Nine years turning expensive, fragile, or manual software into systems people can actually run. Government, healthcare, FinTech, travel, and operations. Right now I work on OpenGov's tax and revenue platform: migrating .NET Framework to .NET 8, replacing Razor and jQuery with React, rebuilding import pipelines to handle 400k-record datasets asynchronously, collapsing Azure sprawl into multi-tenant architecture, and shipping AI skills the team uses for reviews, tests, and daily development. ## Selected work ### 30+ Razor pages moved to React, with no downtime window Led the migration off .NET Framework 4.6.1 and Razor onto .NET 8 and React, on the system public agencies run their budgets on. Every page ships behind a feature flag with a legacy escape hatch. Stack: .NET 8, React, TypeScript ### Imports that stopped falling over at 400k records Rebuilt six synchronous, browser-blocking pipelines as background jobs with live progress. Then traced the recurring out-of-memory crashes to in-memory spreadsheet parsing and made that failure structurally impossible. Stack: Hangfire, SignalR, SQL Server ### 90+ Azure App Services collapsed into one Redesigned the hosting model as a single multi-tenant App Service. Infrastructure cost dropped 70%, and releases became one automated path instead of ninety. Stack: Azure, Multi-tenant, CI/CD ### An agentic reviewer that reads every core change Shipped the PR review skill the team now develops behind—correctness, security, and standards checked before a human looks. Shared infrastructure, not a personal shortcut. Stack: Claude Code, Cursor, AI SDLC ## Approach - Build it once, use it everywhere: When I rebuilt six import pipelines, I wrote the Hangfire + SignalR + staging pattern once and applied it six times. The seventh one takes an hour, not a sprint. - Fix the root cause, not the symptom: Recurring out-of-memory crashes traced back to in-memory Excel parsing. Replaced it with a streaming reader. That entire class of failure is now structurally impossible. - Make the infrastructure do the work: Feature flags, automated reviews, and CI pipelines mean the system enforces standards and the team doesn't burn cycles on process. AI as infrastructure, not as a chat window. - Tests aren't overhead: 398 tests in one sprint. The migration shipped with Playwright coverage because untested pages don't migrate—they get rewritten twice. Most of the leverage in software is not a new framework. It is making the next change cheaper than the last one: clearer boundaries, fewer moving parts, tests that encode the contract, deployments nobody has to shepherd. I use AI the same way. Not as a chat window beside the work, but as infrastructure inside it—skills for review, tests, and scaffolding, constrained by the team's architecture and taste. Spec-Kit and OpenSpec-style specs, an explicit review bar, and an AI-aware SDLC are how generation stays useful instead of noisy. That is also how I lead: I still write the important code. I make the system around it something a team can run without me in every loop. ## Full history ### Software Engineer III, OpenGov India Private Limited (Jan 2025 – Present) - Led the migration from .NET Framework 4.6.1 to .NET 8, and from Razor and jQuery to a React 18 and TypeScript SPA—30+ pages so far, each behind a feature flag with a legacy fallback and Playwright coverage. - Consolidated 90+ Azure App Services into a single multi-tenant App Service, cutting infrastructure cost by 70%. - Rebuilt six synchronous import pipelines as asynchronous Hangfire jobs with SignalR progress, so 400k-record datasets process in the background instead of timing out in the browser. - Root-caused recurring OutOfMemoryException failures to in-memory Excel parsing, replaced it with a streaming reader, and shipped a same-day production hotfix. - Built the LaunchDarkly feature-flag service the platform now uses for gating, targeting, and percentage rollouts. - Shipped an agentic PR review skill as shared team infrastructure, checking correctness, security, and standards on every core-module change. - Delivered customer-specific systems end to end, including Hawaii County's property tax loan platform and installment-aware charge grouping for Amsterdam, NY. - Automated deployments with CI/CD pipelines and scripts, and contribute to architecture decisions and CRD resolution. ### Tech Lead, Coditas Solutions LLP (Oct 2023 – Jan 2025) - Shipped work across Healthcare, FinTech, and Sales as both a lead and an individual contributor. - Refactored production applications to run about 80% faster than the systems they replaced. - Modernized legacy WebForms applications onto React and .NET 8 without pausing delivery. ### Senior Software Developer, Coditas Solutions LLP (Jan 2023 – Sep 2023) - Built microservice-oriented work in Sales and Travel. - Designed integrations that reduced multi-step human processes to a single click, including a custom SSO authentication library. - Led a team of five while remaining hands-on, picking up unfamiliar technologies when the project required it. ### Software Developer, Coditas Solutions LLP (Dec 2020 – Dec 2022) - Delivered scheduling and label-printing systems that cut user time by about 75% and removed configuration toil. - Set up ETL from on-premises databases to the cloud, bringing sync latency close to zero. ### Senior Software Developer, Sciffer Analytics Private Limited (Apr 2019 – Dec 2020) - Owned a Fleet Management FinTech product from architecture through delivery. - Compressed a 3–5 week feature cycle into immediate user execution, removing the developer from the loop. - Managed a team of five, coordinated with Android engineers, and ran the project's DevOps. ### Software Developer, Sciffer Analytics Private Limited (Apr 2018 – Mar 2019) - Built studio management and allocation for an entertainment product, moving a fully manual process to semi-automation. - Led the project from architecture through delivery with a team of three. ### Intern, Sciffer Analytics Private Limited (Aug 2017 – Mar 2018) - Maintained a Node.js and Meteor codebase while also shipping PHP and .NET. - Contributed to requirement gathering and documentation. ## Skills - Systems: C#, .NET / .NET Core, MVC, Hangfire, SignalR, Python, REST, SOAP, Entity Framework Core - Interface: React, TypeScript, TanStack Query, JavaScript, HTML / CSS, Blazor, React Native - Data: PostgreSQL, MSSQL, MySQL, MariaDB, MongoDB, Redis - Cloud & delivery: Azure (Cloud + DevOps), Azure Blob Storage, AWS, GCP, Docker, CI/CD, LaunchDarkly, Jenkins, Apache Airflow, ELK - Identity: Auth0, SSO, SAML 2.0, OAuth 2.0, OIDC, JWT, Active Directory, SP- and IdP-initiated auth - AI: OpenAI, Claude, Copilot, Llama, Perplexity, Cursor, AI SDLC, Spec-Kit, OpenSpec - Quality: TDD, xUnit, NUnit, Moq, Jest, Vitest, Playwright, Design patterns ## Education - Master of Computer Applications, Savitribai Phule Pune University (Apr 2018), 71.18% - Bachelor of Computer Applications, Savitribai Phule Pune University (Apr 2015), 70.88% ## Certifications - Mobile Rapid Prototyping - Scaling Web Apps with Cosmos DB - .NET Core Microservices - Entity Framework in Depth ## Optional - [HTML profile](https://allanmascarenhas.com): Human-readable site - [JSON profile](https://allanmascarenhas.com/profile.json): Structured profile data - Resume: Available on request
