Hi, I'm Owais. I've spent 7+ years building data systems across enterprise and startup environments. I've set up entire data platforms from end-to-end on AWS, Azure, and GCP, including in SOC 2 and HIPAA environments. I've built ETL pipelines that don't break at 3 AM, modeled warehouses that survive contact with real business logic, and shipped dashboards people actually open. These days I help growth-stage startups build analytics platforms around AI without bleeding money on it. Natural language to SQL, agents that surface insights instead of waiting to be asked, automated anomaly detection, the kind of features your customers are starting to expect. Most AI-in-analytics projects don't fail because the model isn't good enough. They fail because the foundation underneath it is a mess. A well-documented dbt project does more for AI accuracy than a bigger LLM, and if your dashboards aren't getting opened, adding AI on top doesn't change anything. If you're trying to build AI-powered analytics and want someone who's done the unglamorous work that makes it actually useful, let's talk.

Backend Engineer specializing in Go (Golang) and Java/Spring Boot, with hands-on experience designing and shipping production-grade VoIP, predictive dialer, ringless-voicemail (RVM), and AI voice-bot platforms. What I build for clients: - Telephony platforms: 20+ Go microservices powering Predictive Dialer and Ringless Voicemail (RVM) suites including admin, provisioning, billing, CDR, event, and VoIP APIs. - AI voice bots: real-time conversational agents that stream call audio between Asterisk (AudioSocket) and cloud LLMs, using AWS Bedrock and Google GenAI for reasoning, Deepgram for speech-to-text, and ElevenLabs for text-to-speech, delivering sub-second response latency over WebSocket. - Mobile app backends: Spring Boot 3 / Java 21 services powering an eSIM/virtual-SIM app (2Sim) with authentication, SIP calling, SMS, voicemail, push notifications (FCM + APNs), in-app purchases (RevenueCat), and email (Brevo). - Asterisk at protocol level: integrations via AGI, AMI, and AudioSocket, with DTMF detection, voice-activity detection (ONNX), and full call recording in pure Go. - Payment integrations: Stripe (one-time payments, subscriptions, webhooks) and RevenueCat with secure server-side validation and reconciliation. - Data pipelines: Call Detail Records on ClickHouse, MongoDB, and Redis, with S3-backed call recordings, scheduled aggregations, structured logging, and graceful shutdown. Tech I use most: Go, Java 21, Spring Boot 3, Echo, Gorilla, REST, WebSocket, gRPC, OAuth2, JWT, Microservices, PostgreSQL, ClickHouse, MongoDB, Redis, MinIO, AWS (S3, Bedrock), Docker, Liquibase, Asterisk. I focus on clean architecture, observability, and shipping features that scale reliably under production traffic. Let's connect if you need a backend engineer for Go services, real-time/telephony systems, or AI voice products.

Your app slows down under real traffic, the queue backs up, or a realtime feature falls apart at scale - that's the work I take. Backend engineer in PHP/Go for high-load SaaS, fintech and data-heavy platforms. What I've shipped: - Realtime engine in Go - Crypto trading platform - SEO analytics platform - Subscription streaming product - Service marketplace - Offline-first PWA - Admin panels and internal tools I genuinely enjoy what I do. The most valuable motivation for me is feedback from clients and end users. When I see that the product I’ve worked on actually helps people or makes them happy, it inspires me to keep improving and do even better.
