Software Engineering Events in Bucharest

This is the widest category on Brainberg, because software engineering itself spans a huge range of events: language user groups (Python, Rust, Go, TypeScript, Kotlin, Elixir, Ruby, Zig), framework communities (React, Svelte, Next.js, Vue, Laravel, Django, NixOS), backend architecture tracks, testing and QA tracks (ISTQB certification courses, mutation testing, test-automation workshops), refactoring and DDD circles, hackathons, and the long tail of "thoughtful engineering" meetups that don't fit neatly under any specific stack.

This page narrows the Bucharest calendar to Software Engineering events. It's a subset of Romania's wider tech-event schedule, useful when you want something specific to go to in the city this month.

Navigating Frontier RL for LLMs: Moving Beyond the Narrow Regime

Bucharest, 🇷🇴 Romania

Bucharest Deep Learning is back with another exciting session! Join us for a deep dive into the realities of scaling Reinforcement Learning for Large Language Models alongside Teodor Poncu, Member of Engineering (Reinforcement Learning) @ poolside, exploring what happens when we push beyond standard training constraints.

The Talk: Navigating Frontier RL: Moving Beyond the Narrow Regime

Current work on RL for LLMs—encompassing algorithms like PPO, GRPO, RLVR, and DAPO—is largely drawn from a narrow, comfortable regime. This typically involves a single domain, small to mid-size models, synchronous loops, clean rewards, and a limited number of steps. But what happens when we scale up?

Frontier RL departs from this standard environment along several critical axes simultaneously, and this presentation explores exactly where those departures actually matter. The talk will cover four key areas of frontier RL: the infrastructure challenges where rollouts dominate iteration time and demand staleness tolerance; the complexities of multi-domain training where heterogeneous tasks make naive batching untenable; the formulation of RL scaling laws as a function of compute; and finally, how to handle the numerical instabilities driven by modern architectures like Mixture of Experts (MoEs).

PocketBytes - Firing AWS Firehose: Moving to a Stateful Lambda

Bucharest, 🇷🇴 Romania

Join us for an expert case study on how to. replace AWS Firehose, a Managed Cloud Service, with a Stateful Lambda (Without Losing a Record)

Location: In The Pocket Bucharest - Tudor Arghezi 21, H building, 4th floor

What we'll discuss:
Managed services are convenient until the bill arrives. In this case study, we replaced AWS Kinesis Firehose with a purpose-built serverless consumer for a client streaming millions of IoT records per minute into their datalake — taking on full ownership of batching, buffering, file layout, and durability in exchange for a fraction of the cost.

The catch? We built it on AWS Lambda, which is stateless by design. We'll walk through how we made it stateful using Kinesis tumbling windows, how an S3 multipart-upload state machine is carried across invocations, the retry semantics that guarantee zero data loss, and the trade-offs we deliberately made — including the ones where doing the "right" thing would have quietly made things worse.

If you've ever wondered what's actually happening inside a managed streaming service, or what it takes to build one yourself, this one's for you.

Agenda:

  • 18:30 - 19:00 - Welcome
  • 19:00 - 19:05 - In The Pocket Intro by Adrian Petrescu
  • 19:05 - 20:00 - Firing AWS Firehose: Moving to a Stateful Lambda by Alexandru Gheorghita

Alex is a passionate Software Engineer specializing in Cloud and AI Engineering. With a strong foundation in designing scalable cloud architectures using AWS and Terraform, alongside full-stack development in Go, Python, and TypeScript, he thrives on turning complex technical challenges into intelligent solutions. Beyond the code, he is deeply committed to the tech community - whether mentoring students, leading technical workshops, or championing a culture of continuous learning and knowledge-sharing.

  • 20:00 - 22:00 - Networking
