I’m Junaid Farooq, a Senior Software Consultant with 9+ years of experience building and scaling backend, distributed, and event-driven systems across healthcare, fintech, communications, and consumer platforms.

My core expertise is in Elixir, Phoenix, and Phoenix LiveView, where I design systems that prioritize correctness, scalability, reliability, and long-term maintainability. I’ve worked with early-stage startups and scaled products alike, owning systems from architecture and domain modeling to production support in high-traffic environments.

• Elixir & Phoenix backend systems (REST, GraphQL, LiveView)
• Distributed systems and event-driven architectures
• RabbitMQ (publishers, consumers, retries, DLQs, idempotency)
• Payments, billing, ledger-style systems, and financial workflows
• Form builders with versioning, validations, and dynamic schemas
• Notification systems (email, SMS, async pipelines)
• Elasticsearch & OpenSearch for fast, structured, and pattern-based search
• Slack & Telegram bot development, including webhooks and APIs
• PostgreSQL, ClickHouse, and data-heavy reporting systems
• Production debugging, performance tuning, and observability

• Led and contributed to large-scale healthcare platforms, including backend systems used by hospitals and clinics
• Built and maintained fintech systems involving wallets, payments, credits, and reporting
• Migrated monolithic systems to microservices and event-driven architectures
• Designed and operated high-throughput message pipelines using RabbitMQ and Broadway
• Implemented Hot Code Upgrades in Elixir (published technical article)
• Worked extensively with AWS, physical servers, monitoring, and storage systems

I prefer domain-driven design over CRUD-heavy architectures, and I take full ownership of systems — from understanding business problems to delivering reliable production solutions. I enjoy working on hard problems, mentoring engineers, and improving engineering standards within teams.
