Waseeq has spent the last 5 years building apps from the ground up, usually owning everything from the mobile client to the back end and, more recently, the AI features too. Recent work includes an offline sync engine that keeps a law firm's billing records safe without internet, and an on-premises LLM platform he reworked to cut setup time by 30%. He also co-founded Fanoon, a Top 100 startup, and enjoys working closely with teams to turn rough ideas into finished products.

Work Experience
Lead Product Engineer
The Rider Network
- Served as solo founding engineer for a non-technical founder, turning a riding community idea into live iOS and Android apps with a Supabase back end, launched on both stores in about 4 months.
- Acted as the founder's technical partner, translating goals into a phased roadmap and picking a managed stack so one engineer could build and run it, keeping hosting almost FREE per month.
- Led the founder through developer accounts, store listings, privacy and data-safety forms, and App Store and Google Play review, so a first-time founder shipped 24 builds without hiring a team.
- Built a group ride safety system alone that spots riders who fall behind or lose signal and alerts them and the organizer by push within about 1 minute, the app's core promise to riders.
- Shipped paid plans with RevenueCat and enforced them in the database, giving the founder a working revenue model from launch and closing a gap that let free users create paid rides.
- Delivered the full product solo, from a map of rider-added places and live group rides to events and memorial pages, reaching about 300 riders in the first months.
- Gave the founder tools to run the app without engineers: an admin moderation queue, crash reporting, analytics, a forced-update switch, and an hourly health check on the safety system.
AI Product Engineer
Doodle
- Owned an AI-powered event networking app end to end, from Flutter and BLE to back end and RAG, letting attendees at large venues connect and book meetings instantly, growing from a 4-month MVP to 25,000+ users.
- Solved networking failures caused by overloaded venue Wi-Fi by building offline-first BLE discovery and contact exchange, with around 95% of connections completing without internet.
- Designed an offline booking sync that queued meetings on-device and reconciled them once connectivity returned, keeping sync conflicts under 1% during peak event traffic.
- Built a RAG-powered event assistant over schedules, speakers, and venue information, answering attendee questions instantly and resolving around 40% of queries without the organizer's staff.
- Replaced business cards and email back-and-forth with one-tap BLE meeting booking, cutting time to book from minutes to under 10 seconds and enabling around 8,000 meetings booked per month.
AI Product Engineer
Sixmin
- Shipped a legal practice-management platform end to end in 2 months, with a Next.js web app and Flutter iOS and Android apps on a shared Supabase back end, serving 40+ law firms in its first quarter.
- Built an AI agent that combines RAG over firm documents, receipts, and expense policies in Supabase with tool calls into billing data, answering attorney questions in seconds instead of around 10 minutes.
- Secured the agent for legal use with firm-scoped retrieval, read-only tools, audit logs, and refusal of legal advice, reaching around 92% accuracy on a 150-query test set with zero cross-firm data exposure.
- Replaced unreliable iCloud sync with an offline-first architecture across web and mobile, queuing changes locally and syncing to Supabase with conflict resolution, with zero billing-record loss offline or across updates.
- Isolated each firm's client and billing data at the database layer with Supabase row-level security and Sign in with Apple, meeting the confidentiality bar that law firms require.
- Built court e-filing workflows that let attorneys prepare and submit filings inside the platform instead of separate portals, cutting filing prep time by around 50%.
- Built 6-minute-increment billing at the data layer with automated invoice PDFs and RevenueCat subscriptions, eliminating manual billing reconciliation and launching paid plans at release.
Senior Software Engineer
CodingCops
- Collaborated within a cross-functional Agile team of 50+ engineers, participating in sprint planning, retrospectives, and code reviews while resolving Git merge conflicts and maintaining clean branching workflows across 3+ parallel workstreams.
- Revamped the architecture of an on-premises LLM infrastructure platform, redesigning 5+ core system components to improve scalability and deployment flexibility, cutting infrastructure setup time by 30% for enterprise users on private infrastructure.
- Architected and delivered 5+ full-stack applications from zero to production, owning end-to-end technical decisions across the front end, back end, and infrastructure while consistently meeting deadlines across teams of 10+ stakeholders.
Full-stack Mobile Engineer
Genuity
- Shipped a Flutter mobile app (iOS, Android) giving technicians ticket triage, updates, and push notifications on the go, with offline-first caching so queues stayed usable in low-connectivity sites.
- Built back-end services across Ruby on Rails and Python/FastAPI, plus event-driven background processing (Sidekiq) and Cron workflows for SLA reminders, digests, and cleanup.
- Cut API response times 40% by profiling with New Relic APM, eliminating N+1 queries, and refactoring PostgreSQL access paths.
- Built the mobile to back-end API layer and real-time notification flow end-to-end, from Figma designs to App Store release.
- Designed a gamified engagement layer on the core ticketing workflow, lifting user engagement 25%.
- Integrated Slack and Microsoft Teams APIs for real-time ticket delivery; maintained RSpec unit and integration suites for regression-free releases.
Full-stack Mobile Engineer
Petersen Automotive Museum
- Wrote a custom Flutter plugin in Kotlin and Swift over platform method channels and platform views to wrap the Mapbox Navigation SDKs, since no existing package supported the use case.
- Owned the product end-to-end: Flutter iOS/Android client, Python/FastAPI services, and a Next.js web companion sharing one REST contract and one back end.
- Built the real-time social feed on FastAPI with async WebSockets and Celery workers, pushing likes, comments, and notifications to 5,000+ active users in under a second.
- Ran NSFW moderation on-device with TFLite models on iOS and Android, so user photos never left the phone, and filtering added no server latency.
- Built an offline-first layer with local persistence and background sync, keeping wayfinding and feed content usable in gallery dead zones.
- Tuned the FastAPI and PostgreSQL layer with async endpoints, indexing, and Redis caching to hold p95 latency steady as feed traffic grew.
Mobile Engineer
Freelance Clients
- Built a cross-platform fitness app in Flutter and Firebase, integrating Google ML Kit for real-time exercise pose estimation at a smooth 60fps using the device camera.
- Engineered heuristic algorithms with complex mathematical models to accurately calculate BMI and body metrics from facial image analysis, eliminating manual user input.
- Implemented an offline-first BMI calculation pipeline using a locally bundled XGBoost model converted to TFLite, delivering accurate results in under 5 seconds with zero network dependency.
- Architected a scalable Firebase back end supporting real-time data sync, user authentication, and persistent fitness tracking across sessions.
