I have a queue of long-term Flutter projects and the next one in line is a brand-new Faith Tech productivity app. The build must feel first-class on both iOS and Android and be coded entirely in Flutter 3.x with sound null-safety, modern state management (Provider, Riverpod or BLoC) and clean architecture. The initial release needs three core modules developed from scratch: task management, calendar integration and note-taking. I’m open to your suggestions on extra workflow boosters, but these three must ship fully polished, tested and production-ready. Code quality, readable commits and automated unit/widget tests are non-negotiable. I already have backend APIs in place, so the work focuses on UI/UX, state handling, offline support and integrating the existing REST endpoints. You&...

I have an enterprise decision-analysis product on the roadmap and I need a senior-level Microsoft Azure engineer who is comfortable taking full ownership of the Azure development. The core requirement is an unsupervised machine-learning pipeline—deployed and managed in Azure—that can ingest raw data, uncover patterns autonomously, and feed those insights into the application’s decision engine. Here is what I have in mind: data lands in an Azure Data Lake, is processed through Azure Databricks or Synapse, and the unsupervised models (clustering and anomaly-surfacing techniques are likely candidates) are trained and versioned in Azure Machine Learning. Model output then needs to be exposed via a RESTful endpoint, secured with Azure AD, and consumed by the front-end service...

Logs centralizados, métricas, alertas e versionamento de infraestrutura são parte d...
I need a production-ready SaaS platform that lets different client accounts spin up their own AI voice agents in Malayalam, English and Hindi. The agents will answer inbound calls and place outbound ones for customer support first, but they must also be able to capture leads, run outreach campaigns and close basic sales when flows allow. Voice connectivity must be plug-and-play with TeleCMI, Twilio, Exotel or any comparable cloud telephony number. I expect full IVR support, dynamic call routing, call recording and the ability to fall back to a live agent when confidence drops. Key components and expectations • Multi-tenant architecture with role-based access so each tenant only sees its own data. • NLU, ASR and TTS tuned for the three target languages; switching between the...

I’m building a complete digital solution for a home-cleaning service and need someone who can handle both the development of the product and the hosting setup that keeps it running smoothly. The product itself breaks into two parts: 1) An Android application that lets customers: • browse local cleaners • book appointments through a real-time calendar • track their cleaner’s arrival via GPS • leave ratings and written reviews after each job 2) A responsive web portal that mirrors the same customer experience for desktop users and includes an admin dashboard where I can approve cleaners, adjust pricing, review bookings and reply to customer feedback.

I’m building a full-scale e-commerce solution and I want every piece—web store and mobile apps—running on a clean microservice architecture. The core idea is to separate catalog, cart/checkout, payments, user management, and notification services so they can scale independently and be deployed through containers without downtime. For the customer-facing side, I need: • A responsive web application that feels fast on desktop and mobile browsers, complete with product search, detailed pages, real-time inventory, shopping cart, secure checkout, and an admin dashboard for product and order management. • Native (or high-performance cross-platform) iOS and Android apps.

I am rolling out a full CI/CD pipeline on AWS and want it driven by Spinnaker. The work starts with connecting Spinnaker to our existing Git repos, packaging a Java-based service, and automating its promotion through our Eaac environments via Jule. Key expectations • Spinnaker configured on AWS with the right roles, accounts, and artifact stores so a commit can move from build to deploy without manual steps. • Pipeline stages that compile and unit-test the Java code, create versioned artifacts, run automated checks, and push straight to production once everything passes—with easy rollback built-in. • Clean, reusable templates so additional Java services can be onboarded quickly. • Clear hand-off documentation and a brief walk-through so the team can ope...
I have a working prototype of a messaging layer that sits directly on top of Gmail. The backend (Go micro-services on GCP, MongoDB Atlas) is solid enough for now, but the React frontend needs love before I can call the product “production-ready.” Here’s where I need you to focus: - UI/UX problems • Layout and design • User interactions - Performance issues Your first task is to audit the existing React 18 codebase, isolate the pain points above, propose fixes, then implement them. I want the interface to feel native inside Gmail—clean, intuitive, and fast, with bundle size and render times kept in check. Tech context you’ll touch: React 18 with hooks and Context API, Go services served via Cloud Run, MongoDB Atlas, GitHub for version ...

Cuento con un sistema tipo SaaS ya desarrollado y necesito llevarlo a producción para poder ofrecerlo a diferentes empresas y clientes finales. El código está listo, pero aún falta ajustar la infraestructura, asegurar la escalabilidad y, sobre todo, dejar operativa la funcionalidad de Administración de usuarios, ya que será el núcleo para crear, editar y controlar los accesos de cada compañía que contrate el servicio. Lo que espero de tu parte es una auditoría rápida del estado actual, la preparación del entorno cloud (puede ser AWS, GCP, Azure o el que mejor se adapte al stack existente) y la puesta en marcha de despliegues continuos. Me interesa que automatices todo lo posible – desde la base de da...

I am rolling out a new environment that spans Terraform-managed infrastructure, automated Github Actions workflows, and integrations with Snowflake and Mulesoft. The area where I need the most hands-on help is AWS—specifically provisioning, securing, and optimising EC2 instances, S3 storage buckets, and a series of serverless Lambda functions that glue everything together. Here’s the flow I’m targeting: • Terraform drives all resource creation so our stacks remain fully reproducible. • Github Actions handles CI/CD, triggering Terraform plans/applies and Lambda deployments on every merge. • Data exchanged between Snowflake and our micro-services is exposed through Mulesoft APIs running behind AWS resources. What I need from you: a clean, modular Te...
I’m ready to move the entire and Extensive Base44 stack—both its underlying data and the web applications that sit on top of it—to a new environment without breaking anything users rely on today. The migrated solution must keep user authentication fully functional, preserve all current database connections, uphold every existing API endpoint, and leave the front-end behaving exactly as it does now. You’ll start by auditing the current Base44 setup, mapping data schemas, application dependencies, and authentication flows. From there, I expect a migration strategy that covers staging, incremental data transfer, automated testing, and a cut-over plan with minimal downtime. Once live, we’ll run validation tests together to confirm logins, database reads/writes, A...

Our Python-based platform has been in production long enough to accumulate a handful of thorny issues. I want a fresh, senior-level pair of eyes to go through the codebase, diagnose what’s really happening, and bring the system back to a stable, performant and secure state. Scope of the audit • Security: probe for obvious misconfigurations, insecure dependencies, injection risks and any surface that could be exploited. • Performance: profile critical paths, highlight bottlenecks, and suggest optimisations that translate into measurable speed-ups or lower resource usage. • Code quality: evaluate structure, readability and test coverage; recommend refactors that reduce technical debt. Highest priority fix Functionality issues come first. Anything preventing cor...
My Bitbucket Pipelines configuration has begun throwing errors, and every push now stalls the workflow. I need a CI/CD-savvy engineer to audit the existing , trace the root cause of the failures, and deliver a clean, reliable pipeline that runs end-to-end without manual intervention. You’ll have full access to the repository’s current pipeline file, build logs, and any environment variables I already store in Bitbucket. Please identify mis-configured steps, outdated images, missing secrets, or anything else that blocks the build, test, or deploy stages. If a change to Docker images, caches, or parallel step logic is required, document what you adjusted so I can maintain it later. Deliverables • Updated committed via pull request • Brief changelog explaining eac...
I already have a fully functional kitchen-operations and staff-management web app built with the Emergent framework; the entire AI-generated codebase is in my repository and the core logic works as expected. What I need now is a pragmatic engineer to shepherd it from “working prototype” to “reliable production release.” Your focus starts with UX streamlining, specifically navigation. The current menu structure feels cluttered, several key links are buried, and overall ease of use drops when staff jump between order queues, inventory, and shift planning. I want clearer hierarchy, improved link visibility, and a flow that lets kitchen staff reach any core screen in two taps or fewer—even on a busy service night. Alongside that, I need validation of all user-pe...
