Experience

IT Consultant & Founder | any-apps.com

2023 - Present (Remote - US, Europe & Middle East clients)

Established a boutique IT consultancy to provide end-to-end development and DevOps solutions for international clients across the US, Europe, and the Middle East, working fully remote across multiple time zones.
Management & Leadership: Lead and coordinate a remote team of engineers and subcontractors; own project planning, task breakdown, workload allocation, code review, and delivery tracking to keep multiple concurrent engagements on schedule.
Client Management: Serve as the primary technical point of contact for clients — handling scoping, estimates, status reporting, and expectation management in async-first English communication.
Technical Decision Making: Drive architecture and technology decisions (stack selection, build-vs-buy, cloud vendor and service choices) by evaluating trade-offs across cost, performance, scalability, and maintainability; document rationale and align stakeholders before committing.
System Design & Analysis: Translate business requirements into system architecture and technical specifications — data modeling, API contracts, and design diagrams — bridging client goals and engineering execution.
Private clients (multiple engagements): Architected and delivered complete AWS environments (Dev/Prod) end-to-end — infrastructure as code with Terraform/OpenTofu and Ansible, backend services in Django, Redis, and WebSockets, CI/CD via GitHub Actions (automated Node.js builds, EC2 synchronization), and integrations such as NodeBB on AWS EC2.
Cloud & Cost Management: Managed complex AWS environments (VPC, S3, RDS, CloudWatch) and performed cost optimization to reduce infrastructure overhead. Managed global DNS/Email via Cloudflare and GoDaddy.

Founding Infrastructure & Backend Engineer | Confidential Startup

2024 - Present (Remote)

Research and design of the infrastructure architecture for an early-stage startup, from domain strategy through production deployment.
Domains, DNS & Email Security: Registered and configured domains across Cloudflare and GoDaddy, set up DNS records, and secured email deliverability with SPF/DKIM/DMARC policies.
Cloudflare Security Hardening: Applied SSL/TLS hardening, WAF rules, and access policies to protect applications and reduce attack surface.
Static Site Delivery: Deployed static pages for development via GitHub Actions pipeline to Cloudflare Pages.
Cloud Infrastructure (IaC): Provisioned AWS infrastructure (EC2, RDS, S3) with IAM policies using Terraform/OpenTofu and Ansible across production, staging, and dev environments.
Backend: Developed a Django backend with Celery task pipelines, supported by 200 unit tests and processing a dataset of 10 million records.
Frontend: Built a Next.js/React application with 300 unit tests, shipped through a CI/CD pipeline using pnpm and Bun.
SEO & Security: Enhanced on-page SEO and application security hardening across the stack.
Payments: Integrated multiple payment providers — Stripe, Square, and NMI — behind a configuration-driven abstraction layer, enabling switching payment gateways via configuration without code changes.
SMS & Phone: Integrated Twilio for SMS and phone-based notifications and verification workflows.
Rate Limiting: Implemented rate limiting and throttling on API endpoints to protect services from abuse and ensure fair usage.
Public API: Designed a versioned public API for external clients with API key authentication and an OpenAPI specification for self-serve integration and documentation.

Freelance Fullstack & DevOps Engineer

2017 - 2024 (Remote - International clients)

Managed long-term remote engagements directly with overseas clients and teams, delivering features and infrastructure asynchronously across time zones.
CI/CD Engineering (2024): Set up automated pipelines for Flask apps (GitHub Actions to AWS) and Node.js apps (GitLab CI/CD).
AI Integration (2023): Developed Node.js (React/Express) features to interface with AI APIs.
Document Tooling (2022): Built a specialized PDF to DOCX converter using Node.js.
Application Security: Developed robust authentication modules for Node.js/MERN stacks (2017) and PHP/Laravel systems (2018).
