Expertise

Work Experience

Senior Technical Program Manager

  • Managed project planning and delivery through Scrum. Used Jira as the project tracking tool for daily standups, backlog refinement, sprint review, and other scrum ceremonies. Tracked sprints and release progress through burndown and burnup charts.

  • Developed a customer portal where customers can shop and place orders for products using Spring MVC. The UI is integrated into an SQL server database, and the application is also connected to a payment service for processing customer payments.
  • Created a Java solution that reads CSV files from a folder, extracts data, and inserts them into an Oracle database.

API Enablement Program

Launched and managed an API program with the core objectives of democratizing access to data and modernizing the application integration landscape across Schlumberger, the largest oil servicing company in the world.

I defined the program goals, identified sponsors, and secured $9.5 million in funding. The program involved three projects: build a marketplace that customers can find and subscribe to API products, set up an API management platform for securing and managing APIs, and promote API-first standards across development teams in four countries.

I managed the marketplace project, including application design, user experience, MVP scope definition, stakeholder management, and team creation. I launched the product within a 9-month timeline and a $3.5 million budget.

I led the API management platform research, assessment, and evaluation to find the right product and partner. I was involved in the partner selection—Google—and on price and contract negotiations. Google's API management platform was used by 10,000+ internal and external developers.

I organized numerous evangelism sessions across the organization to promote API-led integration. Also, I formed a community of practice for API enthusiasts to collaborate.

The program's impact has been broad: As of September 2020, there were 728 APIs published on the API management platform and 565 million monthly API calls.

SAP Migration Program

Managed the integration of 25 applications to the SAP ERP platform as part of the SAP migration program.

I managed a project that was part of a 3-year program to replace several ERPs and applications with SAP ERP. This was a global program affecting around 80,000 employees spread across 85 countries.

I acted as the integration project manager responsible for managing the SAP integration to internal and external applications. These applications included Salesforce CRM, Siebel CRM, Oracle ERP, Hadoop, Power Platform, SaaS and PaaS applications, and proprietary applications.

I managed a budget of $18.5 million and facilitated the implementation of 95 interfaces. I

I led the initiation and project discovery phase. Due to a large number of integrations, I created a template for collecting requirements from internal customers and stakeholders, building a backlog from these requirements.

I ran integration architecture sessions to define the integration strategy and patterns for different integration use cases. Integration methods included APIs, Boomi, smart data streaming, and SAP BAPI.

I also facilitated Scrum ceremonies and completed the integration project within budget and on time—18 months.

The integrations enabled several business processes, including order-to-cash, procure-to-pay, record-to-report, and product planning.

Order Provisioning Automation

Launched and managed the release of a customer portal for automating the order provisioning process for a telephony service.

The client could not keep up with the customer demand for its flagship telephony service. The order provisioning process was manual and required creating tickets to multiple teams to complete the process. This process took an average of three days, and it was prone to error.

I was tasked to initiate and manage a project to create a customer portal where the client's customers could place an order request for new telephony services. This request would automate the configuration of six applications—billing, ordering, BSS, OSS, mediation, and fraud applications—and three telecom equipment.

I ran the project and product discovery process, creating a project charter. The project was approved with a $550,000 budget and a timeline of five months and was completed on time and within budget.

I set up the team by recruiting four developers, one QA, and one UX designer, and created the backlog, leading Scrum ceremonies.

The customer portal was built with AngularJS. The process was orchestrated using Red Hat's jBPM. This controlled the API calls in the required order.

Order provisioning duration reduced from three days to two minutes. The revenue from the product grew from $5 million to $12.5 million due to an increase in orders.
