We turn your app idea into a live product on the app stores.

Flutter apps. PHP backends. AI integrations. One team handles the full stack, managing the entire lifecycle from first wireframe to store submission. No outsourcing, no handoffs, no surprises.

Ecosystem Architecture

How we build your product.

We engineer your application as a unified full-stack ecosystem. From the user interface to the server database, our team manages the entire pipeline—though we are modular enough to plug directly into your existing codebase.

Layer 01 | Frontend Interface

Cross-Platform Flutter Development

One codebase. Universal deployment. We build responsive, production-ready applications compiled to run natively on iOS, Android, Web, and Desktop (macOS & Windows). Expect pixel-perfect responsive layouts, fluid 60fps animations, and a unified architecture that cuts development and maintenance costs in half.

Layer 02 | Infrastructure

Backend Systems & Database Architectures

High-performance RESTful APIs and server-side workflows. We build robust systems using PHP/Laravel and Node.js, combined with modern real-time backends and databases like Firebase, Supabase, PostgreSQL, and Redis to ensure transactional integrity and live database sync.

Layer 03 | Intelligence

Practical AI & LLM Integrations

Supercharge your applications by integrating cutting-edge LLMs (Gemini, Claude, GPT), semantic search indexes, and vector database embeddings to solve concrete business workflows. (Note: We focus on prompt engineering and API-level integrations; we do not train custom LLMs or build custom ML models from scratch.)

MVP Sprints & Store Launch

Accelerate your time-to-market. We manage the entire lifecycle from early-stage scoping to compilation, App Store & Google Play Store compliance auditing, metadata setup, and successful store listings.

Key Differences

Why teams choose us over larger agencies.

You collaborate directly with the engineers building your product ecosystem. No project managers translating requirements, no artificial handoffs. We align your frontend, backend infrastructure, and intelligence layers in a single, fluid development cycle.

From the Founder

A high-performance product is a unified ecosystem. By aligning the cross-platform frontend, database infrastructure, and intelligence layers under a single, direct engineering roadmap, we deliver secure software that scales naturally from initial scoping to app store release.

— Samiullah, Founder of NEXLSOFT

You Talk to the Engineers

No sales reps or account managers. You collaborate directly with Samiullah and the engineers writing your code. Questions get answered in real time, and technical decisions translate to working code within the same sprint.

One Codebase, Universal Reach

Using Flutter, we compile natively to iOS, Android, Web, and Desktop from a single codebase. This ensures total feature parity across all platforms, dramatically cuts down bugs, and reduces development and maintenance timelines by 40%.

We Run Production Software

Our own product, Earniva, is live on the Google Play Store with real users, live databases, and transactions. We don't just build apps for clients—we deal with backend database scaling (Firebase/Supabase), payments, and console compliance policies weekly.

Development Lifecycle

How we build.

Four phases. Complete transparency. From technical blueprint to active App Store listing.

01
feat(scoping)

App Scoping & UX Blueprint

We map out your app's screens, database schema, and cross-platform architecture (iOS & Android). You get a complete interactive wireframe and technical spec blueprint before we write the first line of code.

STAGE_01ARCH_BLUEPRINT: READY
02
feat(flutter-dev)

Flutter Dev & API Integration

We write clean, high-performance Flutter code, set up secure cloud databases (Firebase/Supabase), implement state management, and integrate APIs. You receive weekly live TestFlight and Play Console builds.

STAGE_02TESTFLIGHT: VERIFIED
03
feat(deployment)

Device Testing & Submission

We run automated tests on multiple physical screen sizes, verify offline caching, and optimize app sizes. Then, we coordinate the entire App Store and Google Play submission, handling compliance and ASO metadata.

STAGE_03STORE_COMPLIANT: PASS
04
feat(maintenance)

OS Compliance & Security

Post-launch, we monitor crashlytics logs, optimize database index costs, and push required iOS/Android updates. We help you scale, audit location fraud, and continuously optimize the user experience.

Common Questions

Straight answers about how we build cross-platform mobile apps, manage databases, and handle store submissions.

Flutter compiles directly to native machine code for both iOS and Android. This guarantees a smooth 60fps/120fps UI performance while writing the code once. It cuts launch timelines by 30-40%, saves backend API duplication, and ensures updates deploy to both Apple and Google stores simultaneously.
App Store guidelines are strict, especially regarding user data, safety rules (Apple's App Tracking Transparency), and monetization. We manage the entire submission process, including metadata writing, ASO keyword research, screenshot creation, and resolving any compliance requests from Apple and Google review panels directly.
Both. If you have an existing system, we build secure API integrations. If you are starting fresh, we engineer robust backend architectures using Laravel or serverless cloud ledgers (Firebase/Supabase). All structures are built to scale automatically as your app's user base grows.
You do. 100%. We sign a formal Intellectual Property (IP) transfer agreement and NDA before kickoff. Your code repository, Figma visual systems, and launch configurations belong to your company from day one.
Apps are live systems. We set up automated crashlytics reports and performance alerts. We offer structured monthly retainers to handle OS compliance updates (e.g., new iOS/Android version releases), feature scaling, and backend API monitoring.
Yes, we recommend it. We specialize in launching high-quality MVPs within 4 to 8 weeks. This allows you to collect real user data and test market hypotheses without over-engineering features before validation.
