Position: BPM Consultant September 2016 – to date

Contracted for administration institution in Netherlands with main focus on IBM BPM solutions development.

IBM
Krakow, Poland, Europe
Position: Consultant June 2009 – September 2016

Joined technical professionals team supporting IBM business partners in middleware area. Team goal is to help business partners understand architectural and technical aspects of IBM solutions and apply them to customers’ problems. Such support ranges from technical guidance, thru deep-dive hands-on trainings and co-working, to proof of concepts and technical advocacy.
Focal areas of expertise, proven by certification, are smarter process (IBM BPM Standard from v7.5 to v8.5.5 and IBM ODM Standard from ILOG Jrules to ODM v8.0) and mobile ecosystem (IBM MobileFirst platfom, from Worklight v4 to MFPF v6.3).
Interlaced technology stack implies fundamental knowledge of other IBM technologies: WAS v8.x and Liberty Profile v8.5.5 application servers, BPM Advanced v8.x (ESB/IID) and Bluemix services.

Note. Due to team policy engagements are short, most of them do not exceed 2-3 weeks in total and are focusing on various and ad-hoc customer demands. Significant or long-running engagements are fraction and are emphasized below.
BPM adoption in public administration (2015)
  • On-site work in Africa for company working on government project and adopting IBM BPM in their branch. Delivered basic training and later bootcamp for technical staff on selected existing end-to-end process. Exercise was followed by certification for clients’ developers. I was later engaged in remote manner addressing specific design and implementation questions.
  • Skills used: BPM standard 8.5, Dojo Toolkit.
Mobile trainings residency in IBM Innovation Center (2014)
  • Series of remote engagements helping in adoption of IBM mobile ecosystem in South-Eastern Europe. Delivered dozen of deep-dive implementation workshops, presentations and mixed sessions. Live coding demonstrations were typical highlighting features specific to audience e.g. NFC/Bluetooth support to hybrid apps etc.
  • Skills used: IBM Worklight v5.x, JS, DojoToolkit, jQuery Mobile, Cordova, Android dev
Lab exercise design (2014)
  • I have designed and edited workbook for new laboratory exercise added to advanced implementation training delivered by my team. I have built supportive tools in Java to interact with JMS in Liberty Profile as part of exercise. As side effect I found and reported bugs on Worklight 5.0.3 JMS adapter version.
  • Skills used: Worklight, JMS, WAS Liberty Profile, Java JDK / Eclipse.
BPM for e-government project (2013-2014)
  • Singapore on-site implementation bootcamp on BPM Standard v8.0 was followed by addressing several issues business partner was struggling while developing e-government platform. Implemented skeletons of widgets showing cross-widget client-side communication using DojoToolkit pub/sub, prototyped multi-row selection tables with validation rules based on row content, in runtime instead of design-time.
  • Skills used: BPM standard 8.0, Dojo Toolkit.
BPM performance and troubleshooting (2012)
  • Mixed on-site and remote work in one of Arabic countries on BPM Advanced v7.5. Client was facing performance issues with XML processing and AIS bridge overheads. Worked actively with local IBM team to collect evidence, pass thru support and PMR process, and find workarounds.
  • Skills used: BPM advanced 7.5, AIS/ESB.
Pricing system for bank (2011)
  • One of national ISVs was validating ODM Standard for banking project. The goal was to crunch customer profiles with history of transactions using rules encoded logic and offer customized products pricing. I co-worked with ISV team on lazy-loading approach to data fetch from XOM model based on EJBs to cope with need for deep and rare data navigation in mass scale.
  • Skills used: ODM BOM/XOM modeling, JEE5 EJB.
Smart Metering prototype (2010)
  • Local energy sector IBM business unit was discussing with partner company a technology stack to support processing of smart meters’ data. I was tasked research on rules engine (BRMS ILOG JRules) feasibility in context of MDM/R VEE measurements validation module. Despite optimistic performance benchmarks I voted against BRMS in stack, due to initially-hidden static nature of rules.
  • Engagement offspring was BRMS article published in national energy sector newspaper.
  • Skills used: ILOG JRules, Java SE6.
