His strongest areas are \.NET, Azure, SQL Server, Angular, ETL architecture, financial systems, and the modernization of legacy applications into modular cloud\-native services\. Aleksej applies a “Build for N, never for 1” philosophy: components are designed from the outset to support multiple users, data sources, and workflows rather than a single use case\. At Houlihan Lokey, he was the sole architect and developer of a JSON\-configured Azure ETL framework that allows pipelines to be added or changed with zero redeployment and to go live in minutes\. He also contributed to rewriting a portfolio\-valuation platform on Azure and built its ExcelDNA add\-in, reducing large\-model load times from more than an hour to 1–2 minutes\. Aleksej has also delivered serverless AWS applications, reusable \.NET data\-repair tooling, financial\-services ETL and validation systems, and full\-stack Angular projects\. He holds a BS in Computer Science and Mathematics from Boston College and was a Division I varsity swim\-team captain\. ## Services - Microsoft Azure - Git - SQL - Search Engine Optimization \(SEO\) - \.NET Framework - User Interface Design - Data Visualization - Sales - Google Analytics - Google Ads - Facebook Ads - Customer Service - Web Development - Software Development - Applied Mathematics - Object\-Oriented Programming \(OOP\) - Mathematics - Algorithms - Spanish - English - Verilog - C \(Programming Language\) - Adobe Photoshop - Adobe Illustrator - Microsoft Office - JavaScript - Cascading Style Sheets \(CSS\) - HTML - Python \(Programming Language\) - Java ## Highlights - Solely architected and developed a cloud\-native \.NET ETL framework on Azure, using JSON configurations in Blob Storage to add or modify pipelines with zero redeployment\. - Built a reusable ETL node library supporting SFTP, SQL, Snowflake, Blob Storage, local files, CSV, email, transformations, and mid\-pipeline normalization it supports unlimited pipelines and unlimited sequential or parallel nodes per pipeline\. - Enabled new Azure ETL pipelines to go live in minutes\. - Played a vital role in rewriting a legacy portfolio\-valuation service on Azure App Service, Azure Data Factory, API Management, and Application Insights\. - Implemented multi\-vendor pricing ingestion, cross\-source SQL normalization, and \.NET HTTPS APIs behind Azure API Management for portfolio valuation\. - Solely built an ExcelDNA add\-in with Entra ID authentication, automatic remote updates, and parallel API calls\. - Reduced large Excel\-model load times from more than one hour to 1–2 minutes through Excel range\-logic and asynchronous\-processing optimization\. - Refactored and secured a legacy \.NET and SQL Server SOAP application in an on\-premises DMZ, extending its production lifespan while an Azure replacement was developed\. - Reduced Excel\-based financial\-analysis report generation by approximately 97%, from 2–3 hours to under five minutes, in an Angular and Python Flask application\. - Established a complete QA process, onboarded a QA engineer, created automated Postman API\-test collections, and built Excel edge\-case test worksheets\. - Designed and developed a high\-availability, scalable B2B PDF\-generation application using Angular, \.NET Core, and AWS Lambda, API Gateway, SQS with DLQ, RDS, S3, CloudFront, and CloudWatch\. - Built an Angular GEDCOM genealogy viewer with dynamically rendered family trees, profile pages, searchable archives, and gallery, calendar, map, and data\-grid integrations\. - Deployed the Family Tree Viewer with GitHub Actions CI/CD on AWS S3, Lambda, and CloudFront, with lazy loading, responsive design, and mobile\-friendly behavior\. - Developed a responsive Angular architecture\-firm template with modular components, dynamic forms, and reusable UI elements\. - Created and distributed a reusable NuGet package for detecting and reconstructing missing Entity Framework record versions\. - Designed a documented, reproducible Docker home\-server stack with Plex, AdGuard Home, Paperless\-ngx, Portainer, Speedtest Tracker, Uptime Kuma, and redundant OneDrive synchronization\. - Developed an audit\-trail algorithm and dynamic Entity Framework context to reconstruct lost or inconsistent versioned database records at Accordia Group LLC\. - Implemented NLog HTTP request logging and custom Kestrel middleware across Accordia Group LLC back\-end services\. - Redesigned data schemas and Entity Framework models for Interest Rate Swaps and FX Forwards, supporting dynamic calculations of market value, cost, fees, and FX rates\. - Implemented validation for Futures, Options, Equities, Drawdown Funds, Cash, and associated orders, allocations, and fills\. - Streamlined ETL for FIX messages, end\-of\-day broker reporting, cash reconciliation, and 13F, 13G, and 13H regulatory reports using FTP/SFTP and SQL/JSON validation\. - Co\-founded and operated Skeleton Shack, overseeing creative direction, e\-commerce and web development, production, marketing, client engagement, and LLC financial and compliance operations\. - Provided professional\-studio videography as a production assistant for Gohar’s Guide on YouTube videos that reached millions of views\. - Earned a BS in Computer Science and Mathematics from Boston College in 2023 and served as a Division I varsity swim\-team captain\. ## Experience - **Software Engineer at Houlihan Lokey** (2025\-06\-01–2026\-05\-01) — Sole architect and developer of a cloud\-native \.NET ETL framework on Azure, driven by JSON pipeline configurations in Blob Storage with zero redeployment to add or modify pipelines\.
