From 29,279 reviews, clients rate our CI/CD Experts 4.9 out of 5 stars.Our team relies on a fully custom-built CMS & CRM written in JavaScript/Node.js. It underpins everything from project and retainer tracking to sales pipelines, and it already talks to Gmail, Google Docs, and ChatGPT to automate daily workflows. I need a reliable technical partner who can step in whenever our in-house developer is unavailable, keep an eye on system health, and roll out small-to-mid-size enhancements we queue up. Think of it as light “on-call” coverage mixed with incremental feature work rather than a full-time rebuild. Core expectations • Proactively monitor the application, troubleshoot outages or performance drops, and deploy fixes with minimal downtime. • Ship new features or integrations on request—these could range from adding a ...
I have two SaaS sites running on AWS (EC2 + RDS + S3) that I now want moved to BinaryLane () . Both stacks are fairly standard—no exotic networking or custom AMIs—so this should mainly be a clean lift-and-shift and a bit of re-wiring. Scope of work • Spin up equivalent BinaryLane instances, copy the codebases, databases, SSL certificates and cron jobs, and confirm the apps are fully functional on their new hosts. • Point the DNS once we’ve run smoke tests and I give the green light. • Leave all image and document storage on AWS S3; update the apps so they continue to read/write to the same buckets without any broken links. • Recommend and integrate a cost-effective transactional email solution (Amazon SES, SendGrid, Mailgun—whichever you feel gi...

I’m building a mobile application that must perform and feel identical on Android and iOS—I value both equally, so each platform needs the same polish, speed, and attention to detail. My preferred stack is React Native for the shared frontend layer; if you are comfortable weaving native modules or platform-specific tweaks into that workflow, even better. The scope covers everything from setting up the project repository through to releasing a production-ready build on Google Play and the App Store. Along the way I’ll need clean, well-commented code, component-level testing, and logical Git commits so future iterations remain straightforward. Deliverables • React Native codebase configured for Android and iOS • Integration of any native modules we identify as...
Looking for a highly driven Release Manager to take coded projects from approximately 80–90% complete through final verification, stabilization, deployment, and release.

The right person should be highly comfortable working with AI agents, GitHub/Forgejo, deployment workflows, testing, QA, issue tracking, and release coordination. Strong communication with management is essential. When applying, please include: - Development and release tools you are comfortable with - AI coding tools/agents you have worked with - Git, GitHub, Forgejo, CI/CD, testing, and deployment...
I have an Android build that is feature-complete and ready for a final quality sweep before it hits the Play Store. What I need from you is twofold: 1. Manual validation • Run my full functional pass and documented edge-case matrix across a healthy mix of real Android devices and OS versions (no emulators for this stage). • Log every deviation from the acceptance criteria with crystal-clear steps to reproduce, screenshots or screen-captures, device/OS details, and any relevant logs so my devs can fix fast. 2. Automated regression coverage • Build an Appium-based suite that focuses on the critical user flows I will share. • The suite must be reliable enough to drop straight into our CI pipeline (GitHub Actions today, but a simple shell entry point i...
I’m building a fully-featured fintech website and need an experienced developer to take it from concept to production. The platform must let end-users create an account, sign in with a traditional email-and-password flow, and then manage their finances through an elegant, mobile-responsive interface. Core modules will include user authentication, personalised dashboards, payment or transaction handling, rich data visualisations, and a lightweight admin panel. Strong application-level security (OWASP best practices, encrypted credentials, rate limiting) is mandatory, as is fast performance on both desktop and mobile. My preferred stack is React or on the front end, backed by Node.js or Python services that talk to a PostgreSQL database and external payment/banking APIs. I inten...

I’m building a web application and need a seasoned Java full-stack developer to work alongside me from backend through to the React UI. The help I’m after is truly end-to-end: designing or extending Java REST APIs, wiring them into responsive React components, and keeping everything clean, tested, and well-documented. You’ll jump between backend logic (Java 17, Spring Boot, JPA/Hibernate, Maven) and the React frontend depending on the task at hand, always with an eye on performance, security, and code quality. Unit and integration tests, pull-request reviews, and occasional CI/CD tweaks in GitHub Actions and Docker are part of the routine. Acceptance criteria for anything we merge are straightforward: • All automated tests pass and new code meets the existing style...
This project involves building a brand-new utility mobile application in Flutter for simultaneous release on Android and iOS.

I need an experienced DevOps professional (5 + years) to build out our entire on-premises infrastructure. The environment will revolve around Docker containers orchestrated with Kubernetes, with configuration management and repeatable provisioning handled through Ansible. Here’s what I expect to be in place when we finish: • End-to-end CI/CD pipeline that automatically builds, tests, and deploys our applications to the on-prem cluster. • Centralised monitoring and logging stack that gives us real-time metrics, alerting, and searchable logs for every service and node. • A security and compliance baseline baked into the cluster and pipeline: secrets management, role-based access, image-scanning, and audit trails. I’ll provide server access, networking detail...
I need a production-ready Android finance application that will easily clear a formal security review. I will hand over the compliance matrix, API partner documentation, and branding assets; your job is to transform them into a polished, secure app that covers: • On-boarding with KYC checks and biometric login (fingerprint / face). • Encryption at rest and end-to-end TLS in transit. • Account dashboard showing real-time balance updates with a detailed breakdown of holdings. • Searchable transaction history pulled via partner APIs. • Full audit trail—every critical user action logged immutably for future audits. The build must follow modern Android best practices (Kotlin preferred, Jetpack, MVVM, OWASP Mobile Top 10 mitigation) and ship with reproduc...
I’m putting together an intensive, hands-on DevOps workshop tailored to engineers who already understand the basics and now want to sharpen real-world skills. The sessions will revolve around building, deploying, and managing containerised applications with Docker and Kubernetes, then pushing further into Infrastructure as Code using Terraform and Ansible. My goal is to walk participants through live labs rather than slide-only theory: each concept is immediately followed by a guided exercise, troubleshooting tips, and practical take-aways they can apply at work the very next day. To make that happen, I’m looking for a DevOps professional who can: • Design a clear training agenda with step-by-step labs that fit an intermediate skill set. • Provide all supportin...
