Abhay Vachhani

Software Engineer

Remote• LinkedIn• GitHub

Software Engineer with 3+ years of hands-on development experience, from freelancing to professional roles. I build backend services, AI-powered features, automation scripts, and cloud deployments using Python and JavaScript, with a focus on API design, data processing, and computer vision. I ship end-to-end from architecture to production, use documentation and AI tools to learn and move fast, and improve team workflows with CI/CD and DevOps automation.

Backend Developer / DevOps Engineer

Jun 2024 - Present•Remote
  • ›Configure and manage production Linux servers, maintaining critical Docker containers across development and production environments. Developed custom build.sh scripts for reproducible setup.
  • ›Implemented atomic deployments using Docker Compose with health checks — builds new containers in parallel and only switches traffic upon success, ensuring zero downtime and automatic fallback.
  • ›Enforced strict server hardening: disabled root login, SSH key-based auth, UFW firewalls blocking all non-essential ports.
  • ›Configured Nginx as a secure reverse proxy with automated SSL certificate renewal (Certbot) and header optimizations.
  • ›Architected the backend for TaskBoard — a voice-enabled productivity platform with real-time collaboration using Socket.io and LiveKit (WebRTC) for video meetings.
  • ›Deployed a Python-based facial recognition system (Vision AI) and optimized the environment for heavy AI/ML workloads using containerization.
  • ›Built scalable backend services for iWell Care with background job processing using BullMQ and Redis for document parsing and AI summarization.
  • ›Built and deployed WhatsApp bots for user onboarding and feature exploration.

Independent AI Assessment

Scope: Infrastructure & Operations•Reviewer: Gemini 3 Pro High (Fast Mode)•Agent: Antigravity (Google DeepMind)

This assessment specifically evaluates infrastructure, DevOps, and operational capabilities — one dimension of a broader engineering skillset.

“Abhay Vachhani distinguishes himself from typical candidates through proactive tool building and battle-tested resilience. Unlike engineers who merely configure managed services, Abhay understands the primitives of Linux, networking, and containerization because he has built his own solutions from scratch (e.g., a custom AI-powered WAF).”

Key Strengths

Operational Resilience

When faced with a critical security breach (crypto-miner infection via a React vulnerability), Abhay did not just patch the hole; he fundamentally hardened his infrastructure with resource limits, isolation, and proactive monitoring tools. He learns through fire.

Pragmatic Automation

Instead of over-engineering solutions with complex tools for his scale, he implemented atomic deployments using Docker Compose and custom bash scripts. This demonstrates a maturity to choose the "right tool for the job" rather than "resume-driven development."

Security-First Mindset

His implementation of a custom AI-Analysis Web Application Firewall (WAF) to parse Nginx logs and block threats via UFW is exceptional for his experience level, showing advanced DevSecOps potential.

Areas for Growth

Enterprise Tooling Gap: Experience is currently rooted in manual/scripted management of VPS instances rather than cloud-native orchestration (Kubernetes) or Infrastructure-as-Code frameworks (Terraform, Ansible).
Scalability Limits: Current workflows (custom scripts, cron jobs) are highly effective for his current scale (6 servers, 140+ containers) but may require adapting to standard enterprise patterns for larger, multi-team environments.

Mitigating Factor: His deep understanding of the underlying systems (Linux, Docker, Networking) suggests he will learn enterprise abstractions significantly faster than candidates who only know the tools but not the foundations.

Final Verdict

“Abhay is a "Builder-Operator" ideal for high-growth environments. He bridges the gap between backend logic and infrastructure reality. He will not just report that a server is down; he will SSH in, diagnose the kernel panic, fix the root cause, and write a script to ensure it never happens again.”
