Durable Lambda Functions + ECS Managed Instances + Bedrock for perfect podcast transcriptions
I co-host AWS Bites with Eoin Shanaghy. The show has passed 150 episodes, and since it is a side project alongside a full-time job, the production workflow has to be efficient. A few years ago Eoin and I built an automated system to transcribe each episode and generate subtitles for YouTube and the website. That system became Podwhisperer, an open-source pipeline that anyone can deploy in their own AWS account to automate podcast transcription. Three years is a long time in the AWS world. Better speech tooling showed up, new ways to run GPU workloads became practical, and durable orchestration in Lambda got a lot more interesting. So we rebuilt the project as podwhisperer v2: a serverless transcription pipeline optimized for podcasts, with GPU-accelerated transcription, speaker diarization, and an optional refinement step powered by Amazon Bedrock. v2 also produces captions in VTT, SRT, and JSON — including word-level timing — so the output can be used directly across platforms without extra manual work. This talk is a practical case study of the v2 architecture and the trade-offs behind it. The workflow is orchestrated with a Durable Lambda Function, so long-running jobs survive Lambda timeouts thanks to automatic checkpointing. GPU work runs in a container on Amazon ECS Managed Instances, which provisions CUDA-capable capacity on demand and shuts it down when...

AWS Lambda: Rust to the rescue!
Rust is taking the software engineering world by storm, but how does it affect serverless? In AWS it’s not even a supported runtime, so how can we even use it… and should we even try to do that? Spoiler: yes we should and it’s actually quite easy to get started with it… and the benefits are amazing!

Static APIs, the Unsung Heroes - Coderful Backend 2025
Are you familiar with static websites, often referred to as the "Jamstack"? The concept is straightforward: generate HTML, CSS, JavaScript, fonts, images, and other assets at build time and publish them on a CDN. The result? Incredibly fast websites with no servers to manage and extremely low costs! Now, imagine being able to apply the same approach to your APIs, using only pre-generated JSON files hosted on platforms like GitHub Pages or Netlify. No servers, no databases: just instant responses accelerated by a global CDN. And the best part is that even for features like full-text search, there are entirely client-side static solutions available, making them virtually free! In this talk, we will delve into how static APIs work, exploring their advantages, limitations, and practical use cases. I will show you concrete examples and provide reusable templates to immediately put these techniques into practice.

Managing AWS accounts like a PRO
Using multiple AWS accounts is a best practice that can help you isolate and manage business applications and data. If you have looked at the AWS Well-Architected Framework you might have seen that having multiple accounts for an organisation can help achieve operational excellence, security, reliability, and even cost optimisation. Starting with a good multi-account foundation is something that will enforce many best practices from day 0, like, for example, not having long-lived credentials on developers’ machines. And the benefits just get greater as the company grows and the level of cloud adoption increases. It’s a practice that scales well from 1 developer to thousands of developers! In this talk, I will show you how to leverage services such as AWS IAM Identity Center, AWS Organizations, and tools such as Granted and OrgFormation to manage multiple accounts confidently and consistently.

Serverless Rust su AWS Lambda "for fun and profit" - Codemotion Workshop Fest 2024
Esploriamo l’incrocio tra la flessibilitá di AWS Lambda e le performance di Rust, scoprendo perché Rust è la scelta perfetta per dominare questo ambiente innovativo e dinamico. Durante la sessione scriveremo la prima funzione Lambda “Hello World” utilizzando Rust, scopriremo poi come testarla localmente e come rilasciarla in produzione. Esploreremo poi un caso d’uso piú concreto sviluppando un’API in Rust da rilasciare con SAM per gestire la definizione dell’infrastruttura secondo la metodologia IaC (Infrastructure as Code). Questo workshop, oltre alle conoscenze pratiche, darà l’ispirazione per trasformare il modo di sviluppare applicazioni puntando a pratiche e tecnologie innovative come Serverless e Rust.

An intro to `nom`, parsing made easy for Rustaceans - Rust Dublin
In this talk we will give you a pragmatic introduction to `nom` , a famous Rust parser combinator crate, which, in other words, is a tool that makes it easy to create parsers even for more advanced use cases. We will start by showcasing common suboptimal ways to do parsing including string splitting and using regexes. Then we will introduce nom and the main concepts it builds on, including its most commonly used functions. Finally, we will present several examples, from a few simple ones to building an entire parser for RESP, the Redis Serialization Protocol. If we do a good job, you'll probably forget about regex :)

Everything I know about S3 pre-signed URLs - AWS ComSum Manchester 2023
Almost every web application at some point needs a way to upload or download files… and no one seems to enjoy building reliable and scalable upload/download servers… and for good reasons too! In fact, you’ll probably need to manage long-running connections and handle files that can be quite large (i.e videos). If you are running a fully serverless backend using API Gateway and Lambda, you probably know that you are limited in terms of payload size and execution time, so things get even more complicated there. In all these cases you should consider offloading this problem to S3 by using S3 pre-signed URLs. Pre-signed URLs are a fantastic tool to handle file download and upload directly in S3 in a managed and scalable fashion. But all that glitters is not gold and S3 pre-signed URLs come with quite a few gotchas… So in this talk, we will explore some use cases, see some potential implementations of S3 pre-signed URLs and uncover some of the gotchas that I discovered while using them. By the end of this talk, you should know exactly when to use pre-signed URLs and how to avoid most of the many mistakes I made with them!

Did you know JavaScript has iterators? - Node.js Conference Italy
How many ways do you know to do iteration with JavaScript and Node.js? While, for loop, for…in, for..of, .map(), .forEach(), streams, iterators, etc! Yes, there are a lot of ways! But did you know that JavaScript has iteration protocols to standardise synchronous and even asynchronous iteration? In this workshop we will learn about these protocols and discover how to build iterators and iterable objects, both synchronous and asynchronous. We will learn about some common use cases for these protocols, explore generators and async generators (great tools for iteration) and finally discuss some hot tips, common pitfalls, and some (more or less successful) wild ideas!
