About me

Portrait of Devesh Saini

I'm a site reliability engineer who treats production like a product: measured, automated, and boring in the best way. Over the years I've moved workloads to Kubernetes, rebuilt CI/CD pipelines, and put observability in place before incidents demanded it.

Off-call, I ship small mobile apps — partly for fun, partly because building the whole thing keeps my empathy for developers sharp.

What I do

Site Reliability Engineering

SLOs, error budgets, incident response and blameless postmortems — reliability as an engineering practice, not a hope.

Cloud Architecture

AWS and GCP design, multi-region setups, migrations and cost optimization that pays for itself.

Kubernetes & Containers

Cluster design, autoscaling, hardening and the boring operational discipline that keeps workloads healthy.

CI/CD & Automation

Pipelines, GitOps and release engineering — from commit to production without human toil.

Observability

Metrics, logs and traces with Prometheus, Grafana and OpenTelemetry. See problems before customers do.

Infrastructure as Code

Terraform and Ansible for infrastructure that is reviewed, versioned and reproducible.

// career

Experience

2026 — Present

Solutions Engineer @ Smartsheet

Bridge engineering and customers for a leading work-management platform — designing technical solutions, building proof-of-concepts, and translating reliability and integration requirements into working implementations. The engineer in the room when the answer has to actually run in production.

2024 — 2026

Associate Consultant (SRE) @ Lingaro

Site reliability for enterprise data pipelines — kept large-scale ETL and analytics workloads healthy for global clients. Built Grafana dashboards and alerting that caught pipeline failures before business reports broke, and automated recurring incident toil across the platforms I supported.

2022 — 2024

Site Reliability Engineer @ Wipro

Ran production Java web applications on Linux — deployments, monitoring, incident response, and root-cause fixes. Automated routine operations with scripting and hardened the environments I supported, keeping the applications I owned stable and boring in the best way.

Engineering log

Migrated the homelab to k3s 1.33

Single-node to 3-node HA. Etcd snapshots to S3-compatible MinIO. Longhorn for storage.

TIL: ALB connection draining vs pod terminationGracePeriod

They must agree or you drop requests on deploys. Wrote a preStop sleep hook into our base chart.

Shipped ShiftBell v1.2

Handoff notifications now respect quiet hours. First feature built entirely from user feedback.

Load-tested the blog with k6

1,200 rps on a $5 VPS thanks to SQLite + one Node process. Boring tech wins again.

What teams say

Devesh rebuilt our deployment pipeline and our on-call stopped being a nightmare within a month. The postmortem culture he introduced outlasted his contract.
Priya RamanVP Engineering, FinEdge
Rare mix: deep infrastructure knowledge and the patience to teach it. Our cloud bill dropped 40% and the team understood why.
Marcus ChenCTO, CloudScale
Handed him a fragile legacy stack; got back Terraform, runbooks, and a team that ships daily.
Sarah OkaforHead of Platform, HostWorks

Common questions

What kind of projects do you take on?

Cloud migrations, Kubernetes setups, CI/CD pipelines, observability rollouts and reliability audits. Anything from a one-week infra audit to a multi-month migration.

Do you work remotely?

Yes — I work with teams worldwide, async-first, with overlap hours agreed up front.

What does an engagement look like?

We start with a short call, I scope the work into a fixed plan with milestones, and every project ends with documentation, runbooks and a handover session for your team.

Can you support us after the project?

Yes. The SRE Retainer covers ongoing reliability work, incident support and monthly reviews — or 30 days of support is included with every project.

What does a Site Reliability Engineer actually do?

An SRE keeps production systems fast, available and cost-efficient by treating operations as an engineering problem: defining SLOs, automating away manual toil, building monitoring and alerting that catches issues before users do, and running structured incident response and postmortems when things break.

Do you work with early-stage startups or only larger teams?

Both. For early-stage teams the work is usually foundations — CI/CD, infrastructure as code, monitoring and a sane on-call setup done right the first time. For larger teams it is usually reliability at scale: SLOs, incident process, Kubernetes and cloud cost work.

Can you improve our AWS bill without risking reliability?

Yes — in a specific order: first remove idle resources (typically 15–25% of the bill, zero risk), then rightsize from real utilisation data, then schedule non-production environments, and only then lock in savings plans. Reliability is checked at every step; savings that create outages are not savings.

Do you work remotely and across time zones?

Yes. I work remotely with teams across time zones, keep an overlap window for meetings and pairing, and put everything else in writing — decision docs, runbooks and recorded walkthroughs — so the work never blocks on my calendar.

What happens when the engagement ends? Will we depend on you?

The explicit goal is the opposite of dependency. Every engagement ends with documentation, runbooks and a handover session so your team owns and operates everything I built. You should not need me for day-two operations — only for the next project.

Which technologies do you work with most?

Day to day: AWS, Kubernetes, Terraform, Docker, GitHub Actions and other CI systems, Prometheus and Grafana for observability, and Python or Go for tooling. The principles — SLOs, automation, capacity planning — transfer to whatever stack you already run.
