Ways I plug in

DiagnoseA low-commitment way to get unstuck.

Best for: a product launch or roadmap that's drifting.

  • Written breakdown of product and technical gaps
  • Build vs. buy direction on key decisions
  • Compliance, operations, and privacy issues called out
SpecializeDeep, hands-on experience in payments, fintech, and AI.

Best for: payments, identity, or AI work that needs someone who's been there.

Payments & fintech

10+ years at PayPal, Braintree, Olo, and Paxos.

  • Billing and multi-party payout integrations (Stripe, PayPal, etc.)
  • Embedding payments into products where payments aren't the core
  • Working with legal, ops, compliance, and data teams to ship in regulated spaces

AI products & automation

From product launches to internal automation.

  • Sorting where AI actually pays back from where it doesn't
  • Internal tools that replace manual work and actually get used
  • Shipping AI features into existing products without breaking them
  • Guardrails on data handling, PII, and prompt behavior
EmbedOngoing product & tech lead, or coverage between hires.

  • Product process that fits where you're at and your size
  • Writing the actual specs, stories, and docs
  • Being there when your team needs backup on hard product and technical calls

What clients say

Jamar provided a great mix of subject-matter expertise and true depth on identity and KYC, plus the ability to evaluate forward-looking theses. His approach, thoughtfulness, and insight were most valued.
Fintech company, growth stage
From the start, it was clear Jamar truly understood our needs. His hands-on help with Stripe payment processing setup was invaluable. His forward-thinking approach has set our team up for success long-term.

Not just advising. Building.

Alongside client work, I'm building my own products. I bring lessons and perspective from that back into the fractional work.

A little background

Jamar Parris

I'm Jamar Parris. I've spent 18+ years shipping product across PayPal, Salesforce, Braintree, Paxos, Olo, and BNY from startups to enterprise, mostly in fintech, payments, identity, and now AI workflows.

I work fractionally because the kind of help I'm best at usually takes weeks, not years. Most engagements end with me writing myself out of a job. That's the goal.

Outside of fractional work and building, I'm into hiking, travel, and photography.

Common questions

How do you charge?

Two starting points:

  • Hourly for short, exploratory work: a pre-launch review, a build vs. buy call, a second opinion. Low commitment, fast start.
  • Monthly retainer for reserved capacity: open-ended for ongoing product and tech work, or time-boxed for leave coverage and clean-cut projects.

We shape it to what you actually need.

Is the 15-min call actually free, or is this a sales call?

Free, genuinely. If we're a fit, you'll know. If we're not, you'll have saved us both time. About half of these calls end without an engagement, and that's fine.

Do you only work in payments, fintech, identity, and AI?

Those are where I have the most depth and can be useful fastest. I take on adjacent work (B2B SaaS, marketplaces, regulated industries) when the problem maps to patterns I know. If it doesn't, I'll say so.

Can I just email instead?

Sure. The contact form lands in my inbox, no different than email. The 15-minute call is usually faster for both of us, but either works.

Unblock yourself.
