below is what those systems produced.

// the_systems · shadow tier

The shadow stack.

The same craft pointed at competitive and security intelligence: what a competitor is doing, what a target has left exposed, and the stealth layer the audits run on. Builds I can stand up and replicate. Press run on any system to watch it work.

// 8 systems · a few replay in the terminal above

Leak Radar01 blackhat

Darknet + paste-site leak intelligence. Watches breach dumps, Telegram channels and paste feeds for a target's domains, emails and credentials, and fires an alert the moment they surface.

→ tor · telegram · sub-hour alerts

Infra Change Watch02 blackhat

TLS + DNS adoption watchdog. Streams every new certificate a target issues and every DNS record they change, so a new subdomain, vendor or sending domain is caught the hour it goes live.

→ certstream · passive dns · spf

Email Stack Mapper03 blackhat

Email-infrastructure fingerprinting. Reads a company's MX, DKIM selectors and sending patterns to map exactly what they send with, and flags lookalike domains spun up to impersonate them.

→ mx · dkim · lookalike radar

Exposed Asset Scanner04 blackhat

Exposed-asset hunter. Sweeps a target for the things nobody meant to leave public: open S3 buckets, shared Trello/Airtable boards, exposed .git directories and env files.

→ s3 · trello · .git · airtable

Honeypot Collector05 blackhat

Funnel surveillance. A network of catch-all inboxes and seed identities that get enrolled into competitors' sequences, so their entire outbound funnel (copy, cadence, offers) replays back to me.

→ catch-all · auto-enroll · espionage

Stack Profiler06 blackhat

Shodan/Censys technographics. Reads a target's internet-facing banners and service fingerprints to profile their whole stack (servers, panels, vendors) without ever touching their site.

→ banner intel · zero-touch

Competitor Move Radar07 blackhat

Change-diff radar. Snapshots a target's pages, pricing and ad-library creatives on a schedule and diffs them, so a quiet price change, new landing page or fresh ad campaign pings me first.

→ snapshots · ad libraries · alerts

Stealth Proxy Fleet08 blackhat

Proxy + fingerprint infrastructure. The stealth layer under everything else: rotating residential exits and per-session browser fingerprints, so every scrape and audit runs clean and un-throttled.

→ residential rotation · stealth

// how I work

It's just me, and that's the point.

No agency, no account managers, no junior doing the real work behind a senior's name. I take on one revenue team at a time and build the systems into the way you already sell, at a depth an agency billing by the month never gets time for.

It isn't only the plumbing. I write the copy people thank me for getting, and I do the positioning, segmentation, roadmapping, and account scoring that decide who the machines even talk to.

On the first call I go through your current outbound with you and point at what I'd build first. That's the free teardown, no pitch.
