Hi, I'm John and am Web Application Developer specializing in full-stack systems, AI integrations, and workflow automation. https://johnedward.vercel.app/ I help businesses build scalable web applications, AI-powered tools, and backend systems that reduce manual work, streamline operations, and improve customer workflows. My work often combines modern web development with AI automation, allowing companies to turn repetitive tasks into intelligent systems. What I commonly build • Full-stack web applications (React, Next.js, Node.js, Python) • AI chatbots using OpenAI or custom LLMs • Backend APIs and automation systems • WhatsApp / Telegram chatbot platforms • AI-powered business tools and internal assistants • Data processing pipelines and workflow automation Many of the solutions I build connect multiple services through APIs, creating automated systems that handle customer conversations, process large datasets, and trigger business workflows automatically. Technologies I frequently use Python • Node.js • REST APIs • OpenAI / LLM integrations • Web automation • Database systems • Cloud deployment My focus is delivering systems that are reliable, scalable, and easy for businesses to maintain. If you're looking to build a web application, integrate AI into your product, or automate a workflow, feel free to reach out and we can discuss the best approach for your project.
An Elixir developer is a software engineer who builds scalable, fault-tolerant backend systems using the Elixir programming language and the Erlang virtual machine. Hiring an Elixir developer gives you access to concurrent, distributed application expertise built on the BEAM, the same runtime that powers global telecom and messaging infrastructure. Elixir engineers specialize in writing maintainable functional code that handles millions of simultaneous connections without breaking under load.
An Elixir programmer designs, develops, and maintains server-side applications that prioritize concurrency, low latency, and uptime. Because Elixir runs on the BEAM virtual machine, an Elixir engineer can build systems that recover from failures gracefully and scale horizontally across nodes. This makes the language a strong fit for real-time messaging, financial transaction processing, IoT backends, and high-traffic web APIs.
Beyond writing code, an experienced Elixir consultant typically architects supervision trees, designs OTP behaviours, and shapes the deployment topology for production workloads. They also handle integration with frontend frameworks, third-party APIs, databases, and message brokers, so your Elixir backend connects cleanly to the rest of your stack.
The work an Elixir developer produces depends on whether you need a greenfield application, a feature added to an existing codebase, or a performance audit. Typical deliverables include:
Strong Elixir engineers work fluently across an ecosystem of mature libraries and tooling. Look for hands-on experience with:
Elixir's concurrency model makes it particularly attractive in domains where uptime and parallelism matter. Companies in fintech use Elixir for payment processing, ledger systems, and real-time risk engines. Messaging, chat, and collaboration platforms rely on the BEAM to maintain millions of persistent connections. Healthtech teams use Phoenix for HIPAA-aware applications, while ecommerce and marketplace operators choose Elixir for inventory, pricing, and order fulfillment services. IoT and telematics businesses adopt Nerves and Elixir to coordinate fleets of devices, and ad tech firms use Broadway to handle high-throughput event pipelines.
A capable Elixir developer should demonstrate functional programming fundamentals, real OTP experience, and production deployment knowledge. Review their public GitHub or Hex.pm contributions, look for Phoenix or LiveView projects in their portfolio, and check whether they have shipped applications that handle real concurrency, not just CRUD APIs. Past work with Ecto, distributed clusters, or supervision tree design is a strong signal that they understand the language beyond the surface.
Useful interview questions to ask candidates:
Freelancer.com connects you with a global pool of Elixir engineers, Phoenix specialists, and OTP consultants across every time zone. You can compare detailed profiles, portfolios, ratings, and verified reviews before you commit, so you choose a developer whose experience matches your project. Clients set their own budgets and receive competitive bids, and Milestone Payments protect your funds until deliverables are approved. Whether you need a short consulting engagement, a Phoenix MVP, or long-term backend ownership, you can hire on Freelancer.com with confidence.
Ready to build with the BEAM?
Hiring an Elixir developer is straightforward when you approach it methodically. The clearer your brief, the better the bids you receive, and the more accurately you can compare candidates against the technical realities of your project. The three steps below walk you through posting, reviewing, and awarding an Elixir engagement.
Your project post is the single biggest determinant of bid quality. A precise brief filters out generalists and attracts Elixir engineers whose Phoenix, OTP, and Ecto experience genuinely matches your needs. Head to the
Bids are short proposals, not just price quotes. A strong Elixir freelancer will reference your brief, ask sharp clarifying questions, and outline an approach that reflects real OTP and Phoenix experience. Read each proposal carefully and shortlist candidates whose interpretation of the work aligns with what you actually need built.
The final decision combines proposal quality with profile evidence. For Elixir work, weigh consistency across multiple completed projects rather than a single impressive sample, because production stability and OTP discipline show up over time. Look closely at portfolio depth, client reviews, and verified credentials before awarding.
Both work on the BEAM virtual machine and share the same runtime concurrency model, but Elixir has a more modern syntax, the Mix tooling, and the Phoenix web framework. Many Elixir developers can read and write Erlang when needed, particularly for low-level OTP work or interfacing with legacy Erlang libraries.
Timelines depend on scope. A small Phoenix API or LiveView feature can be built in one to three weeks, while a full production application with authentication, background jobs, and deployment pipelines typically takes one to three months. Rewrites and distributed systems work usually require longer engagements.
Yes. Many clients hire Elixir freelancers on Freelancer.com for code reviews, performance audits, Phoenix upgrades, or building a single feature such as a LiveView dashboard or an Oban job pipeline. You can scope the work as a fixed-price project or hourly engagement.
For most early-stage products and feature additions, a single experienced Elixir consultant is enough, especially given how much Phoenix and OTP cover out of the box. If you are building a large distributed platform with multiple services, hiring two or more Elixir engineers, plus a DevOps specialist, gives better coverage and faster delivery.
It helps. Phoenix LiveView reduces the need for heavy frontend frameworks, but most production projects still involve some JavaScript, TypeScript, or HTML and CSS work. Many Elixir developers also bring experience with Ruby, Go, or Python, which is useful when integrating with existing services.
