I architect and ship production systems across e-commerce, healthcare, IoT, and real-time platforms. 6+ years of PHP/Laravel, Flutter, and distributed systems — from greenfield to scaled production.
I'm a Senior Full Stack Engineer with a deep affection for well-architected systems. I've led engineering teams of up to 10 engineers and owned end-to-end delivery of microservice architectures, cross-platform mobile, IoT control planes, and payments at production scale.
Currently Technical Head at Alltechlabs, where I architected GetDirect — a food-delivery price-comparison engine serving 200+ Indian cities through ONDC.
From a junior Laravel role in Kathmandu to leading a 10-engineer team, then architecting microservices and running engineering for an India-wide marketplace — six roles, one through-line: ship production systems that hold up.
Architected GetDirect as a microservice suite — a live food-delivery price-comparison platform across 200+ Indian cities. Chose Typesense for search, Ably for realtime, Razorpay for payments. Drove ONDC ecosystem integration (Buyer, Seller, Logistics) and built a price-comparison engine scraping Swiggy, Zomato, Magicpin, Uber Eats, and EatSure.
Led a 10-engineer team to deliver a Real Estate Trading platform with AWS Rekognition. Built an HR Management System with ZKTeco biometric integration and Hisaabkeeper accounting; delivered a multilingual Waste Management System with role-based access. Designed SEO-optimized school landing pages on Laravel Nova with Slack-webhook integrations.
Designed microservice Admin / Customer / Seller dashboards for ePeepal, Nepal's multi-vendor marketplace. Drove a 30% performance boost and 40% downtime reduction via PWA, Redis, Laravel Horizon, and Laravel Nova. Stood up CI/CD on Bitbucket with Sentry and Slack integration; built SEO-optimized landing pages with international payment gateways.
Built Digitalpalika, a multilingual eGovernance platform for civil registrations (Birth, Death, Migration, Marriage) deployed across local government bodies. Shipped NepoLive, a BigoLive-style live audio/video streaming app on Ant Media Server with wallet, gifts, credits, and ranking. Delivered the Mailo App backend for multi-restaurant management, farmers' eShop, and bakery delivery.
Shipped Gurudai (formerly Shreevahan), a ride-sharing platform with rider/customer apps, heatmap APIs for geo-sorted dispatch, and a Cargo Air Logistics system. Optimized SQL and indexes for 20× faster retrieval. Contributed to eNewspaper platforms (Aajakokhabar, CapitalNepal) and eShopping Nepal e-commerce.
I take products from a blank schema to production traffic — owning architecture, backend, mobile, and the boring-but-vital parts (CI/CD, observability, payments) that decide whether you ship or stall.
Laravel monoliths, microservice suites, Composer-distributed core packages, event-driven flows, and REST/GraphQL APIs. Built for clarity and rebuild-ability — not for showing off.
Production Flutter apps with bloc and Riverpod state, full Firebase suite, payments, maps, deep links, and crash-free observability. Live on iOS and Android in real markets.
MQTT-based device control, Nayax payment-station integration, Ably/Pusher realtime channels, audiometric tone generation, and Bluetooth medical-device connectivity.
Containerized services, automated deploys, and instrumentation that surfaces problems before users do — so 3am pages become rare instead of routine.
Products and platforms I've architected or shipped — at Alltechlabs, Uptechsys, Peepal International, Zenlab, and Nectar Digit — plus my own side projects and open source.
Microservice suite (admin, seller, mobile API, analytics, comparison) with a Composer-distributed core package. Scrapes Swiggy, Zomato, Magicpin, Uber Eats & EatSure; ONDC integrated; iOS & Android Flutter app with flutter_bloc.
Healthcare technology — hearing-aid web platform and Flutter companion for tinnitus therapy, plus a patient app for audiometry with Bluetooth medical-device connectivity.
Home-services marketplace for Nepal — plumbing, electrical, cleaning, and salon — with Laravel 12 backend, Flutter customer + partner apps, Khalti/Razorpay payments, Sparrow SMS OTP, and Pusher real-time dispatch.
India's sports training marketplace — Laravel + Flutter on iOS & Android. Connects athletes, coaches, and sponsors across 6+ sports: booking, tournaments, verified athlete sponsorship, and equipment commerce.
Broker-free rental marketplace for Kathmandu — owners list rooms and flats free while renters search a map and reveal owner contacts directly. Stacked anti-broker measures (listing caps, 60-day expiry, reports, duplicate detection), map search, and locality SEO pages.
Course & university discovery platform — search and compare programs by fee, location, and degree, or describe what you want in plain English and AI search maps it to the right filters. Role-based access for students, admins, and super-admins with an approval workflow and full technical SEO.
Open-source e-commerce starter on Laravel 13, Inertia & React — full storefront (catalogue, variants, cart, guest/account checkout, order tracking, reviews) plus an admin panel with POS, inventory, CSV import/export, and staff roles. AI natural-language product search parses plain English into category and price filters, with a rule-based fallback. Payments pre-wired for COD, eSewa & Khalti.
Cross-platform Swift tool that turns a Windows ISO into a UEFI-bootable USB installer — with SHA-256 verified writes so a stick that passes actually boots, ESD image support, automatic Intel RST/VMD driver provisioning to fix the "no drives found" bug, and safety rails that refuse the boot disk. Ships a native SwiftUI macOS app and a scriptable CLI from one shared engine.
Nepal's mass-market multi-vendor e-commerce marketplace — microservice Admin / Customer / Seller dashboards. Drove 30% performance boost and 40% downtime reduction via PWA, Redis, Laravel Horizon & Nova.
Ride-sharing platform with rider and customer apps, heatmap APIs for geo-sorted dispatch, and a Cargo Air Logistics Management System. 20× SQL retrieval speedup via index and structure optimization.
Multilingual eGovernance platform for civil registrations (Birth, Death, Migration, Marriage) deployed across local government bodies in Nepal.
BigoLive-style live audio/video streaming app for Nepal — wallet, gifts, credits, and ranking systems on Ant Media Server.

Built an HR Management System with ZKTeco biometric device integration and Hisaabkeeper accounting; multilingual Waste Management System with role-based access.
Two libraries on the public registries — both born from real production needs and still in use in shipped products.
Composer package for programmatic Bing image lookups in Laravel applications. Drop-in service with configurable filters, pagination, and a clean facade — built originally for an internal content tool, then opened up.
composer require vashukarn/bing_image_extractor
Procedural audio generator for Flutter — clean sine, square, triangle, sawtooth waveforms with smooth frequency transitions. I maintain a fork tuned for clinical-grade audiometric tones, used in production at Karn Arogyam for hearing diagnostics.
flutter pub add sound_generator
Also keeping a public Flutter Bluetooth Serial fork around for medical-device prototyping. Source-only, no registry release.

Before you write, here's the short answer to the things people usually ask first.
Yes. I'm based in Kathmandu, Nepal and work fully remote. I keep flexible hours and overlap several hours daily with US Eastern, European, and Indian time zones.
PHP/Laravel (including Livewire 4) on the backend, Flutter for cross-platform mobile, and the surrounding ecosystem — MySQL/PostgreSQL, Redis, Typesense, Docker, AWS, Firebase, Stripe/Razorpay/Khalti, MQTT for IoT, and Sentry/Pulse/Horizon for observability.
I take selective contract engagements alongside my full-time role, typically for architecture reviews, greenfield backend or mobile builds, payments/IoT integrations, or fractional tech-lead work. Email itsvashukarn@gmail.com with the scope.
Yes. I led a 10-engineer team at Uptechsys delivering a real-estate trading platform, and held Technical Head responsibilities at Alltechlabs covering architecture, code review, hiring input, and technology selection across multiple microservices.
Roles where I can own a senior IC track or a small high-leverage team, work on systems that touch real users, and keep the production loop tight. Bonus if there's hardware, payments, or genuine scale involved — e-commerce, healthcare, IoT, and real-time platforms are where my work has landed so far.
