Summary

Busi­ness Sys­tems Ana­lyst & Design­er, Soft­ware Engin­eer. Since 2020 I live in Aber­deen (UK), Aber­deen­shire, Scot­land. Tel: 07506 613 650, email: info @ jaroslawzelinski.biz. Now work­ing as a sole trader.

I am a sys­tems ana­lyst and design­er. I pre­pare busi­ness pro­cess mod­els (BPMN), require­ments such as use case mod­els and their spe­cific­a­tions (UML), doc­u­ment struc­tures and data dic­tion­ar­ies (UML). I design HLD sys­tem archi­tec­ture (microservices, micro applic­a­tions) and applic­a­tion integ­ra­tions using REST­full API (UML). I super­vise the imple­ment­a­tion pro­cess of the sys­tems designed by me. I con­duct train­ing in all areas that I deal with.

Soft­ware is more and more often part of a lar­ger elec­tromech­an­ic­al sys­tem, in which case the super­i­or elec­tromech­an­ic­al sys­tem is designed first and then its domain ele­ments, includ­ing soft­ware (SysML/UML).

I have been self-employed as an inde­pend­ent busi­ness ana­lyst, sys­tems archi­tect and con­sult­ant since 2005. I work for small, medi­um and large enter­prises (min­ing, man­u­fac­tur­ing and ser­vice also) and pub­lic admin­is­tra­tion. I have extens­ive exper­i­ence work­ing for small, medi­um and large com­pan­ies (require­ments ana­lys­is, busi­ness logic and soft­ware archi­tec­ture design using BPMN and UML nota­tions, sys­tem design using SysML nota­tion), cloud sys­tems, and NoSQL databases.

My pay rates (busi­ness ana­lyst, soft­ware and sys­tem engin­eer, imple­ment­a­tion super­visor): £50/h for retain­er con­tract, £75/h for T&M con­tract, £95/h ad-hoc (£50.000 annum for full-time contract).

30 years of expertise experience

in busi­ness pro­cess mod­el­ling, inform­a­tion sys­tems engin­eer­ing, require­ments eli­cit­a­tion, soft­ware archi­tec­ture design, sys­tems integ­ra­tion, busi­ness ana­lys­is, and extract­ing the busi­ness rules to base the busi­ness pro­cesses. Also author­ing super­vising for imple­ment­a­tion of designed sys­tems. Since 2005 I have been car­ry­ing out research and com­mer­cial pro­jects using one of the best CASE sys­tems: Visu­al-Paradigm.

Work­ing from 1991. Exper­i­ence: pub­lic sec­tor, a medi­um-large private com­pany in all sec­tors, busi­ness pro­cesses mod­el­ling and ana­lys­is, require­ment eli­cit­a­tion and inform­a­tion sys­tems design (e.g. one of the world’s biggest cop­per mine KGHM SA in Poland, pro­duc­tion main­ten­ance sys­tem mod­el­ling, IBM Max­imo imple­ment­a­tion super­vising, col­lab­or­a­tion with busi­ness and devel­op­ment teams). Design of integ­ra­tion and imple­ment­a­tion of PLM sys­tems, design of elec­tro-ener­get­ic-elec­tron­ic-com­puter sys­tems (mechat­ron­ic sys­tems). Many small, medi­um and big-size e‑systems were designed and super­vised by me. 

Pre­par­ing busi­ness pro­cess mod­els, inform­a­tion design and archi­tec­ture, sys­tem mod­els, and soft­ware archi­tec­ture (OOAD style using BPMN and UML/SysML nota­tions). Exper­i­ence in design­ing cloud repos­it­or­ies using the NoSQL tech­nic. Exper­i­ence with design­ing mechat­ron­ic sys­tems. Since 2005 I am also (vis­it­ing lec­turer, part-time) an aca­dem­ic lec­turer and researcher.

Models as the subject of research – my papers

Research­ing activ­it­ies from 1998. Over 30 art­icles in pop­u­lar domain news­pa­pers, a few reviewed sci­entif­ic papers, and one book (“Busi­ness Ana­lys­is. Prac­tice of enter­prise mod­el­ling”, became a best­seller in Poland, “Syn­thes­is of MOF, MDA, PIM, MVC, and BCE Nota­tions and Pat­terns” prin­ted by IGI Glob­al) and “Digit­al Doc­u­ments as Data Car­ri­ers and a Meth­od of Data Man­age­ment Guar­an­tee­ing the Unam­bi­gu­ity of the Recor­ded Inform­a­tion: Onto­logy-Ori­ented Data Man­age­ment and Doc­u­ment Data­bases.

I research mod­els as meth­ods . As an inde­pend­ent expert, ana­lyst and design­er, suc­cess­fully (engin­eer­ing issues: ) imple­ments pro­jects in the field of sys­tem ana­lys­is of enter­prises, design­ing logic and archi­tec­ture of inform­a­tion sys­tems, uses stand­ard, form­al meth­ods of ana­lys­is, which he con­stantly devel­ops and use in practice. 

As part of my sci­entif­ic work, as an inde­pend­ent expert, ana­lyst, and design­er, I suc­cess­fully imple­ment pro­jects in the field of sys­tem ana­lys­is of enter­prises, design­ing logic and archi­tec­ture of inform­a­tion sys­tems, using stand­ard, form­al meth­ods of ana­lys­is, which I con­stantly devel­op and use in prac­tice. I con­duct basic research in the field of meth­ods of sys­tem mod­el­ling analysis.

As a lec­turer from 2005–2012, I per­man­ently cooper­ated with the Inform­a­tion Sys­tems Depart­ment of the Mari­time Uni­ver­sity of Gdynia. Since 2014, I’m a lec­turer at the Fac­ulty of Inform­a­tion Tech­no­logy in Man­age­ment Tech­niques at the Uni­ver­sity of Inform­a­tion Tech­no­logy and Man­age­ment under the aus­pices of the Pol­ish Academy of Sci­ences. The sub­ject of lec­tures is sys­tems ana­lys­is and sys­tems logic design for busi­ness, form­al­ized busi­ness and sys­tems ana­lys­is aimed at optim­iz­ing the organ­iz­a­tion’s work, organ­iz­a­tion­al aspects of busi­ness con­tinu­ity man­age­ment, and devel­op­ing require­ments for man­age­ment sup­port software.

Since 2005 I use Visu­al Paradigm (VP) CASE soft­ware for all-pur­pose in my pro­jects. I use VP for all mod­els and pre­pare ana­lyses and reports (about 10 years ago I stopped using MS Office for writ­ing reports and sci­entif­ic papers). Coöper­a­tion with Visu­al Paradigm as a con­tent expert on a vol­un­tary basis.

After work

I’ve been liv­ing in Scot­land (Aber­deen) for some time. In addi­tion to work, dur­ing the day I admire the beauty of this coun­try and its dis­til­ler­ies and spend even­ings in pubs. If you want to meet me in Aber­deen, have a look at the folk ses­sions, I’m most often at the Blue Lamp pub on Mondays and North­ern Bar pub on Thursdays.
