FREELANCE ENGINEERING & TECHNICAL CONSULTING.
I design, build, and secure software systems for early-stage startups and engineering teams. Specializing in concurrent Go/Python backends, authorized security audits, containerized DevSecOps automation, and local-first AI pipelines.
Core Service Pillars
Backend Engineering & MVP Development
High-throughput concurrent services built in Go and Python. Clean REST/gRPC API architectures, SQLite/PostgreSQL data modeling, and end-to-end MVP execution designed for sub-millisecond response times.
- Concurrent worker pools & raw socket networking
- Resilient database journaling & schema design
- Fully tested, zero-dependency microservices
Cybersecurity & Vulnerability Assessment
Authorized security evaluations for web applications and APIs. Systematic testing for OWASP Top 10 vulnerabilities, authentication bypasses, IAM misconfigurations, and air-gapped forensic log auditing.
- Authenticated API & web app vulnerability testing
- AWS IAM & cloud access policy audits
- Actionable reports with exact reproduction proof
DevSecOps & Cloud Infrastructure
Production GitOps deployment pipelines, container attack surface reduction via Google Distroless, and automated security scanning integrated directly into GitHub Actions.
- 99.3% Docker container image reduction (1.1GB → 8.4MB)
- Automated Trivy & secret scanning pipeline gates
- Hardened Kubernetes manifests & Helm deployments
AI Systems & Document Intelligence
Pragmatic AI automation without hallucinations. High-volume OCR ingestion pipelines, vector databases (Milvus), codebase AST grounding, and local private LLM integrations.
- Asynchronous RabbitMQ OCR & vector search pipelines
- Grounded code intelligence with verified AST references
- Zero-cloud private LLM integrations with Ollama
How We Can Work Together
Scoped MVP Build
2 TO 4 WEEKS · FIXED SCOPE
Turn your architecture specification into a working, containerized software MVP. Includes backend microservices, clean API documentation, database schemas, and automated test coverage.
Security Hardening Audit
1 TO 2 WEEKS · FIXED DELIVERABLE
Thorough defensive security evaluation of your web app or cloud infrastructure. Identifies injection flaws, authorization gaps, and cloud misconfigurations with concrete remediation PRs.
DevSecOps & Cloud Retainer
WEEKLY OR MONTHLY ENGAGEMENT
Ongoing engineering support for CI/CD pipeline automation, distroless Docker packaging, Kubernetes manifest reviews, and system performance tuning.
Capabilities Backed by Real, Documented Software.
I don't make claims I cannot reproduce. Every service pillar maps to a live, open-source system designed, coded, and benchmarked by me.
Client Questions & Process
How do you structure freelance engagements?
I operate primarily on fixed-scope project milestones or dedicated weekly sprint retainers. Every engagement begins with an intake call or written specification review where we agree on concrete deliverables, acceptance criteria, and timelines before writing any code.
What is your primary tech stack?
For backend services and CLI tools, I specialize in Go and Python. For databases, I work with PostgreSQL and SQLite. For infrastructure, I use Docker (multi-stage Distroless), GitHub Actions, Kubernetes, and Linux internals. For AI pipelines, I work with Tesseract OCR, Milvus, and Ollama.
Do you sign NDAs and work with international clients?
Yes. I routinely sign mutual Non-Disclosure Agreements (NDAs) prior to discussing proprietary code or infrastructure. I work remotely with clients worldwide and communicate asynchronously with daily or weekly written status summaries.
READY TO DISCUSS YOUR PROJECT?
Send over your project specification, timeline, or security requirements. I will review and reply within 24 hours.
