Professional Summary
Site Reliability Engineer with 5 years owning production reliability for high-traffic financial platforms. At Payvault Technologies, maintains 99.95% uptime on a payment processing platform handling 1M+ daily transactions - exceeding a published 99.9% SLA for 18 consecutive months. Reduced P1/P2 incident frequency by 60% through SLO-driven alert remediation and error budget governance; cut monthly toil from 40 hours to 7.5 hours through targeted automation. Takes a data-driven approach: measures error budgets, replaces metric-based noise with symptom-based alerting, and prioritises reliability work over reactive firefighting.

Work Experience
Site Reliability Engineer - Payvault Technologies
Sep 2022 - Present- Owns production reliability for a payment processing platform handling 1M+ daily transactions (peak 600 TPS during settlement windows); maintained 99.95% monthly uptime across 18 consecutive months, consistently exceeding the published 99.9% SLA and avoiding an estimated INR 4.2 crore in SLA penalty exposure.
- Defined SLOs and SLIs for 6 critical services in collaboration with product owners; error budget tracking shifted 30% of sprint capacity from reactive firefighting to proactive reliability work within 2 quarters, contributing to a 60% reduction in P1/P2 incident frequency over 12 months.
- Manages 20+ services across EKS clusters including version upgrades (v1.24 to v1.29), HPA tuning, pod disruption budget configuration, and node group scaling; completed 4 cluster upgrade cycles with zero unplanned service disruptions.
- Rebuilt alerting across the Prometheus/Grafana/Alertmanager stack, replacing 120 metric-threshold alerts with 28 symptom-based alerts on user-facing error rates and latency; on-call wake-ups fell from 11 per week to under 3, with zero missed genuine incidents.
- Led incident command for 6 Severity 1 incidents over 18 months; ran blameless postmortems and tracked all action items to closure; mean time to resolve P2 incidents fell from 90 minutes to 35 minutes, measured over 40 incidents.
- Eliminated 32.5 hours of monthly toil by automating 6 recurring operational tasks in Python and Bash (RDS failover validation, certificate renewal checks, deployment health gates, stale resource audits, snapshot lifecycle); engineer capacity recovered was reallocated to SLO improvement work.
- Ran a chaos engineering exercise on 3 services using AWS Fault Injection Simulator (pod deletion, network latency injection, and AZ impairment scenarios); uncovered 3 resilience gaps (missing retry logic, absent circuit breakers, misconfigured readiness probes) and closed all 3 before they caused a production incident.
DevOps / SRE Engineer - Skybridge India
Jun 2020 - Sep 2022- Shared on-call rotation for a B2B SaaS product serving 800 enterprise customers; reduced first-response time to production alerts from 22 minutes to under 6 minutes by improving alert routing and on-call escalation policies.
- Migrated monitoring from CloudWatch-only to a Prometheus/Grafana stack; set up scraping and dashboards for 8 microservices, giving the team per-service visibility into latency and error rates for the first time.
- Authored Terraform modules for EKS, ALB, RDS, and VPC; reduced infrastructure provisioning time for new environments from 4 days to 3 hours, used on 5 new environments in the first 6 months.
- Reduced EKS compute costs by 22% by implementing Cluster Autoscaler and rightsizing pod resource requests based on 30-day Prometheus utilisation data, without any increase in OOM-kill or throttling incidents.
Junior Systems Engineer - Infracore Corp
Jul 2019 - Jun 2020- Managed EC2, RDS, and load balancer infrastructure for a legacy web application serving 50,000 monthly users; maintained 99.7% availability across the year.
- Migrated a self-managed MySQL instance to RDS Multi-AZ; eliminated a single point of failure that had caused 3 unplanned outages in the previous year, each lasting 45-90 minutes.
