Problem: Sellers on Pakistan Post typed the same booking forms and money orders for every parcel. At hundreds of COD orders a week that is hours of copy-paste and typos, with no tracking after handoff. Role: Sole engineer: architecture, web app, mobile app, Shopify app, infra, and day-to-day ops. Challenge: Pakistan Post has no public API docs. Booking, money orders, and labels hit internal endpoints, so I reverse-engineered the request flow and wrapped it in something that survives upstream outages. Bulk loadsheets across hundreds of orders still had to finish fast and atomically. Outcome: Live at postbookingagent.com with free and paid plans, a Shopify app, and a React Native Android app. The product site lists 10,000+ customers served. Stack: React, Node.js, React Native, MySQL, Shopify API, Docker, Nginx, VPS. ### Tallify Bookkeeping and carrier commissions for insurance agencies · saas · 2024 – 2026 · [Case study](https://zahidlatif.dev/projects/tallify) · [Live](https://tallify.ai) AI-assisted bookkeeping for independent US insurance agencies: Plaid bank feeds in, reconciled commission statements and GAAP-ready books out. Problem: Agencies reconcile statements from a dozen carriers against their books by hand. Money slips through, nights disappear, and tax season hurts. Role: Core engineer at X Assure by eDesk: Plaid integration, AI categorization, OCR intake, reporting UI. Challenge: Money has to balance. The pipeline pulls banks through Plaid, OCRs receipts and invoices, and uses AI to suggest categories, but every suggestion is logged and reversible. Nothing posts silently. Volume is 50K+ transactions a month. Outcome: Live at tallify.ai for independent agencies. Plans from $349/mo. Integrations with QuickBooks, Xero, and agency management systems, plus a chat UI for questions over the books. Stack: Next.js, Node.js, Python, PostgreSQL, Plaid, Azure OCR, OpenAI API, Redis. ### Receptionist AI No-code voice agents that call and book · saas · 2024 – 2026 · [Case study](https://zahidlatif.dev/projects/receptionist-ai) · [Live](https://tryreceptionist.ai) No-code voice agents for outbound and inbound calls: qualify leads, book meetings, and fire SMS, email, WhatsApp, or calendar actions while the call is still live. Problem: Missed calls cost sales. Hiring callers around the clock is expensive. Most bots cannot finish a booking or hand off cleanly. Role: Core engineer: telephony integration, lead automation, SaaS dashboard. Challenge: Latency comes before model quality. STT, reasoning, and TTS must stay under ~500ms round-trip or the call feels dead. Call state, CRM rows, and calendar writes have to stay in sync when someone interrupts, switches language, or drops mid-booking. On top: flow builder, RAG knowledge bases, Zapier and webhooks. Outcome: Live at tryreceptionist.ai. Inbound and outbound in 100+ countries, 11+ languages with auto-detect, sentiment scoring, drag-and-drop flows, and integrations from Salesforce to Cal.com. Free and Pro plans with a 14-day trial. Stack: Node.js, Python, WebSockets, Telephony APIs, OpenAI API, ElevenLabs, PostgreSQL, Redis. ### Ayei.ai Custom AI assistants, shipped in days · saas · 2025 – 2026 · [Case study](https://zahidlatif.dev/projects/ayei) · [Live](https://ayei.ai) Custom AI assistants for sales, marketing, bookkeeping, research, reception, and similar roles. Each one is wired to the client's workflow and runs 24/7. Problem: Small teams lose hours on repetitive work but cannot hire for every function. Off-the-shelf AI tools rarely match how they operate; bespoke automation usually means a long consulting engagement. Role: Core engineer: assistant runtime, per-client workflow setup, intake-to-production pipeline. Challenge: Every client wants different steps. The platform mixes reusable blocks (monitoring, outreach, reporting, bookkeeping) into isolated deployments that stay auditable and cheap enough to leave running. Outcome: Live at ayei.ai with eleven assistant types, from lead qualification to executive support. Each build is custom and typically live within days of intake. Stack: Next.js, Node.js, Python, OpenAI API, PostgreSQL, Automation APIs. ### X Assure Ops platform for a 250-person VA team · platform · 2023 – 2026 · [Case study](https://zahidlatif.dev/projects/xassure) · [Live](https://xassure.ai) Internal ops and project management for X Assure, eDesk's VA service for insurance agencies: projects, tasks, and time tracking across a distributed team. Problem: A VA shop with hundreds of assistants across time zones needs more than spreadsheets for client accounts, tasks, and billable hours. Role: Core engineer: data model, realtime sync, time tracking, collaboration features. Challenge: Check-in/check-out hours feed payroll and client billing, so the numbers have to be trustworthy. Supabase (Postgres, auth, edge functions, realtime) keeps presence, tasks, and hours live without a separate socket layer. Outcome: Powers operations at xassure.ai ('X Assure by eDesk'). Public site cites 150+ agencies and a 250+ person team with a 4.7 Trustpilot score. Stack: React, Next.js, Supabase, PostgreSQL, Edge Functions, Realtime. ### ShopCourier Multiple Pakistani couriers, one dashboard · saas · 2025 – 2026 · [Case study](https://zahidlatif.dev/projects/shopcourier) Multi-tenant SaaS for Pakistani COD sellers: one API and dashboard across courier services. Also my final-year university project. Problem: Sellers bounce between TCS, Leopards, Pakistan Post, and other portals with different booking flows, tracking, and COD reconciliation. Changing couriers per parcel means re-entering everything. Role: Solo build: multi-tenant architecture, courier integrations, checkout tooling, webhooks. Challenge: Checkout does geocoding-based city and postcode autofill. Pakistani addresses are messy; mapping free text to courier service zones is the hard part. Shopify and WooCommerce webhooks must be idempotent per tenant. Outcome: Final-year project, built on what Post Booking Agent taught me about courier logistics. Stack: Next.js, Node.js, PostgreSQL, Shopify Webhooks, WooCommerce, Geocoding APIs. ## Published apps 8 apps; 7 Play listings; 6 App Store listings.
