B2B SaaS platform (project management + marketing suite), 50K+ monthly active users. Joined as one of the first few engineers on a 24 person team and built many of the product's core features from the ground up. Cross-Platform Mobile App (Ionic): Built the iOS and Android app on Ionic + Angular with Capacitor. Set up the app shell, reused much of the web product's Angular services, and built the mobile flows for task management and push notifications. Live on the App Store and Play Store; 15K+ installs so far. Multi-View Rendering Engine: The same task data renders as 5 different views (List, Board, Calendar, Timeline, Gallery). I built a shared Angular data layer (v15+, standalone components) with a view-adapter pattern so adding a new view doesn't mean rewriting data fetching. Formula & Custom Fields Engine: Notion-style formula fields, built end to end. The parser is a Chevrotain lexer plus a recursive-descent grammar and a BaseCstVisitor evaluator, handling 15+ functions and operator precedence. On the Angular side I built the formula input with autocomplete, a live result preview, and error states for bad expressions. Lets non-technical users define their own computed fields. Real-Time Collaborative Editor & Chat: Tiptap/ProseMirror editor with live multi-user editing, comment threads, and @mentions. Tiptap was still thin on extensions back then, so I went into the ProseMirror source and implemented the missing pieces myself (custom mentions, drag handle, slash menu, emoji picker, etc.). White-Label Customer Support Portal: A separate client-facing app where a client's own customers log in to raise and track requests, while the client's team handles them inside SmartTask. Two-sided design with strict permission isolation between the two, plus per-client branding from one codebase. Runs for 20+ branded clients. Performance & Mentorship: Tracked down Angular change-detection bottlenecks with memoization and virtualization, cutting interaction latency ~20% (Azure monitoring). Mentored 2 junior engineers. File Proofing & Annotation: Built proofing/annotation feature for images, PDFs, and video. Reviewers can mark up a file directly and leave comments pinned to a spot or a video timestamp. I used pdf.js and video.js for rendering and wrote the annotation layer on top, plus the APIs to store it all. Karma Points & Rewards: A points system that scores activity (tasks, projects, comments) and lets each client set their own point values and rewards. Built the whole thing: the scoring rules on the backend, the admin screen for configuring it, and the leaderboard UI. Also built: S3 presigned-URL uploads, an in-app email client, and a dashboard/reporting layer shared across several features.

Taught and mentored international students, simplifying complex, analytical topics into clear step-by-step explanations and adapting my approach to each student's level early proof of the problem-solving and communication I now apply to engineering.
