2 AWS certifications: AWS Solutions Architect Associate · AWS Cloud Practitioner

• 15+Serverless applications shipped
• 100%Test coverage maintained
• 2+Years of experience
• 20+Technologies

• Retrieval-Augmented Generation

  Described competency

  Grounding language-model responses in external knowledge by retrieving relevant context at query time and feeding it into the prompt, reducing hallucination and keeping answers current with authoritative sources.

• LLM Applications

  Described competency

  Designing production application flows around large language models — prompt design, streaming responses, context-window management, structured output, and guardrails — built on the same TypeScript and serverless foundations used for the platform work at Amazon.

• Agents

  Described competency

  Composing autonomous and semi-autonomous agent workflows that plan, call tools, and iterate toward a goal, with explicit state, stopping conditions, and human-in-the-loop checkpoints for reliability.

• Retrieval & Embedding Pipelines

  Described competency

  Building ingestion and embedding pipelines that chunk source content, generate vector embeddings, and index them for semantic retrieval — a natural extension of the serverless data-automation pipelines already shipped on AWS Lambda and EventBridge.

• Tool Calling

  Described competency

  Exposing typed functions and external APIs to a language model so it can invoke them with validated arguments, mapping model intents onto real backend actions with the same type-safety discipline used for tRPC APIs.

• Evaluation Pipelines

  Described competency

  Measuring model and application quality through automated evaluation harnesses — golden datasets, regression checks, and scoring metrics — applying the 100% test-coverage discipline maintained on the Quality Management Platform to non-deterministic systems.

• System Design

  Designing full-stack systems end to end — from edge authentication and type-safe APIs to data modeling and analytics — for the Quality Management Platform serving managers across North American fulfillment centers.

  • Designed a TypeScript monorepo (React 19, tRPC, AWS CDK) with a serverless API layer and CDN-based authentication.
  • Implemented edge-level authentication, role-based access control, and real-time user monitoring.
  • Built analytics dashboards with multi-location filtering and manager-level data aggregation.

  • AWS Lambda
  • CloudFront
  • DynamoDB

• Scalability

  Building event-driven, serverless workloads that scale to production traffic across multiple locations without managing servers.

  • Developed 15+ serverless data-automation tools processing operational data from S3 and internal APIs.
  • Delivered real-time alerts via SES, SNS, and Slack to operations teams.
  • Launched the platform MVP at a pilot location and expanded toward 8+ additional fulfillment centers.

  • AWS Lambda
  • EventBridge
  • SES
  • SNS
  • S3

• Cloud Architecture

  Architecting and deploying a multi-region web platform entirely as infrastructure-as-code, reproducible through AWS CDK with automated CI/CD.

  • Provisioned a multi-region footprint through AWS CDK infrastructure as code.
  • Owned the full lifecycle from architecture design through CI/CD deployment and production monitoring.
  • Configured CDN delivery, edge authentication, and observability for production workloads.

  • CDK
  • CloudFront
  • CloudWatch
  • Route 53
  • WAF

• AWS Services

  Hands-on depth across the AWS serverless and infrastructure stack used to run the platform and data-automation tools in production.

  • Compute and APIs on AWS Lambda with tRPC and DynamoDB persistence.
  • Messaging and notifications through EventBridge, SES, and SNS.
  • Edge delivery and security via CloudFront, WAF, and Route 53, with monitoring through CloudWatch and RUM.

  • DynamoDB
  • S3

  • CloudWatch
  • RUM
  • WAF
  • Route 53

• Backend Engineering

  Writing type-safe, well-tested backend services in TypeScript and Python, owning the software lifecycle from requirements through production monitoring.

  • Built type-safe tRPC APIs backed by DynamoDB with role-based access control.
  • Maintained 100% test coverage across 6 packages using Vitest, ESLint, and snapshot testing.
  • Automated CI/CD pipelines for repeatable, infrastructure-as-code deployments.

  • AWS Lambda
  • DynamoDB
