1-on-1 Coaching in Engineering Productivity, Leadership, Mindset & Conflict ResolutionTechnology Mentoring & Focused Pair ProgrammingConsultant for Early-stage Tech Startups and Scale-ups

Serving the CTO and his product engineering teams to improve vertical product integration, capacity accuracy and craftsmanship practices particularly automated testing by leading a growth-centric initiative for 9 months.Our goal was to reduce time to market on new product features while improving maintainability of core legacy systems by introducing better triage strategies and quality-creating DevOps competencies within the team.Coached key engineers on adopting and enabling testing pipelines into their regular workflows. Performed a Project Rescue on an uncertain affecting a large-volume data flows by introducing ensemble programming and paired-TDD practices.Reduced feature abandonment waste caused by stale pull requests by introducing high-trust pairing and collaboration methods to reduce lead times on process hand-overs and PR pickup. Expanded this initiative into introducing DORA metrics for the main pipeline.Improved well being and reduced isolation by mentoring communication and negotiation skills with the help of qualitative surveys and strategic capacity to complement existing Scrum pipeline and stakeholder roadmap planning.

Built the production version of the Dota 2 Tournaments tech as a hands-on tech lead. I mentored new hires onto our stack and improved our reliability and delivery speeds by introducing TDD and QA automation principles for Dota 2 tournaments.Built the prototype for PUBG Tournaments, which later became PUBG Bounty Hunts. As a hands-on Architect on the team I was responsible for negotiating with and integrating into several different PUBG-related APIs and services that fed our systems with a stream of telemetry and game data.The reliability and scaling challenges allowed me to introduce the following solutions:• Developed an internal Diagnostics tool (termed "Doctor") that provided live auto-repair and notification functionality for on-call personnel• Developed and provided custom infrastructure for Microservice integration with Docker and AWS• Handled automated testing with multi-user socket streams to simulate Dota2 and Pubg scenarios• Compartmentalised architecture artefacts via SDKs, internal documentation, and ownership boundaries as the number of microservices grew beyond 50+ from a single monolith• Modernized the tech stack to provide better monitoring, telemetry and scaling options by introducing message queues, write-through caching, CQRS and socket load balancing.Introduced ELO-based ladders and rating systems into the matchmaking systems for Firstblood's Dota 2 challenges.Tech Exposure: node.js, Typescript, Angular, RxJs, MongoDB, Redis, RSMQ, RabbitMQ, traefik, Docker, Kubernetes, Auth0, JWT, Ethereum Blockchain, Smart Contracts, web sockets, sockets.io, Jest, Jenkins, Bash, PostgreSQL

Modernized and scaled the subscription automation process used by Flaviar to pair spirits flights with monthly package shipments by separating it from the e-commerce platform and integrating with Stripe so that it could handle 4000/day order processings per day rather than doing it semi-manually.Developed and Integrated an in-house Business Intelligence tool for internal strategy decisions by aggregating data from subscriptions, marketing, PLG, warehousing & logistics and e-commerce related data platforms and merging it into a single data warehouse using ETL and PostgreSQL.Built a prototype for flavour-pairings and similarity rankings for Spirits products (E-commerce, exploration, marketing).Tech exposure: PHP, PostgreSQL, MySQL, MongoDB, Javascript, Typescript, Stripe, Klarna, Docker, XUnit

Lead the architecture and integration effort to integrate with the Facebook Ad Platform as a Certified Partner. Using domain-driven design and clean architecture principles I maintained the bidirectional live communication for Ad Creation and Conversion Metrics reporting connecting both platforms.Optimized serving speed of internal on-site CDNs by optimizing and simplifying their architecture so that they could serve and handle media and telemetry requests beyond 10000 requests/min through the Ad platform in over 20 different geographic regions, optimized for desktop and mobile.Improved deployment practices by minimizing build and testing time with the introduction of CI tools and webpack into a mostly jQuery-oriented tech stack. Supported the modernization of this tech stack, later introducing reactive tooling and React itself onto the main AdPlatform interface.Architected and modernized legacy systems inherited from acqui-hires, improving their life span and reducing their operating costs by separating them by various platform-related concerns and creating an infrastructure for parallel deployments and hosted backend monoliths. This infrastructure later became a multi-server modular, distributed monolith.Researched and developed the first in-content ad tech used by Httpool to serve banner, text and later video ads throughout its international network.Built the prototype and production version of Engagement Ads for international Httpool clients.Tech exposure: PHP, Symfony, Java, React, Angular, HTML5, HBase, hadoop, MongoDB, Redis, AppNexus, RxJs, React, NgRx, PostreSQL, MariaDB, webpack, node.js

Provided technical expertise for pre-seed start-ups by developing high-fidelity prototypes for product-market fit research. Notable projects I have worked on:• DenTech, meditech for dentist appointments and scheduling• Linqia, social media platform for organic influencer advertising• Spedire, shipment platform for C2C and B2B deliveries• Zoomvino, yellow pages for European wineriesLead a team of engineers and designers for E-commerce projects, including Mommylike and E-vino.Introduced and presented topics of github workflows, automated testing, TDD and CI with Jenkins onto company-wide tech talks.Skills: PHP, Java, Ruby, Python, Prestashop, Drupal, Jenkins, XUnit, nginx, UPS, Zend Framework
