Sample Distributed systems and tradeoffs

Cafepress custom Search written in 2006 – indexer took ~13 hours for indexing cafepress catalogue and was later reduced  to 9 hours optimizing queries and using hadoop/map reduce.It was an offline indexing system.It was modified to handle real time updates by using message queues to capture updates and update index. indices were sharded across servers to improve performance.Search service was a multi layer service where requests were send to an aggregator service layer which was scattered to search slaves .The result was then aggregated result and returned.It was based on BASE and a highly available and performant system with 50-100ms response times.

Cafepress search was migrated to Elastic search a distributed search engine which includes indices that can be divided into shards, and multiple replicas in 2014-2015

Cafepress home grown A/B testing system(collect,analyze,adopt) and a data-driven mentality for all feature lauches for statistically significant  conversion lift  typically running experiemnts for at least 2-4 weeks and statistical significance at least 95%,continuous A/A testing,

Cafepress was modified to a social site with design feed(pull+push),follow designers,smart image upload adding in caching/load balancers(high availability)/sharding

Cafepress website/Workday app is horizontally scalable,secure and capable of handling sudden burst to traffic.Experienced with developing Monitoring and Anomaly detection in orders,microservices,CI,CD, development process optimization,containerization,production support

What is your ideal next job?

I have a breadth of experiences , masters in distributed systems,full stack experience  experience developing search systems,performant front ends ,apis and a passion for technology,architecture,customer friendly ideas,performance,scaling,efficiency. My recent efforts have been to optimize front end technologies but would love to be the entrepreneur employee who’s part of a great mission and has the flexibility to drive the technical/business vision, develop depth and experience in some newer big data frameworks and continue to learn,lead and grow taking on more responsibilities,calculated risks hiring,growing,scaling,inspiring great teams/services.

I suck at interviews .I almost always forget to explain my great experiences and learnings.Its a struggle to expose my knowledge and skills

 Favorite ideas/products you would like to be part of 

Self driving cars (take the monotony out of driving), google lens ,Love udacity/coursera (Online education/cheaper education/education as you need)

What would like to see in the future? 

Some thoughts while driving or ways to make our lives more efficient

  • Why should everyone own cars and waste garage space?
    • Cars/pods/gobblers as you need would be perfect.
  • Make distant distances reachable to minutes – Our ways to get far and quicker hasn’t changed much over the last few decades.Getting to destinations currently reachable in 1 hour could be reduced to matter of minutes(a great first step).
  • Remove offices and waste of office space – everyone offers services.HR service firms  could make it unnecessary for every company to rent spaces and own employees .Employees don’t have to have to drive to work
  • Online voting : why so we need mail/voting booths
