Technical Expertise

Core AWS Services We Deliver

Deep technical capabilities across the full AWS portfolio — built for enterprise reliability and startup agility.

Amazon EC2

Right-sized compute instances — from burstable T-series to compute-optimised C-series and memory-optimised R-series. We architect Auto Scaling Groups, Launch Templates, and Spot Fleet strategies to cut compute costs by up to 70%.

Instance right-sizing & family selection
Auto Scaling Groups (ASG) with target tracking
Spot Instances & Savings Plans
AMI hardening & golden image pipelines
Placement Groups for HPC & low-latency

Amazon S3 & Storage

Scalable object storage with lifecycle policies, intelligent tiering, and cross-region replication. We design S3-based data lakes, static website hosting, and archival pipelines with Glacier Deep Archive.

Bucket policies, ACLs & IAM integration
S3 Intelligent-Tiering & lifecycle rules
Cross-region replication (CRR/SRR)
S3 Event notifications & Lambda triggers
EBS, EFS, FSx for Windows/Lustre

Amazon ECS & EKS

Container orchestration on AWS Fargate (serverless) or EC2 launch types. We manage full CI/CD pipelines pushing Docker images to ECR and deploying to ECS Services with blue/green deployments via CodeDeploy.

ECS Task Definitions & Service deployments
Fargate serverless container workloads
ECR private registry & image scanning
EKS managed Kubernetes clusters
Blue/green & canary deployment strategies

Amazon RDS & Aurora

Fully managed relational databases with automated backups, Multi-AZ failover, and read replicas. We migrate Oracle, SQL Server, MySQL, and PostgreSQL workloads to RDS or Aurora with zero-downtime strategies using DMS.

Multi-AZ standby & read replica setup
AWS DMS for heterogeneous migrations
Aurora Serverless v2 autoscaling
Parameter group tuning & performance insights
Automated snapshot & PITR recovery

AWS Lambda & Serverless

Event-driven serverless architectures using Lambda, API Gateway, Step Functions, SQS, SNS, and EventBridge. We design microservices that scale to zero and eliminate idle infrastructure costs.

Lambda functions in Python, Node.js, Java
API Gateway REST & HTTP APIs
Step Functions state machines
SQS/SNS event-driven pipelines
SAM & CDK infrastructure-as-code

VPC, CloudFront & Networking

Enterprise-grade network architecture with multi-AZ VPCs, Transit Gateway for hub-and-spoke connectivity, Direct Connect / VPN for hybrid workloads, and CloudFront CDN for global edge delivery.

Multi-AZ VPC with public/private subnets
Transit Gateway & VPN / Direct Connect
CloudFront distributions & WAF integration
Route 53 DNS with health checks
NLB / ALB with target group routing
