Technical leadership for Amazon's networking teams.My main focus is on SDN controllers that reduce network cost, improve network performance, and avoid the large blast radius of centralized traffic engineering.

Tech and product leadership for Gemini Credit Card and web & mobile front ends. Led multi-disciplinary teams totalling 100+ employees.

All things tech in a fin-tech. For example, guidance on a new blockchain integration layer allowing the exchange to onboard blockchains in weeks instead of months, and thereby reduce time to market of new crypto assets.

Think and build the future of Amazon CloudFront, AWS's CDN. As the main individual contributor in a team of hundreds of engineers, I was responsible for the overall technology strategy. For example, I led a 5-year project to change and consolidate CloudFront's architecture, ultimately allowing the service to scale for world's largest live-streaming events such as the Super Bowl. Among other things, that project included a new hardware architecture, a disruptive change to the content placement system, and the adoption of proprietary video streaming protocols. Under my tenure, CloudFront maintained positive margins and increased market share all the while the CDN market observed year-over-year double-digit price compression.

Invent, design, implement, test and operate Amazon CloudFront. Mentor and advise engineers and leadership alike. Technical lead for projects such as deploying CloudFront to AWS's China partition and the reduction of network congestion events by more than 98%.

App77 is the one-man company for my 5 years experience as an indie developer. Therein, I built and commercialized a password manager app for iOS and Mac with an associated server-side component that has 50K+ daily active users.

At The Pole, I was mostly a business person, one of the 3 founding partners. My main responsibility was to be the technical bridge between the panel operators and the development team for The Pole Society HQ in Romania.

Besides my responsibilities as a board member, I ran the software development team, which produced and operated an instagram-like social network. As an startup CTO, I also designed the distributed system and the iOS app.

As a founder and active partner of this ISV and contracting shop, I did a little bit of everything: managing a small team of developers, coding & system design, customer relationship, general business management, and sales. Duom's product was Andarta, a distributed BI system based of a self-organizing ad-hoc network which I designed.

At 3Corp, I managed a team of 10 software engineers that was responsible for Vocale, a voice recorder system for Alcatel PBXs.

Responsible for R&D team management and strategic product planing. Among other things, I have personally designed and successfully delivered most of Aker network products during the six-year period I've worked there, assembling and leading a team of 20+ developers on two distinct sites and acquiring professional services from domestic and foreign suppliers. Notable deliverables were a from-scratch IDS system, a multi-node active-active firewall cluster. Lots of in-depth, inside the kernel designing and coding.

Designing and implementing cryptography-related software and hardware products. Providing on-site support for military clients.

At the Herzogenrath (Germany) research lab, designing a XML-defined service oriented IP/IPv6 routing protocol. Succesfully built a working prototype.

Desiging signal aquisition modules for PLCs and writing technical manual in English and Portuguese.
