Some of our work


Blockchain



Extensive expertise in deploying, customizing and optimizing the OPStack to improve performance, scalability and reliability to meet specific use-case requirements set by our clients.


We architect, deploy and operate a fully bare-metal blockchain infrastructure, ensuring 99.99% uptime for Staking(vouch, dirk, mev-boost), Relays, Geth, Reth, Lighthouse, Prysm, Nimbus, dApps, RPC proxy, OPStack, EigenDA and more in k8s environment. Our e2e setup includes everything required to initialize, manage and scale blockchain infrastructure, covering monitoring, alerting, performance and security to deliver a robust, high-performance environment for mission-critical applications.


A pre-confirmation system enabling secure and low-latency transaction pre-confirmations without requiring restaking or ePBS was architected, implemented and deployed. It optimizes gas efficiency, transaction ordering and block space utilization while integrating seamlessly with Ethereum’s existing infrastructure. The system enhances predictability for users and profitability for validators.


We have deep expertise in Flashbots' mev-boost-relay, actively managing and modifying it to expand functionality and introduce new features. Alongside this, we have built an alternative relay designed to simplify deployment, reduce resource usage and streamline operations, making it easier to run and maintain.


RPC proxy designed for high performance connections to Ethereum nodes, enabling secure and efficient blockchain interactions with built-in failover mechanisms, a custom Ethereum node registry and intelligent load distribution, ensuring RPC requests are dynamically balanced to prevent overloading any single node while maximizing reliability and responsiveness.


Block builder designed to maximize MEV extraction per block by constructing blocks with optimal efficiency, supporting advanced value extraction strategies from private pools and the global mempool. The builder enhances transaction inclusion and ordering, reducing frontrunning risks and boosting MEV rewards for validators.


A xk6 extension that focuses on testing and validating Ethereum L1 and L2 rollups under realistic workloads. This allows us to simulate on-chain activity, benchmark performance and identify system bottlenecks before they reach production.

Fintech



We have experience building robust data pipelines to deliver accurate, high volume ESG insights at scale. The system ingests and processes raw data from multiple third party sources to generate accurate, high quality insights on corporate sustainability. Our focus was on data reliability, scale and efficient delivery.


Built as part of a cross functional team, we worked on a merchant payment platform that was designed for secure and scalable transaction processing and was running in production inside 4 months since inception.

AdTech



Revived and evolved a struggling dynamic ad platform into the company’s core monetization engine. Strategic improvements in architecture, build process and ad formats led to faster deployment cycles, better performance and a significant increase in revenue. The platform supported new markets, improved CTRs and reduced cloud costs, all while enabling faster experimentation and delivery of new dynamic ad formats.


Suite of tools for validating and previewing creative assets across teams and platforms. This included automated validation and a web preview interface integrated with internal workflows.


Integrated the IAB Open Measurement standards into custom MRAID bridge that was used across multiple platforms (iOS, Android, Windows).


Data rich analytics dashboards capable of rendering millions of data points in real time. The solution included a custom filter query engine for advanced data exploration and a reusable front end component library that now serves as a foundation for multiple client facing applications.


End-to-end ad testing system to ensure campaign integrity and creative reliability at scale. The platform reduced broken campaigns and dramatically improved the quality and trustworthiness of ad delivery pipelines.

eCommerce



Application that enabled merchants to mint and sell NFTs directly through their Shopify stores. The application provided full control over the NFT creation and sales process. A lightweight, cost efficient infrastructure was designed, along with full monitoring and observability to ensure reliability in production.
