Lead Software Engineer (Site Reliability)
JP Morgan Chase & Co.
Bengaluru, Karnataka
02.2022 - Current
- Architecting application instrumentation with custom metrics where applicable for on-premises and cloud applications using both open source and proprietary tools like JMX, OTel, DataDog, Dynatrace agents.
- Designing dashboards for visualization and tailored for varying audience levels from production management teams to c-suite members, with alerts set up triggering automated resiliency actions and run books thus helping avoid impacts to customers and shrinking MTTR.
- Creating Terraform based Infrastructure as Code (IaaC) deployment pipelines to automate paving, integration and testing of infrastructure end-to-end.
- Automating infrastructure scaling of distributed k8s pods and EKS, ECS and MSK clusters in combination with Attlassian approved terraform modules.
- Identifying and setting technical directions aligning with organizational goals to improve operational efficiency by reducing redundancy, streamlining processes.
- System design and architecture for application and infrastructure observability solutions with monitoring, and visualization for large scale distributed system to reduce MTTR. Breaking down larger problems into smaller individually executable work items, assignable to individual contributors.
- Experience architecting a business impact-driven, self-healing mechanism with automated resiliency actions based on SLO error margin burn-down rate.
- Ideated and architected Gray Area Resiliency solutions with automated failover operations for AWS services such as, MSK Reboot using AWS Lambda functions and step function flows.
- Designed the base architecture for the SLI, SLO metric generation, instrumentation, and selection of Golden signals aligning with business needs.
- Identifying usecases to optimize service performance ssuch as architecting for insights by monitoring observable async Kafka consumer thread pool activity to overcome partition to consumer count ratio limitations and increase concurrency.
- Embedding with Application teams in helping them migrate their application services from on-premises to public cloud, resulting in a hybrid operational structure.
- Giving back: Volunteered to Lead and mentor 2 teams of 8 in an SDLC project with Bachelor's students of Illinois Tech through ideation, requirements gathering, implementation, testing and release phases to deliver a full-fledged software solution, partnering with P33 Chicago. Writing technical blogs to share learnings and insights with the community. Blog

Skills
- I have not mentioned any languages that I can use to write code because, I have learnt over time and grown to a stage where any language is the same to me; except that the choice depends on the purpose to be served at hand It could be CUDA for asking GPU to do some work, python to write some data manipulation or ML model building code, R for matlab for a bit more math intensive computation, Java or C# for a backend with OOP, javascript for front/back-end, Assembly programming at times, SQL to talk to the storage and so on Essentially all we need is a coding language is to talk to a machine and the base framework of all the languages have a similar set of goals around executing code (either compiled or the interpreted)
