AWS Lambda Jobs

I am looking for a lead developer to architect and build a scalable "Sustainability-as-a-Service" platform. The core of the product is a high-performance API that will be integrated into the checkout flows of major e-commerce and delivery platforms to facilitate real-time environmental impact (tree planting) with every transaction. The core challenge is two-fold: High-Volume API Integration: We need a robust backend capable of handling thousands of concurrent requests from enterprise-level partners. The system must process transaction data, trigger fulfillment requests, and maintain 100% data integrity. The Transparency Layer: Our unique value proposition is verifiable proof. You must build a database and front-end dashboard that stores and serves geotagged data (GPS coordinat...

Project Overview This proof-of-concept will demonstrate a regulator-grade, fully secured VPC hosting a central authority and multiple financial-institution tenants, while automating supervision and compliance checks using native AWS services. Scope The environment will be logically segmented into public and private subnets for each participant. The central authority resides in its own network segment and can observe, query, and enforce policies across all other institutions without exposing sensitive resources publicly. Key Services AWS Lambda for event-driven oversight logic and scheduled compliance sweeps AWS RDS for the authoritative supervisory data store AWS S3 as the immutable audit and reporting repository Security & Compliance Networking, IAM, logging, encr...

Hope you are doing well today! I am working on a AWS Cloud based application, where I need some help in analyzing spot instance vs on-demand ec2 instances. Currently we are using on demand ec2 instances. We are looking to reduce the ec2 cost, so checking on spot instances usage, its working and the cost calculation for it. I want to know, more about spot instances, their usage, their cost effectiveness, and how it can be called/ used inside our lambdas. Is it something you can help me with?

I need help weaving Ujet seamlessly into an existing chat-bot so our customers get faster, smarter assistance without ever leaving the conversation. The immediate targets are: • Upgrading live-chat handling through Ujet’s real-time capabilities. • Letting the bot tap Ujet’s AI layer to recognise common queries and suggest accurate replies before a human agent steps in. Our bot already pulls answers from an internal knowledge base (built on standard REST endpoints), so the integration must respect that architecture—no data silos. I’ll share endpoint docs and authentication keys once we start. Success looks like this: a user launches chat, Ujet routes the session, the bot offers AI-driven suggestions, and the exchange is logged back to the knowledge bas...

I am rolling out a full CI/CD pipeline on AWS and want it driven by Spinnaker. The work starts with connecting Spinnaker to our existing Git repos, packaging a Java-based service, and automating its promotion through our Eaac environments via Jule. Key expectations • Spinnaker configured on AWS with the right roles, accounts, and artifact stores so a commit can move from build to deploy without manual steps. • Pipeline stages that compile and unit-test the Java code, create versioned artifacts, run automated checks, and push straight to production once everything passes—with easy rollback built-in. • Clean, reusable templates so additional Java services can be onboarded quickly. • Clear hand-off documentation and a brief walk-through so the team can ope...

I need a clean, self-contained AWS sandbox that lets me bring external freelancers on board without touching production. The environment has to spin up with repeatable infrastructure code (CloudFormation preferred) and include the following building blocks: • EC2 instances • S3 buckets • RDS databases • Lambda with API Gateway endpoints • DynamoDB tables • ECR repositories tied into CodeBuild pipelines • Centralised CloudWatch Logs I’ll use this space strictly for managing freelancer workstreams, so every resource must sit behind tightly-scoped IAM roles and clearly labelled cost tags. Please deliver the templates (or stacks) ready to launch, a short README on how to deploy them, and a quick sanity test that proves each service is reac...

I need test cases for our Python lambda logic, specifically around the application registration for the IELTS exam. Requirements: - Cover functionality and error handling - Validate application registration process - Handle invalid input data - Manage database connection issues - Address API call failures Ideal Skills: - Proficiency in Python - Experience with AWS Lambda - Strong background in writing test cases - Familiarity with error handling and input validation

I’m expanding a cloud-native platform and need a hands-on Java specialist who can comfortably navigate our AWS stack while lending light support to the React front-end and a couple of Python utilities. Core work will revolve around building and optimising Java microservices that run in Lambda, interact with API Gateway, DynamoDB, and S3, and expose clean, well-tested endpoints to the React client. Alongside the usual feature work, we’re beginning to weave in basic AI functionality—simple model inference, small-scale data pipelines, and a bit of NLP where it makes sense—so any prior experience wiring up popular ML frameworks or hosted AI APIs will put you ahead of the curve. If you decide to apply, point me to past projects that show: • Solid Java engineering ...

I am rolling out a new environment that spans Terraform-managed infrastructure, automated Github Actions workflows, and integrations with Snowflake and Mulesoft. The area where I need the most hands-on help is AWS—specifically provisioning, securing, and optimising EC2 instances, S3 storage buckets, and a series of serverless Lambda functions that glue everything together. Here’s the flow I’m targeting: • Terraform drives all resource creation so our stacks remain fully reproducible. • Github Actions handles CI/CD, triggering Terraform plans/applies and Lambda deployments on every merge. • Data exchanged between Snowflake and our micro-services is exposed through Mulesoft APIs running behind AWS resources. What I need from you: a clean, modular Te...

I’m ready to give Stella Vanancia a cohesive online footprint and need one partner to deliver everything in sync: • an informational/blog website, • a companion mobile app, and • a lightweight desktop software application. Purpose The entire suite will be content-driven—think timely articles, updates, and resources, not e-commerce. Consistency in look, feel, and navigation across all three platforms is essential. Core requirements • A CMS that lets me publish, tag, and manage posts easily. • At minimum, a Contact page with a working form; I’m open to your ideas for a Home, About, or any other supportive pages. • Clean, responsive UI, fast load times, and accessibility best practices. • One shared backend or API so web...

I want to add three solid, portfolio-ready papers to my personal body of work and I need an expert writer-researcher to produce them for me. Each paper must be: • 8 pages (≈ 5 000 words) • fully formatted in IEEE style and delivered as clean, compilable LaTeX • accompanied by the final PDF Scope for the three papers 1. AWS services and cloud-native architecture—cover core building blocks such as VPC, IAM, S3, Lambda, and how they interoperate in production-grade designs. 2. Data Engineering methodologies—drill into ETL processes and modern data-pipeline patterns on AWS (Glue, Step Functions, Kinesis, etc.) with diagrams and code snippets where helpful. 3. AI/ML algorithms and applications—tie in SageMaker, feature engineering, and model de...

My web application is production-ready, the code sits in Git, but it still lives only on my laptop. I want it running reliably in AWS right away. Here’s the current plan: store static assets in S3 and integrate clinical data through AWS HealthLake; the core app can run on whichever AWS compute option you recommend as the fastest path to a live build. I’m open to EC2, Elastic Beanstalk, or even a container service if that shortens setup time, as long as the end result is secure, scalable, and easy for me to maintain. I need you to: • stand up the full AWS infrastructure (VPC, subnets, security groups, IAM roles, S3 buckets, HealthLake workspace, and chosen compute layer) • deploy the existing code and verify the app functions exactly as it does locally &bul...
