Migrating a Fintech Analytics Stack to Open Source - Kshitish Deshpande - FOSS Meetup Pune

Kshitish Deshpande

Software Engineer @One2N

Migrating a fintech analytics stack off fully managed AWS services can save serious money, but only if you do it without breaking business reporting or slowing teams down. In this FOSS Meetup Pune talk, Kshitish Deshpande (Software Engineer at One2N) walks through how his team helped a cross‑border B2B fintech processing 50–70M USD in daily transactions move from an all‑AWS analytics pipeline (Postgres, DMS, Glue, Athena, QuickSight) to a fully self‑hosted open‑source stack on ClickHouse, Pebble, Prefect, and Apache Superset. You’ll see how they planned the migration, ran both pipelines in parallel, and gave business teams the same dashboards while cutting infra costs dramatically.

Kubernetes for Hybrid Cloud Environments - Harshwardhan Mehrotra - #60 Kubernetes Pune Meetup

Harshwardhan Mehrotra

SRE @One2N

Scaling Kubernetes workloads across 40+ data centers is hard – especially when you must meet strict data residency and latency requirements while still leveraging the public cloud. In this talk from the Kubernetes Pune Meetup, Harshwardhan Mehrotra (Site Reliability Engineer at One2N) walks through how his team designed and operated an EKS hybrid setup for a large betting platform with data centers across the US, UK, and Europe. You’ll see how they connected on‑prem worker nodes to an AWS EKS control plane, handled networking at scale, and kept the developer experience close to a “normal” EKS cluster. What you’ll learn: - Why EKS hybrid was chosen over fully on‑prem or fully cloud, and how regulatory and latency constraints shaped the architecture. - How to design pod vs node networking, routable vs non‑routable pod networks, and when to bring in BGP. - How to connect 40+ data centers to AWS using Direct Connect / site‑to‑site VPN and Cilium/Calico CNIs. - How to expose apps using F5 and Istio/NGINX ingress when ALB is not an option. - Real‑world issues with DNS (CoreDNS, Route 53 limits, node‑local DNS) and traffic distribution, plus how they fixed them. - Lessons on egress control, firewall bottlenecks, add‑on placement (Argo CD, KEDA, Prometheus, etc.), and building repeatable playbooks for on‑prem nodes. - This talk is ideal for platform engineers, SREs, and architects running Kubernetes across data centers and cloud, or evaluating EKS hybrid for regulated workloads.

Solving Synthetic Data generation using LLMs | mitramadal.ai EP2 - 2026

Chinmay Naik

CEO @One2N

In this talk at mitramandal.ai EP2, Chinmay Naik (Founder & CEO, One2N) walks through how One2N solved the problem of synthetic data generation using LLMs - covering the real-world use cases that drove it, why anonymization falls short, and how they built a tool that uses LLMs for schema generation and deterministic faker-based data generation.

.zshrc tmuxinator tease | Command Line Heroes EP3 - Bengaluru

Saurabh Hirani

Principal SRE @One2N

Command Line Heroes is a meetup series for developers, SREs, and terminal nerds who love living inside the shell. ​In episode 3 from Bengaluru, Saurabh Hirani (Principal SRE at One2N) walks through a real-world debugging story where Kiro CLI quietly breaks his beloved Tmuxinator setup. ​ This talk is a deep dive into how a “simple” autocomplete feature ended up sitting between Ghostty/VS Code, tmux, and zsh, and why things started to go weird: tmux panes showed commands but refused to execute them, shell startup got slower, and mysterious processes began to appear. ​ Along the way, Saurabh uses LLMs, exec, and process inspection to peel back the layers and explain what’s really happening inside your terminal sessions. CLI Heroes Ep3 was an in person meetup held on 31st Jan 2026, thanks to Smarsh Inc for providing the venue, this is just a small snippet of the things that happened at the meetup.

Optimizing Kafka Performance with Automated Benchmarks

Kalpesh Deo

Lead Software Engineer @One2N

Curious about getting the best performance out of your Kafka setup? In this talk, Kalpesh from One2N walks us through his experience of benchmarking Kafka producers using the kafka-producer-perf-test.sh tool. By experimenting with settings like compression.type, linger.ms, and batch.size, Kalpesh’s team managed to boost throughput by 245%, cut down latency by 90%, and save 89% on storage all by fine-tuning some key configurations. What you’ll learn: How tuning Kafka producer settings impacts real throughput, latency, and storage. The power of scripting to automate and simplify performance benchmarking. Techniques to interpret and apply benchmarking results for your own Kafka deployment. Kalpesh’s 16+ years in backend, cloud, and distributed engineering shine through as he delivers actionable insights for engineers seeking to fine-tune their data pipelines

A beginners guide to understand Kubernetes using Restaurant Analogy | DevOpsDays Kerala 2024

Chinmay Naik

CEO @One2N

Kubernetes is 10+ years old, yet one of the most common complaints about it is that it’s much harder for newcomers to learn. This talk aims to fix this. If we can make Kubernetes approachable for developers, we can have a massive positive impact on its adoption.
