Building Apps That Scale & Impress
I'm Abhishek Tandon — a full-stack mobile & web engineer with 6+ years crafting high-performance Flutter apps, native Android experiences, and enterprise web platforms. From idea to App Store in record time.
6+ Years of Turning Code Into Business Impact
I'm a passionate software engineer based in India, working with global clients to build the digital products they've always envisioned. My expertise spans the full mobile and web stack — from architecting beautiful Flutter & native Android apps to launching polished, high-converting websites and web platforms.
I've built apps used by thousands, integrated with hardware over Bluetooth, architected secure fintech systems, and shipped polished e-commerce platforms. Every project gets my full attention and premium execution.
Premium Engineering Services
From concept to launch — I handle everything, so you don't have to manage multiple vendors.
Flutter Development
Beautiful, natively compiled applications for iOS and Android from a single codebase. Fast delivery, lower cost, maximum reach. I build Flutter apps that feel 100% native — smooth 60fps animations, platform conventions respected.
- check iOS & Android from one codebase
- check Custom animations & micro-interactions
- check App Store & Play Store submission
- check State management: BLoC, Riverpod, Provider
- check REST API & native Android bridge integration
Native Android
High-performance native Android apps built with Kotlin and Jetpack Compose — Google's modern UI toolkit for building beautiful, declarative interfaces. When your app needs deep hardware integration, maximum performance, or full platform control, native is the answer.
- check Kotlin & Jetpack Compose UI
- check MVVM & Clean Architecture patterns
- check Bluetooth Low Energy (BLE) integration
- check Camera2 API & custom sensors
- check Background services & WorkManager
Web Development
Pixel-perfect, lightning-fast websites and web apps that make an impression and drive results. From sleek business landing pages to full-stack e-commerce platforms — built with modern frameworks and tested across every device. See foreverfera.com and titanwayfs.com for real examples.
- check HTML5, CSS3 & vanilla JavaScript apps
- check E-commerce with Razorpay / Stripe
- check Admin dashboards & client portals
- check SEO, Core Web Vitals & accessibility
- check Fully responsive across all devices
WordPress & CMS
Custom WordPress websites, themes, and plugins that go far beyond templates. From blazing-fast business sites to full-blown WooCommerce stores, I deliver CMS-powered platforms that clients can manage with ease and that search engines love.
- check Custom theme & plugin development
- check WooCommerce store setup & optimization
- check Page speed & Core Web Vitals tuning
- check SEO-ready architecture & schema markup
- check REST API integration & headless CMS
Fintech & Security
Financial products demand zero tolerance for errors. I've built compliant payment systems, KYC workflows, and encrypted transaction pipelines. Your users' money and data are protected at every layer.
- check Payment gateway integrations
- check KYC / AML compliance workflows
- check Bank-grade TLS encryption
- check P2P wallet architecture
- check Audit trails & transaction ledgers
UI/UX Design
Design and code under one roof. I deliver Figma-based designs that translate perfectly into pixel-perfect implementations. No designer handoff friction — what you see in the mockup is what you get in the app.
- check Figma prototyping & wireframing
- check Design system creation
- check Pixel-perfect implementation
- check Accessibility (WCAG) compliance
- check Micro-interaction & animation design
Projects That Deliver Results
Real-world applications built for real-world scale. Each project is a story of a problem solved.
Brio Connected Fitness
A health-tech client needed reliable real-time data sync between custom wearable devices and user smartphones — without draining batteries or dropping connections during intense workouts.
Architected a resilient BLE peripheral handling abstraction with strict asynchronous streams ensuring perfect background data alignment regardless of OS interruptions. Built custom GATT characteristic parsers for raw sensor data.
Flawless live-tracking experience, 99.9% crash-free ecosystem, zero reported data loss incidents post-launch. Users loved the seamless feel.
MoConnect Wallet
A fintech startup needed a wallet app capable of instant P2P transfers without UI lag, meeting strict banking security standards.
Built a deterministic application layer with encrypted network handshakes and advanced BLoC state management — UI reflects network responses instantly with zero side-effects causing sluggishness.
Sub-2s full transaction cycles. Balances updated immediately and reliably, dramatically increasing user retention and market trust from day one.
Live Web Platforms
A Process Built for Predictable Success
No surprises. No scope creep. Just clean execution from kickoff to launch.
Discovery Call
We spend 30-60 minutes understanding your vision, constraints, and success metrics. I ask the right questions to uncover what the product truly needs.
Proposal & Architecture
I deliver a detailed proposal: tech stack, architecture diagram, milestone breakdown, timeline, and investment. Full transparency before we sign.
Design & Prototype
Figma screens and interactive prototypes. You see every screen before a single line of production code is written. Changes here cost nothing.
Build & Iterate
Agile sprints with weekly builds you can actually test. Slack communication daily. You're never in the dark about progress — I share TestFlight / Play Console access from day one.
QA & Testing
Comprehensive testing: unit tests, widget tests, integration tests. Real device testing across multiple Android versions and browsers. Firebase Crashlytics & Google Play testing tracks set up before launch.
Launch & Support
App Store and Play Store submission handled. 30-day post-launch support included. Monitoring dashboards configured. Your product is live and healthy.
