Strong software is not defined by features alone. It is defined by clarity of architecture, quality of experience, and the ability to scale without constant rewrites. I bring over 10 years of software engineering experience, including 7+ years in financial technology environments supporting Fortune 50 organizations. That experience shaped how I approach systems today: disciplined architecture, secure foundations, thoughtful engineering decisions, and long-term maintainability. I carry those same standards and work ethic into every engagement executed by my team. At ISAI Tech Solutions, I lead the development of modern SaaS platforms and intelligent AI-driven systems with structured execution and senior oversight. Every project is approached with both engineering depth and product perspective. Technical decisions are evaluated not only for correctness, but for how they impact scalability, performance, security, and future roadmap flexibility. My experience includes building and supporting: • Subscription-based SaaS platforms with role-based access and scalable backend architecture • High-volume data processing and reporting systems • Secure API ecosystems integrating third-party services and automation workflows • Cloud-native deployments with CI/CD pipelines and production monitoring • AI-enhanced features embedded directly into operational workflows Each engagement is led with senior architectural oversight. When scale is required, I assemble carefully selected engineering contributors who operate within defined scope, structured delivery, and clear accountability. If you are evaluating a technical partner for your SaaS platform or AI-enabled product, feel free to reach out with project details. I am happy to review scope and provide structured next steps.

**Need to connect an LLM to your real tools - email, databases, APIs, internal systems - and have it work reliably in production? That's what I build.** I've shipped my own MCP (Model Context Protocol) server that gives Claude live access to 9 functional domains - email, git, filesystem, calendars, contacts, scheduling - and I run it in production every day. I've also built a full AI content pipeline of Claude Code agents that publish directly to a live CMS. Behind that is nearly 30 years as a software architect and full-stack engineer - and I still write code every day. So your AI integration sits on a backend that won't fall over. My professional background: 18 years as Technology Architect at Old Republic Home Protection, where I designed and built two enterprise platforms from greenfield. One was a microservices SOA system (Java/Spring Boot, Angular, RabbitMQ, SQL Server). The other was a cloud-first Azure platform (Docker, Azure Service Bus, Cosmos DB). I led a development team, ran CI/CD, introduced Security-by-Design and TDD, and was the person they called when projects went sideways. Before that: Senior Application Architect at MultiPlan in New York, building healthcare claims systems at scale (700+ users, 1.2M+ provider records). Since 2024, I've been building and running my own software products - several are live and in production: - Itty - A branded link-shortening SaaS with custom domains, click analytics, multi-user management, and Stripe billing. Built on Java 21 / Spring Boot 4 / Angular 21. - Klass Paperless - A digital template store for reMarkable tablets. Includes a headless-browser PDF generation pipeline, Stripe checkout, AWS S3 storage, and an Angular storefront. - Klass Video - A 4K AI video restoration and upscaling service. - Klass Wiki - A technical reference and blog I publish covering Spring Boot, SQL Server, Angular, Linux, and AI development. - Klass CMS - A multi-tenant CMS platform serving 8+ distinct websites from a single Spring Boot deployment. Configuration-driven interceptor pipeline chains honeypots, AI spam-detection, landing-page tracking, S3 presigned redirects, Stripe checkout, and mailing-list signups. Built on Java 21 / Spring Boot 3.5 / Spring AI / Angular 21. - Klass CRM - A native CRM and personal productivity app built with SwiftUI and SwiftData for macOS 15+ and iOS 18+. Full end-to-end encryption (Argon2id + AES-256-GCM), CloudKit sync, Markdown I/O, and a modular architecture across CRM, Finance, Planner, Notes, and Templates modules. I also built my own AI agent infrastructure: a Spring AI MCP server that integrates email (IMAP/SMTP), git, CardDAV contacts, CalDAV scheduling, and filesystem operations for Claude-based automation. On top of that I built an AI content marketing pipeline - custom Claude Code agents that generate weekly LinkedIn posts, blog articles, and social content from a single subject prompt, enforcing brand voice and publishing directly to the CMS. **What I work in:** - Backend: Java, Spring Boot (through v4), Grails/Groovy, REST APIs, microservices, Spring Security, JWT, OAuth 2.0 - Frontend: Angular (v17-21), TypeScript, React, Next.js - Native desktop/mobile: Swift, SwiftUI, SwiftData (macOS/iOS); JavaFX; Tauri 2 (Angular + Rust cross-platform desktop) - Databases: SQL Server, SQLite, MySQL, Oracle (PL/SQL), Azure Cosmos DB, MongoDB - Cloud: Azure (VMs, Spring Cloud, Service Bus, Containers, Cosmos DB, Blob Storage), AWS S3, CloudKit, Backblaze B2, Cloudflare R2 - AI/LLM: Spring AI, Anthropic Claude API, Azure OpenAI (including Assistants API), MCP server implementation, Claude Code agent pipelines - Integrations: Stripe, SendGrid, Okta/SAML, Telegram Bot API, Etsy, IVR/phone APIs, EDI - Tools: Docker, Azure Pipelines, Gradle, Quartz Scheduler, Selenium/WebDriverManager, JUnit 5, XCTest I work across the full stack and adapt to what the project needs. I work independently without hand-holding, communicate clearly with non-technical stakeholders, and deliver. If you need an MCP server built, an LLM wired into your existing systems, or a senior engineer to take a stalled project and just ship it, I'd be glad to talk.

Hi I'm Mylene. I build automations, full systems, and custom solutions that solve my clients’ problems. For the past 8 years, I’ve worked directly with decision-makers, developers, and end users. I handle systems from design through implementation. I do full code, low code, and no code. I build AI agents and systems from scratch. I know what I build inside and out. If you have a clear problem, my job is to design and build the solution that solves it. ⸻ Business problems I've helped solve: 🔶 Unsustainable business operation costs 🔶 Time consuming, manual, repetitive processes 🔶 Error prone workflows creating bottlenecks and delays 🔶 Processes split across tools that do not work together 🔶 Outdated systems that can no longer keep up with the business If you recognize your problem here or something similar, reach out with a short description of what you’re trying to fix. ⸻ Systems I have built 🔷 Core business operations automation Automate end to end workflows and systems with minimal or no human handling. 🔷 AI managed inbox and message handling systems Automatically triage incoming messages, draft responses, escalate edge cases with context, and log outcomes into internal systems. 🔷 AI chatbots for customer handling and lead intake Handle website inquiries, collect lead information, qualify inputs, and schedule next steps without manual follow up. 🔷 Document and report generation systems Generate standardized documents and reports from raw inputs. ⸻ Outcomes my clients typically see: • Significant reduction in operational costs • Faster execution across core workflows • Fewer manual handoffs and errors • Reduced dependency on unnecessary roles • Weeks or months of reclaimed time across teams ⸻ I work across modern automation, the latest AI tooling, and of course have mastered n8n, Make, Zapier, and Google Vertex among others, But I think Tool choice follows the system design, not the other way around. But I am up to date with what is cutting edge and have mastered most core tools. ⸻ If this aligns with what you’re working on, feel free to reach out with the problem you’re trying to solve right now.
