I have spent 30 years in enterprise sales across tech, healthcare, and data-heavy industries. I have closed deals, built pipelines from scratch, and rebuilt revenue systems that stalled. I know what a broken funnel looks like before the client does.
I run Revenue Alchemy, a B2B revenue consulting practice. I work with founders, sales leaders, and growth teams who are generating activity but not predictable revenue. The problem is rarely effort. It is usually architecture.
Before I recommend anything, I diagnose. I find the real constraint in your deal pipeline, whether that is a trust gap, a leaky funnel, a positioning problem, or a scaling ceiling. Then I install the fix in the right order.
What I do on Upwork:
B2B Lead Generation and Prospect Lists. Clean, verified, targeted lists built to your exact ICP. Not volume. Precision. Every list is reviewed before delivery, so you are not cleaning data before you can use it.
LinkedIn Outreach Strategy. Sequence design, messaging frameworks, and connection strategy built for B2B decision-makers. I have run enterprise-level LinkedIn outreach. I know what gets a response and what gets ignored.
Email Outreach and Cold Email Systems. Campaign strategy, sequence writing, and list matching. Built to convert, not just to send.
Sales Process Diagnostic. If your pipeline is full and your close rate is low, something is broken upstream. I find it.
Revenue System Builds. For clients who need more than a list or a sequence. Full GTM architecture, ICP definition, offer positioning, and outreach motion, built to run without you doing everything manually.
For list-building and prospect research projects, my team operates under my direct oversight. I review every deliverable before it reaches you. Work starts at $35/hr for execution-level projects. If you want my personal involvement in strategy, ICP definition, or outreach architecture, that is a separate engagement priced accordingly.
What makes this different:
You get 30 years of enterprise sales judgment on your project, not a junior VA running a tool. I oversee every engagement, review every deliverable, and tell you what I actually think. If your brief does not align with your goal, I will tell you before I start, not after.
📌 Important Note
I work with a small, focused team that handles execution under my direction. For clients who want my direct involvement in strategy and system design, this is available through a separate consulting engagement with different pricing.
Ready to get started?
Send me a message with your industry, your ICP, and what you are trying to fix. If it looks like a fit, I will send a short 15-minute intro call link so you can confirm I am a real person before we move forward.
Let's find the real constraint and fix it.

I help U.S. businesses navigate SMS approval, deliverability, and compliance requirements - reducing the risk of carrier rejections, blocked traffic, and regulatory issues.
I specialize in A2P SMS compliance and deliverability, including 10DLC registration, Toll-Free Verification (TFN), and TCPA/CTIA consent audits, as well as diagnosing carrier-level delivery problems. My work focuses on aligning SMS programs with current carrier and regulatory expectations so they can operate and scale responsibly in the U.S. market.
If your messages are being rejected, filtered, or delayed - or you’re unsure whether your consent flow and use case will withstand carrier or legal review—I can help assess and correct the underlying issues.
What I Do
• 10DLC brand & campaign registration (new submissions, rejections, reclassifications)
• Toll-Free Verification (TFN) setup and resubmissions
• TCPA / CTIA compliance audits (opt-in flows, disclosures, opt-out handling)
• SMS deliverability diagnostics (carrier filtering, content flags, throughput limits)
• Platform-specific guidance (Infobip, Twilio, GoHighLevel, ClickSend, SimpleTexting)
• Compliance-aware SMS automation (webhooks, triggers, rate-limiting, quiet hours)
