Senior AWS Cloud & DevOps Engineer

I turn complex business challenges into secure, resilient, and cost-efficient AWS solutions — architecting scalable, production-ready platforms engineered for reliability and real-world impact.

How I work

Engineering approach

01

Own it end-to-end

Architecture, infrastructure as code, CI/CD, security, and production operations stay in one system, with no handoff that drops context.

02

Build for reuse

Terraform modules and pipeline templates that survive the original project — reducing configuration drift and the cost of the next deployment.

03

Integrate security early

OIDC keyless auth, least-privilege IAM, KMS encryption, and compliance controls built into the platform, not added after.

04

Automate the repeatable

Test gates, commit-SHA images, circuit-breaker rollbacks, and scale-to-zero scheduling — because manual processes degrade under pressure.

05

Observe before you need to

OpenTelemetry traces, structured logs, CloudWatch alarms, and cost dashboards — instrumented from the start, not added when something breaks.

06

Reduce cost thoughtfully

Fargate Spot, EventBridge scale-to-zero, and per-project Bedrock attribution, cutting spend where reliability stays intact.

About

What I do, and what came before

I design the platform, build the pipelines, and stay with the system after it is in production.

Before cloud, at Godrej & Boyce, I worked on defence-grade Linux and networking for autonomous military systems.

Where I've worked

Mar 2024
Present
aQb Solutions
Kolkata, India
Senior AWS Engineer
Lead cloud and DevOps for a UK automotive-finance and vehicle-leasing client: AWS architecture, infrastructure as code, CI/CD, security, and production operations.
Leadership & Enablement
  • Own engineering standards for infrastructure as code, CI/CD, and production support across the client development team.
  • Coach developers to handle routine DevOps tasks on their own, so delivery does not depend on one person.
  • Add AWS SDK calls to application code and ship them through peer-reviewed pull requests.
Platform & Delivery
  • Operate a 7-service self-serve microservices platform on ECS Fargate across staging, release, and production — with Claude AI code review as a mandatory PR gate on every service.
  • Built zero-downtime ECS pipelines: test gates, commit-SHA images, circuit-breaker rollback detection, and post-deploy ALB health checks.
  • Moved all repositories to OIDC with branch-scoped least-privilege deploy roles — eliminating long-lived AWS credentials from CI/CD.
  • Consolidated ETL infrastructure into one reusable Terraform module across 5 environments, with Multi-AZ RDS and deletion protection in production.
Scaling & Cost
  • Architected an elastic Fargate demo platform — 6 app instances from one parameterised Terraform config using setproduct, mixing FARGATE and FARGATE_SPOT with CPU target-tracking and EventBridge Scheduler scale-to-zero.
  • Designed per-project Bedrock cost attribution: dedicated IAM identities, CUR 2.0 + Athena/Glue pipeline, daily CloudWatch cost dashboard, and 4-tier AWS Budgets alerts.
  • Provisioned the AWS platform infrastructure (ECS Fargate, DynamoDB, S3, Secrets Manager, SSM Parameter Store) for a 10-portal vehicle-finance funder pricing service replacing a legacy RPA process.
AI Engineering
  • Provisioned Bedrock access to Anthropic Claude models in Terraform with EU inference profiles, per-project secrets, and keyless CI/CD access via STS external ID.
  • Architected and delivered an MCP-based AWS investigation agent — 8 audited read-only tools, immutable audit log, automatic secret redaction, 20+ formal delivery phases, 1,689 passing tests.
  • Deployed an AI compliance call-review service to production on ECS Fargate with full OpenTelemetry tracing and structured logging.

Zivanta Analytics
Kolkata, India
Senior AWS Cloud & DevOps Engineer
  • Migrated multiple production e-commerce platforms to Amazon ECS on Fargate, designing VPC, ALB, IAM, S3, EBS, EFS, SQS, SNS, SES, and Systems Manager infrastructure for availability and scale.
  • Built GitHub Actions pipelines for Docker-based ECS deployments with automated backups, disaster-recovery procedures, and migration playbooks.

Godrej & Boyce
Mumbai, India
Engineer
  • Worked on defence-grade IT, specialising in Linux and networking for secure, autonomous military systems.
  • Received an appreciation letter from the Indian Army MSL Regiment for excellence in engineering support.
  • Named Top Performer 2020–2021 in the PES-Service Department evaluation.
Projects

Selected engineering work

Each card is labelled production, implemented, or still a design. Case studies expand the two largest pieces of work.

AWS Infrastructure Investigation Agent
1,689 tests

Read-only MCP tools for EC2, IAM, ECS, CloudTrail, S3, and SSM. A terminal-state gate stops further evidence collection once a conclusion is recorded, and every response is redacted before it reaches the model.

Python 3.12 MCP Server ECS Fargate GitHub Actions SQLite audit log
Automotive Finance Self-Serve Platform
Production

TypeScript services and a React frontend for vehicle-leasing applications, with RDS PostgreSQL. Each service deploys on its own.

TypeScript ECS Fargate RDS PostgreSQL OIDC CI/CD Claude AI review
Elastic Multi-Tenant Demo Platform
Implemented

A Lambda reverse-proxy keeps task addresses off the internet. A self-deleting EventBridge schedule stops idle environments after an SSM-backed timeout.

Bedrock FinOps — Per-Project AI Cost Attribution
Production

Daily CUR 2.0 Parquet exports, queried in Athena, publish a CloudWatch DailyBedrockCostUSD metric per project. Budgets alert at 50%, 80%, 100% actual, and 100% forecast.

Amazon Bedrock CUR 2.0 Athena / Glue CloudWatch Terraform
KMS-Encrypted Alerting Pipeline
Implemented

Alarms publish through a customer-managed KMS key with annual rotation, then SNS, then a Lambda that notifies Slack and email. aws:SourceAccount conditions cover the SNS, SSM, and CloudWatch Logs principals.

FastAPI on ECS Fargate processes audio concurrently and calls Amazon Bedrock. Traces and structured logs go to OpenObserve. CORS origins come from Terraform-injected environment variables.

Production uses db.t3.large. Staging starts at 09:40 IST, runs the ETL at 10:00, and stops at 10:45.

An architecture and an early Go 1.26 skeleton, not a delivered product. Planned as 76 sections covering SAST, SCA, SBOM, DAST, containers, Prowler, and CI gates, mapped to PCI DSS, NIST, OWASP ASVS, and CIS. The MCP tool layer accepts Claude, Ollama, or any OpenAI-compatible endpoint.
