ABOUT · SALESFORCE ENTERPRISE DELIVERY DIRECTOR

The lead senior teams call when a program cannot fail.

15 years in enterprise IT, including more than 10 years of Salesforce implementation and delivery. L'Occitane, Sanofi, TotalEnergies, Lacoste, Disneyland Paris, Suntory, Affirma Capital. Complex programs where governance, compliance, and delivery consequences mattered.

Built my Salesforce foundation at Cognizant while helping scale its EMEA practice. I know where large delivery organizations create leverage and where governance can fail. That perspective shapes how I lead today: diagnosis first, time-bound, deliverables you own.

§ How I got here

15 years in enterprise IT.

I started in IT project delivery in Paris in the early 2010s. The first Salesforce engagement landed in 2012. The platform was becoming the operating layer for enterprise customer programs, and I followed that work.

From 2012 to 2016 I helped scale Cognizant's EMEA Salesforce practice from 5 to 200 consultants. I built the technical competency framework and graduate-to-consultant pipeline, and supported multinational RFP wins. Eighteen percent year-on-year account expansion across four consecutive years.

That is why I understand large delivery organizations from the inside. I helped scale one. I know how scope, staffing, commercial incentives, governance, and accountability interact. The transformation and delivery work I lead now is shaped by what I learned there.

When you engage me, senior accountability stays explicit from discovery through handoff.The working standard · since 2022

I left Cognizant in 2022 and continued in Salesforce transformation and delivery leadership. The case studies on this site separate the roles, dates, scope, and outcomes I can substantiate; confidential work stays unnamed.

§ What I do now

Three engagement contexts. One control standard.

Program Control Review. Fixed-scope review of decisions, governance, delivery risks, and integrator alignment for complex Salesforce programs. The work produces a sponsor-ready readout with options, owners, and handoff conditions.

Delivery Leadership. Permanent, interim, or embedded Salesforce delivery leadership when geography, contracting route, sponsor access, and decision rights work. The mandate covers scope, executives, partners, delivery governance, stabilization, and accountable handoff.

SI Partnership & Recovery. Senior subcontracting or client-side SI governance for recovery control, partner alignment, risk management, and accountable handoff when a program is drifting.

The common thread is program control: evidence before assertion, explicit decision rights, written risks and decisions, bounded scope, and handoff conditions the client can own after I leave.

§ One base, two regions

Seoul-based. EU and APAC delivery.

I am based in Seoul and work across EU and APAC time zones. Remote delivery is the default; travel is reserved for steering, recovery, and launch moments where physical presence changes the decision.

I do the same work in both markets: leading enterprise Salesforce programs end-to-end. Whether the client is a European group or an APAC enterprise, I shape the solution, align the executives, run the delivery, and rescue the ones that stall. Same person, same standards.

§ FAQ

Questions, answered.

What CTOs, SI delivery leads, and procurement teams ask before the discovery call. If your question is not here, email is the direct route; response timing is confirmed after review.

Who is Sébastien Tang?

Salesforce Enterprise Delivery Director based in Seoul. 15 years in enterprise IT, including more than 10 years of Salesforce implementation and delivery. Cognizant alumnus. I lead complex programs, governance, recovery, and accountable handoff across Europe and APAC.

What does an engagement look like?

Three engagement contexts: Program Control Review, Delivery Leadership, and SI Partnership & Recovery. Scope, decision rights, evidence access, and handoff conditions are confirmed before work starts.

How is this different from hiring an SI?

An SI provides scale and implementation capacity. My role is narrower: accountable senior program control, client-side or through an SI, with explicit decision rights, an evidence trail, and a written handoff.

Which industries and regions?

Pharma and life sciences, luxury retail, energy, financial services, entertainment. Direct delivery across France, BeNeLux, DACH and South Korea. EU and APAC time zones in the same week. English and French are the working languages; Korean is in progress and is not offered as a working language.

Direct engagement or via an SI partner?

Both. I can work directly with a client or through an SI that needs accountable senior delivery leadership. I am also open to selected permanent and interim roles.

What about Agentforce specifically?

An Agentforce pilot can stall because of data, permissions, Actions, testing, governance, ownership, support, or a weak use case. I treat those as hypotheses to verify, not as a universal top-two ranking.
