• Highlight projects and technical achievements
• Balance technical depth with business impact
• Format for both ATS and technical recruiters
• Include GitHub, portfolio, and technical links

Tech Resume Philosophy

The 5-Stage Hiring Funnel

Understanding where your resume gets evaluated determines what to optimize:

Stage	Who/What	What They Optimize For
1	ATS Parser	Standard headers, \pdfgentounicode=1, no images, parseable text
2	Keyword Filter	Critical keywords present (≥5 mentions in JD = Critical tier)
3	LLM/AI Ranking	Context-rich engineering sentences (not keyword density)
4	Technical Recruiter	Readable in 6 seconds, clear tech stack, no jargon without context
5	Engineering Manager / HM	Credible architecture, technical reasoning, defensible claims

Dual-Stack Rule: Stages 1–2 and Stage 3 are NOT in conflict. Keywords embedded in evidence-rich engineering sentences satisfy the keyword filter AND LLM ranker simultaneously. You do not need to choose between ATS optimization and human readability.

Evidence Grounding Rule

Every project bullet must be traceable to one of:

• A specific file, import, or function in a GitHub repository
• A field in the Engineering Evidence Database
• A design document, PRD, or architecture diagram
• A measurable metric you can defend in an interview

Bullets without evidence sources are either rewritten until evidence exists or removed.

Company-Specific Bullet Style Guide

Writing style is inferred from JD content (not company name). Use these as guidance:

Company Type	Signal Words in JD	Bullet Style
rtCamp / Canonical / Automattic	"open-source", "contribute", "PR", "community"	Lead with contributions: PRs merged, features shipped, community impact
Atlassian	"developer tools", "API", "DX", "integration"	Lead with API design, SDK quality, developer adoption metrics
Razorpay / PhonePe	"scale", "transactions", "fintech", "reliability"	Lead with reliability, scale, throughput, and system design decisions
Darwinbox	"product", "SaaS", "enterprise", "HR"	Lead with product impact, user-facing features, customer outcomes
Microsoft	"Azure", "cloud", "distributed", "platform"	Lead with system design, reliability, scale, and team collaboration
Amazon	"customer", "ownership", "data-driven"	Lead with customer impact, measurable outcomes, ownership scope
Google	"scale", "SRE", "distributed", "ML"	Lead with scale metrics, system design decisions, efficiency gains

Experience Section for Tech Roles

The PACTI Technical Bullet Formula

[Problem] + [Action] + [Core Technical Decision: Why X over Y?] + [Implementation] + [Impact]

AI/ML Before/After Example:

❌ WEAK:
- Implemented Isolation Forest for anomaly detection
- Used FastAPI for the backend
- Added Redis caching

✅ PACTI:
- Chose Isolation Forest over DBSCAN for log anomaly detection because the
  system had no labeled data; IF's unsupervised nature handled varying log
  densities robustly — reduced false alert rate by ~27% during development
  testing on 15 simulated incidents

- Chose FastAPI over Flask for the log ingestion API because native async
  support was critical for concurrent log batch processing; built 5 REST
  endpoints with automatic OpenAPI docs, handling ~500 entries per batch
  during local performance testing

- Added Redis caching to the API response layer because PostgreSQL query
  latency spiked to 800ms under concurrent load; reduced average response
  time to ~120ms during load testing with 50 concurrent requests

Notice what PACTI adds: The "Core Technical Decision" (why X over Y) is the element that signals senior engineering thinking. It is also the most common interview question trigger — every PACTI bullet prepares you for the follow-up question.

Tech-Specific Tips

GitHub Profile Optimization

Make sure your GitHub shows:

• Pinned repositories (your best 6)
• Green contribution graph (activity)
• README for profile
• Complete project READMEs

Project READMEs should include:

• What the project does
• Technologies used
• How to run it
• Screenshots/demos
• Your contributions (for collaborative projects)

Dealing with Tech Stacks

If you match their stack:

• Lead with those technologies
• Quantify your experience with them

If you don't match exactly:

• Emphasize transferable skills
• Show learning ability
• Highlight similar technologies
• Example: "Django" → "Extensive Python web framework experience (Django); quick to ramp on new frameworks"

Technical Interviews Prep Note

Tech resumes should support your interview:

• Only claim technologies you can discuss deeply
• Be ready to explain every project listed
• Know the architecture of systems you've built
• Have stories ready for each bullet

• Avoid tables and graphics

For Tech Recruiters:

• Show technical depth
• Include metrics and scale
• Demonstrate problem-solving
• Show you understand systems
