# Engineering Services & Systems Architecture Consulting

Sahil Langoo provides specialized technical consulting, systems architecture design, and high-performance implementation for modern software organizations, digital agencies, and engineering teams.

## Core Capabilities & Service Offerings

### 1. Server-Side Conversion API (Meta CAPI) & Edge Gateways

- **Overview**: Implement resilient, privacy-compliant server-side tracking pipelines on Cloudflare Workers and Hono.
- **Outcomes**: Bypasses client ad-blockers and Safari ITP limitations; achieves 8.5+ Event Match Quality (EMQ); offloads tracking payloads from client main thread with zero impact on Interaction to Next Paint (INP).
- **Deliverables**: Edge worker codebase, deterministic event deduplication (`event_id`), SHA-256 user data hashing, and monitoring telemetry.

### 2. High-Performance Static Web Architecture (Astro & Edge CDN)

- **Overview**: Build or migrate enterprise web properties to Astro static architectures with zero runtime JavaScript defaults.
- **Outcomes**: Guaranteed 0.00 Cumulative Layout Shift (CLS), sub-50ms global TTFB across Cloudflare edge nodes, and 100/100 Google Lighthouse Core Web Vitals.
- **Deliverables**: Type-safe content collections, automated Schema.org JSON-LD structured data, accessible design tokenization (daisyUI 5 / OKLCH), and CI build verification.

### 3. Edge Security & Bot Protection (Cloudflare Turnstile)

- **Overview**: Replace legacy, invasive CAPTCHAs with invisible Cloudflare Turnstile token validation executed directly at the edge.
- **Outcomes**: Eliminates 99.9% of automated submission spam without degrading user conversion rates.
- **Deliverables**: Client widget integration, edge token verification handlers, and rate-limiting security rules.

### 4. Local SLM & Vision Automation Pipelines

- **Overview**: Architect local small language model (SLM) pipelines using Bun, SQLite, and Google Gemma models.
- **Outcomes**: Eliminates recurring cloud API fees for deterministic image classification, structured tagging, and metadata extraction.
- **Deliverables**: High-throughput batch processing CLI tools, deterministic JSON schema enforcement, and local worker pools.

### 5. Technical SEO, Programmatic SEO (pSEO), GEO & Search Telemetry

- **Overview**: Architect end-to-end technical search pipelines, programmatic SEO taxonomies, machine-readable knowledge bases for AI engines (GEO / AEO), and comprehensive behavioral telemetry across modern web properties.
- **CMS & Content Pipelines**:
  - Astro Markdown/MDX Content Collections CMS with strict Zod runtime schema validation.
  - Headless CMS configurations (Strapi, WordPress Headless) paired with decoupled SSG frontends.
  - Programmatic SEO (pSEO) taxonomy architecture: dynamic hub generation, categorized collections, and automated internal linking equity graphs.
- **Metadata, Schema & Rich Results**:
  - Dynamic OpenGraph and Twitter Card generation engines with build-time social image rendering.
  - Automated Schema.org JSON-LD graphs (`WebPage`, `TechArticle`, `Person`, `Organization`, `JobPosting`, `SoftwareApplication`, `BreadcrumbList`) validated against Google Rich Results standards.
  - Strict canonical URL engines and automated broken link/anchor crawler verification (`Linkinator`).
- **Crawler Directives & Machine-Readable AI Endpoints (GEO / AEO)**:
  - RFC 9309 compliant `robots.txt` configuration cleanly segmenting general search bots and authorizing AI crawlers (`GPTBot`, `PerplexityBot`, `ClaudeBot`).
  - Automated XML sitemaps (`sitemap-index.xml`) with dynamic priority scoring and last-modified timestamps.
  - Machine-readable knowledge bundles (`/llms.txt`, `/llms-full.txt`, and clean `.md` endpoints) formatted per the OKF / llmstxt.org v2 standard for LLM citations.
- **Search Telemetry, Behavioral Analytics & Observability**:
  - Google Search Console (GSC): Continuous crawl rate monitoring, sitemap submission, indexing error triage, and search impression analysis.
  - Google Analytics 4 (GA4) & Google Tag Manager (GTM): Custom event dispatching, conversion funnel modeling, and consent-mode tracking.
  - Microsoft Clarity: Behavioral heatmap analysis, session recording instrumentation, and rage-click UX debugging.
  - Sentry: Real-time production exception tracing, performance profiling, and distributed tracing across edge and client boundaries.
- **Proven Client Implementations**:
  - **Taffin.Tech**: Programmatic job taxonomy architecture, automated JobPosting JSON-LD schemas, and GSC indexation monitoring.
  - **Eresolution Consultancy Services**: Multi-surface enterprise lead funnels, GTM event triggers, GSC indexing pipelines, and Microsoft Clarity heatmaps.
  - **HackerForce**: Technical e-commerce SEO, dynamic metadata pipelines, and automated sitemap generators.
  - **SoulMedia**: Headless Strapi CMS integration, OpenGraph social engines, and GA4 telemetry.

## Engagement Models

1. **Architecture Advisory & Code Audits**: Comprehensive architectural review of existing codebases, performance bottlenecks, and edge infrastructure with actionable remediation roadmaps.
2. **Fixed-Scope System Implementations**: Turnkey delivery of edge proxies, CAPI integrations, or static platform migrations.
3. **Fractional Systems Engineering**: Dedicated weekly bandwidth to architect, review, and ship resilient infrastructure alongside internal teams.
