Product Engineering • Cross‑Platform SaaS • Scalable Backend Architecture
I lead Deventee, an engineering studio focused on scalable, maintainable, production‑grade software — from MVPs to complex SaaS platforms and cross‑platform applications. We solve real business problems with robust execution, not prototype code.
- Design multi‑tenant SaaS architectures with secure authentication, modular APIs, service isolation, and feature toggles.
- CI/CD builds with automated testing, quality gates, deployment pipelines (e.g., GitHub Actions, Codemagic).
- Apply Clean Architecture (SOLID, Modularity, Hexagonal) to enforce testability and long‑term code health.
- Single‑codebase delivery to iOS, Android, Web, Desktop with high‑performance UI and adaptive layouts.
- Scalable state management with Riverpod / Bloc, avoiding anti‑patterns like large inherited widget trees or unbounded rebuilds.
- Custom widget systems and animation pipelines (no UI lift‑and‑shift boilerplate).
- API‑first backends (REST/GraphQL), secure OAuth2/JWT token flows, rate limits, RBAC.
- Firebase for rapid backend delivery: Auth, Firestore, Cloud Functions — with structured data and security rules.
- AWS / serverless alternatives where cost, scale, and reliability demands exceed BaaS.
- OWASP‑aligned threat mitigations, encrypted storage, secure key usage.
- Observability setup (Crashlytics, Sentry, performance logging).
- Automated test suites: unit, widget, integration with coverage targets.
We deliver engineering outcomes with measurable impact — not slides or static mocks.
Standard Deliverables Include:
- SaaS Platforms: granular roles, analytics dashboards, subscription workflows.
- Mobile & Web Apps: real‑time features, offline sync, push notifications.
- Admin Panels & Dashboards: data insights, reporting, permission models.
- DevOps Pipelines: automated testing, staging, production deployment.
| Project | Scope & Impact | Tech |
|---|---|---|
| Social Network MVP | Full feed, follow system, stories, real‑time notifications; Riverpod for state isolation and efficient updates. | Flutter, Firebase |
| Real‑Time Messenger App | Low‑latency messaging, delivery receipts, offline queueing. | Flutter, Firestore |
| Enterprise SaaS Features | Subscription management, usage analytics, secure APIs. | Firebase + AWS |
| Utility & Productivity Tools | QR code systems, secure auth engines, reusable UI systems. | Flutter |
These are engineering outcomes — not templates. Each supports growth and production use.
- Flutter, Riverpod/Bloc, platform channels where native is required.
- Firebase: Auth, Firestore, Functions (with structured rules & indexes).
- REST/GraphQL APIs with secure token systems (OAuth2 / JWT).
- AWS serverless or containers for high‑traffic services.
- CI/CD (GitHub Actions, Codemagic, automated test runners).
- Crash analytics (Crashlytics, Sentry).
- Performance profiling and metrics dashboards.
Bad option: shipping untested, unmonitored apps with brittle logic. Better option: structured codebases with:
- ≥80% core logic test coverage.
- Clear modular boundaries.
- Automated quality gates in build pipelines.
We anchor development to business metrics:
- Retention improvement targets.
- Feature flag incremental rollouts.
- Cost vs performance trade‑offs (serverless vs managed backend).
Clients get:
- Detailed API contracts.
- Versioned releases with changelogs.
- Regression test reports.
- Product Discovery & Architecture Review
- MVP to Full SaaS Development
- Dedicated Engineering Support
- Developer Documentation & Enablement
- Post‑Launch Support & Roadmapping

Deventee is not a gig‑shop that glues frameworks together. We build robust systems that:
- Handle growth and real user load.
- Are testable, observable, and maintainable.
- Are architected for long‑term business value.
