- Developed and implemented an online trading platform for a global financial services company.
- Championed upgrade to a next-generation messaging framework (Aeron) for a global firm providing financial services in over 50 countries. 
- Two of my developments in GIS were patented back in mid-2000. I never minded but my mom was very proud.
- Mentored and trained junior team members at multiple companies, cultivating their skills and potential. 
- Recommended and implemented changes to deployment process which successfully switched two-hour error-prone manual procedure into automated “fire-and-forget” run.
15+ years of total Dev experience. Mostly Java including low latency, high-throughput, and Zero GC systems development for last 3 years. Bare metal Java but also some Spring (including Spring Boot and exotics like Spring Integration) and niche frameworks like jBPMN / Activiti or Domain-specific languages (DSL) with XText are tried; some worked well.
Database skills (mostly Oracle and MySQL) are quite extensive: enjoyed data architecting, SQL query optimisation and PL/SQL development for 10+ years but not too recent.
Had good time measuring performance (in terms of throughput / latency) of various modules and optimising those working slowly or consuming too much memory / CPU.
Will gladly help if your Java - related project got out of course and became too cumbersome to handle (I know not many people enjoy such work but I do not mind) or experiences performance problems.
