I worked here as Senior Software Engineer, as part of a brilliant, small team. We all had responsibility for the whole codebase, including the customer-facing website, internal tools for our agents to facilitate the lettings, ETL and real-time data processing pipeline for our business intelligence unit, and DevOps / Continuous Integration.

Single-handedly designed, architected and coded the entire Backend infrastructure, with an obssessive focus on reliability, performance and scalability.

After the initial development phase, worked extensively on performance, through stress tests and profiling, reaching a sustained throughput high enough to serve 4 million daily active users, with only a single medium-sized PostgreSQL instance, and a response time in production consistently under 20ms (95% percentile).

Features of the backend system include: Messaging and conversation history; Multi-device synchronization; Phonebook processing and matching to find friends; Photo uploading and processing; Music processing: ingestion from music labels (DDEX Standard), automated editing and recompressing; Internal admin tools to manage playlists; Fully-featured Search including searching on lyrics, tags and metadata.

December 2013 - November 2014 Lead Ruby on Rails and JavaScript Developer at Gallant Capital Markets

Worked as a contractor for a global leader in online trading that specializes in Forex, developing new features for an internal management tool used to keep track of all of Gallant's clients, their finances and their trading.

Took requirements from the CTO, did the whole analysis and developed a significant new feature through to completion and deployment in production. This feature impacted multiple moving parts in the existing system and implied rewriting a considerable part of it.

Also worked extensively on performance, reducing batch process execution from hours to under a minute, and enormously reducing CPU load on the trading servers.

This system was originally developed by me several years ago, on a previous contract with this client, and I was requested to return to work with them for this specific development.

Features of the system include: Whitelabeling, Multi-tier affiliate system and commission distribution, full Integration with MetaQuotes Metatrader, Salesforce, and a bespoke VPS provisioning system.

"Daniel is a rare beast, understanding the big picture, technically and commercially, whilst being able to identify and define the minuscule detail that will make the wider vision achievable. Equally adept at designing features and writing complex code, he works at a pace unrivalled. Add to that a great sense of humour and deep knowledge on the weird and the wonderful, he was a great colleague and is now a good friend."

Julian Johnson - Founder and CEO, Watu
About my work at Watu, a startup selling a SaaS management tool for staffing agencies.

"As a financial solution provider we outsource a great deal of our development work.

Our relationship with Daniel Magliola is without a doubt the best outsourcing experience we have ever had.

Daniel, unlike other providers, will take the time to review and analyse each project with us. Often pointing out issues and considerations that would have cost us a lot more had they come up during the development.

He is dedicated to meeting his deadlines and makes himself available at all hours to support and manage any unexpected problem that arise. I would recommend Daniel to any company in search of a reliable, long term software development partner."
